  1. Hereby a tutorial to connect an MCP2515 based CAN bus interface to an OrangePi 3 running successfull with Buster minimal nightly with 5.3 kernel. It uses the attached user overlay only and doesn’t need any other overlay. Connections CAN module OPi3 26 pin header Raspberry CAN interface 40 pin header Vcc 3.3 CON12-P01 1 Gnd CON12-P06 6 MOSI CON12-P19 19 MISO CON12-P21 21 CLK CON12-P23 23 CS CON12-P24 24 INT CON12-P26 22 Optional 5V for Transceiver on cheap Chinese modules CON12-P02 Not used when equiped with a 3.3V transceiver Add the attached overlay with the command: sudo armbian-add-overlay spi-h6-mcp2515.dts The file /boot/armbianEnv.txt now contains a line: user_overlays=spi-h6-mcp2515 Reboot the OrangePi 3 Check if the MCP2515 is recognized: pi@orangepi3:~$ dmesg | grep mcp If properly connected it should return a line containing: mcp251x spi1.0 can0: MCP2515 successfully initialized. As stated a can0 interface should be generated check it with: pi@orangepi3:~$ sudo ifconfig -a Bring up the network: sudo ip link set can0 up type can bitrate 250000 Check if the interrupt is hooked: cat /proc/interrupts should return a line like this 46: 1 0 0 0 sunxi_pio_edge 8 Edge mcp251x Check for traffic on the CAN bus with candump from can-utils (sudo apt-get install can-utils) candump can0 spi-h6-mcp2515.dts
  2. For now there's one downloadable Armbian Buster image for the M4V2 from pask. Also the patch needed to prepare your own image : Yon build or download any other M4 image and apply the patch from pask For wifi use this patch from MartinAyotte Download both files Copy these to /lib/firmware/brcm/ Reboot. That's it. Official Armbian for M4V2 comming soon.
  3. Over a year (or two?) I used a PS1-line in my ~/-bashrc with many cryptic ANSI-Escape-codes which were hard to read and edit export PS1='\[\033[1;36m\]\u\[\033[1;37m\]@\[\033[1;33m\]\h\[\033[1;37m\](\[\033[1;32m\]$THEIP\[\033[1;37m\])\[\033[1;31m\]:\[\033[1;36m\]\w\[\033[1;31m\]\$\[\033[0m\] ' Today I did installed Linux Lite 4.6 on a PC (a former Chromebox) and did see the nice Powerline prompt and did try to use that on a nanoPi Neo2. I installed the packages fonts-powerline & powerline and copied the powerline-script /usr/share/powerline/bindings/bash/ from the pc to the NanoPi Neo2. It did work after I used UTF8 translation in pUTTY, but it wasnt very perfomant So I decided to cleanup my PS1 line for better reading, I had to define some variables and then I did put these in my PS1 export line in ~/.bashrc: export THEIP="$(/sbin/ifconfig | grep "inet " | grep -v 127.0.0. | awk '{print $2}')" BRed='\[\033[31;1m\]' BGreen='\[\033[32;1m\]' BYellow='\[\033[33;1m\]' BCyan='\[\033[36;1m\]' BWhite='\[\033[37;1m\]' Reset='\[\033[0m\]' UserPromptPS1='\$' export PS1="${BCyan}\u${BWhite}@${BYellow}\h${BWhite}(${BGreen}${THEIP}${BWhite})${BRed}:${BCyan}\w${BRed}${UserPromptPS1}${Reset} " # \u = User # @ = @ # \h = Host # \w = working directory # \$ = # for root (uid=0) or $ for user That worked well and did give me the same result as my old but bad readable PS1-line Now its - for me - much more easy to edit As Information some more useable color-definition (B before the color is for Bright and colors starting with On are for the Background): Black='\[\033[30m\]' Red='\[\033[31m\]' Green='\[\033[32m\]' Yellow='\[\033[33m\]' Blue='\[\033[34m\]' Magenta='\[\033[35m\]' Cyan='\[\033[36m\]' White='\[\033[37m\]' BBlack='\[\033[30;1m\]' BRed='\[\033[31;1m\]' BGreen='\[\033[32;1m\]' BYellow='\[\033[33;1m\]' BBlue='\[\033[34;1m\]' BMagenta='\[\033[35;1m\]' BCyan='\[\033[36;1m\]' BWhite='\[\033[37;1m\]' OnBlack='\[\033[40m\]' OnRed='\[\033[41m\]' OnGreen='\[\033[42m\]' OnYellow='\[\033[43m\]' OnBlue='\[\033[44m\]' OnMagenta='\[\033[45m\]' OnCyan='\[\033[46m\]' OnWhite='\[\033[47m\]' OnBBlack='\[\033[40;1m\]' OnBRed='\[\033[41;1m\]' OnBGreen='\[\033[42;1m\]' OnBYellow='\[\033[43;1m\]' OnBBlue='\[\033[44;1m\]' OnBMagenta='\[\033[45;1m\]' OnBCyan='\[\033[46;1m\]' OnBWhite='\[\033[47;1m\]' Reset='\[\033[0m\]'
  4. Hello reader I will report here about my experience to watch Netflix as written in the title. To do so, I got a current LE image from @balbes150 (thank you). You may be asking the same question as I do (did), why using the image from balbes and not the official one from the download page ? It is actually quite simple, balbes integrates the latest Kernel for his LE builds. While on a x86 system the kernel isn't so interesting, it is on ARM systems, because a lot of the development happens 1 or 2 year later of the release of the SoC. I have asked him about the different versions he offers for Le Potato: All versions of libreElec (LE) use the common core of aarch64 (64 bits). There is only one 32-bit library (arm) for Netflix. Therefore, I am releasing two versions of LE. ARM version = core of aarch64 + the whole ARM system. aarch64 = core aarch64 + whole system aarch64, this version runs 20-30 % faster than ARM. By the way, it would be interesting to check if Netflix works on Armbian, it may be possible to run it in the environment aarch64 + 32 bit library. So I chose this image: LibreELEC-AMLGX.arm-9.1-devel-20190604084103-a41fdf1-lepotato After writing the image on the SDcard I had to walk through the basic configuration of LE (by the way no SSH - you must use a Display and Keyboard) you find more information here: YouTube A german screenshot film, that guides you through the process of installing the Netflix addon from libdev + jojo + asciidisco Netflix addons; the Kodinerds repository is already part of LE, that saves you some time, update this first. The update and install of the Netflix addon (libdev + jojo + asciidisco), which has some dependencies, is tricky. I had repeated this process several times and a reboot once, because it would only install a few, but not all of the 9 dependencies at once. After 4 or 5 times it confirmed: installed. Now, keep following the YouTube film mentioned above. Adding your credtials to get access to Netflix. WideVine for digital rights mgmnt (DRM), is extracted from ChromeOS - this will download 2Gb Load on the hardware Press the "O" key on the keyboard when playing the video and the service information about the video will be displayed on the screen. It is Software-Decoding for Netflix. 2 cores were running at around 50% and 2 cores were idle (1280 x 720). Testing it on my TV it switched to FullHD at which point it got useless audio and picture were no longer insync. SSH (Secure Shell) During configuration you will see the SSH menu item. You can turn on SSH and you should then change the password!! However, reading the Wiki I got the feeling that this implementation is a bit weird... that said, I would turn it off if you don't need it. WiFi For to me unkown reason the binaries for the USB-WiFi Sticks were removed in 2017: , luckily it is easy to add the driver. cd /storage/.config/ and here you do: mkdir -p firmware and now cd firmware/ unplug your USB-WiFi Stick, plug it in again and do: dmesg | tail -7 you can now see your stick and which binary is missing. Search the binary on this website and complete the line with your binary link: wget reboot no APT There is no working 'apt-get'. TIP: use XBMC's addon browser to enhance your LibreELEC system to be continued
  5. On newer armbian-build it seems that the codec-analog is disabled by default I activated analog-codec in armbian-config ==> System ==> Hardware like in older builds. aplay -l did show the device, but could play. So I did decompile the .dtb with: dtc -I dtb -O dts /boot/dtb/sun8i-h2-plus-orangepi-r1.dtb -o /boot/dtb/sun8i-h2-plus-orangepi-r1.dts Edited the allwinner,sun8i-h3-codec status from disabled to okay: codec@1c22c00 { #sound-dai-cells = < 0x00 >; compatible = "allwinner,sun8i-h3-codec"; reg = < 0x1c22c00 0x400 >; interrupts = < 0x00 0x1d 0x04 >; clocks = < 0x03 0x34 0x03 0x6d >; clock-names = "apb\0codec"; resets = < 0x03 0x28 >; dmas = < 0x14 0x0f 0x14 0x0f >; dma-names = "rx\0tx"; allwinner,codec-analog-controls = < 0x19 >; status = "okay"; phandle = < 0x58 >; }; Then I compiled the .dts back to .dtb: dtc -I dts -O dtb /boot/dtb/sun8i-h2-plus-orangepi-r1.dts -o /boot/dtb/sun8i-h2-plus-orangepi-r1.dtb In armbian-config ==> System ==> Hardware I enabled also usbhost2 & usbhost3 (because no USB-device was recognized at the USB-ports of the NAS-board) and I disabled cir and spi-jedec-nor which I had enabled for a test. After a reboot the soundcard Debian Buster with Armbian Linux 5.3.7-sunxi package bsp-kernel[5.98.191026] u-boot[5.98] dtb[5.98.191026] firmware[5.98] config[5.98] root@opi-r1( aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Codec [H3 Audio Codec], device 0: CDC PCM Codec-0 [CDC PCM Codec-0] Subdevices: 0/1 Subdevice #0: subdevice #0 is working again like in older builds The 2nd Ethernet Port Bus 003 Device 002: ID 0bda:8152 Realtek Semiconductor Corp.

  6. I did that on a NanoPi Neo with the FriendlyARM PCM5102A Hat (;product_id=169 ) using kernel 4.14.87-sunxi and armbian 5.67 (or later would be only 5.65?)

  10. If you use a SIP Voip client on your phone or computer, you can use the sip protocol and scripting to monitor your Armbian board. I'm using Ubuntu Xenial, but other versions should work as well. I have the Linphone client on my phone and I use the free Linphone SIP service. hosts a free SIP service that allows users to make audio or video calls using SIP addresses via the domain You can also send text messages. SIP requires an internet data connection, and my phone is connected via WIFI most of the time except when I'm commuting, so I set up my monitoring chron jobs on the Armbian device to run at times when I'm connected. Set up a SIP account for yourself if you don't yet have one, and set up an account for your device. You can set up free accounts at The example accounts used in this tutorial are: and Replace these with your own accounts. I suggest that you get your Voip service running and tested on your phone and another device or PC before you try and set up SIP scripting on your Armbian device. Install the Linphone console client on your Armbian device (Orange Pi Zero Plus in my case). sudo apt-get install linphone-nogtk When it has installed start the client linphonec You may get a bunch of warnings about unconfigured sound cards and etc. Unless you want to use voice or video, you can ignore these. ........ eventually you will get a linphonec prompt Warning: video is disabled in linphonec, use -V or -C or -D to enable. linphonec> If you type help, you will get a list of commands: linphonec> help Commands are: --------------------------- help Print commands help. call Call a SIP uri or number calls Show all the current calls with their id and status. chat Chat with a SIP uri terminate Terminate a call answer Answer a call pause pause a call resume resume a call transfer Transfer a call to a specified destination. conference Create and manage an audio conference. mute Mute microphone and suspend voice transmission. camera Send camera output for current call. unmute Unmute microphone and resume voice transmission. playbackga Adjust playback gain. duration Print duration in seconds of the last call. autoanswer Show/set auto-answer mode proxy Manage proxies soundcard Manage soundcards webcam Manage webcams ipv6 Use IPV6 nat Set nat address stun Set stun server address firewall Set firewall policy call-logs Calls history friend Manage friends play play a wav file record record to a wav file quit Exit linphonec --------------------------- Now you need to configure your SIP proxy. "help proxy" gives you the relevant commands linphonec> help proxy 'proxy list' : list all proxy setups. 'proxy add' : add a new proxy setup. 'proxy remove <index>' : remove proxy setup with number index. 'proxy use <index>' : use proxy with number index as default proxy. 'proxy unuse' : don't use a default proxy. 'proxy show <index>' : show configuration and status of the proxy numbered by index. 'proxy show default' : show configuration and status of the default proxy. We must use "proxy add". It will start an interactive session. Note the format of the proxy sip address enclosed with < and > linphonec> proxy add Adding new proxy setup. Hit ^D to abort. Enter proxy sip address: <;transport=tls> Your identity for this proxy: Do you want to register on this proxy (yes/no): yes Specify register expiration time in seconds (default is 600): Expiration: 0 seconds Specify route if needed: No route specified. -------------------------------------------- sip address: <;transport=tls> route: identity: register: yes expires: 0 registered: no -------------------------------------------- Accept the above proxy configuration (yes/no) ?: yes Proxy added. linphonec> Password for armdevice on "": Y0uR-pa$$word linphonec> Unregistration on <;transport=tls> done. That's it you are now configured. (not sure what "unregistration" means, perhaps it's a typo and should say registration) Send yourself a test text and quit out of linphonec. Once again "help" is useful: linphonec> linphonec> help chat chat <sip-url> "message"' : send a chat message "message" to the specified destination. linphonec> chat <> "Testing sip messaging" linphonec> terminate No active calls linphonec> quit Terminating... How can you easily send messages from a script? Create a wrapper script using expect (uses tls not bash) If you don't have expect installed then sudo apt-get install expect Create a wrapper expect script called "" #!/usr/bin/expect -f # "this is a message" set message [lindex $argv 0]; spawn linphonec expect "<;transport=tls> done." send "chat <> \"$message\"\r" expect "linphonec>" sleep 10 send "terminate\r" expect "linphonec>" send "quit\r" expect "Terminating..." exit Set execute permission on the file. I placed mine in /usr/local/bin chmod +x /path/to/file # e.g. chmod +x /usr/local/bin/ Now you can execute your wrapper from a script like this and it will send the message to your sip address. Change the path to the location of your wrapper script. /usr/local/bin/ "this is a sip message"
  11. Yesterday i did install Armbian_5.86_Aml-s905_Debian_buster_default_5.1.0_20190514.img from @balbes150 on my Sunvell T95KPro (S912). While installing Pihole the Installation does break when trying to start lighttpd. After checking with journalctl -u lighttpd it turns out that the file /usr/share/lighttpd/ is missing, because in the newer lighttpd-version of debian buster the file has be renamed to /usr/share/lighttpd/ (see also ) Pihole doesnt know/use the new name with debian buster, so it fails to start the lighttpd So I did find 2 ways to resolve the problem. First (quick and dirty?) way: cp /usr/share/lighttpd/ /usr/share/lighttpd/ or ln -s /usr/share/lighttpd/ /usr/share/lighttpd/ read also: Pihole breaks lighttpd on Debian Buster #2557 the second way (found it at ) is to edit /etc/lighttpd/lighttpd.conf and search for the 2 following lines and comment them out (found the 2nd one at the end of the file): #include_shell "/usr/share/lighttpd/" #include_shell "cat external.conf 2>/dev/null" and add the follwoing line to the file: include_shell "/usr/share/lighttpd/" After saving the file you should be able to restart lighttpd via sudo /etc/init.d/lighttpd restart or sudo service lighttpd restart or sudo service lighttpd stop sudo service lighttpd start BUT second way does not work good with updating or repair-install of pihole, because I think this will set the config-file to the old state (also for server.error-handler-404) So maybe the first way will work better while pihole doenst know the new file-name - or you also can do both ways BTW: If you are experience a 400 Bad Request while only using the IP for getting to the Pihole-Webpage (and the redirect should ask you if you want to use the /admin page - but it doenst) then try the follwing small resolution - edit a line in the file /etc/lighttpd/lighttpd.conf from: server.error-handler-404 = "pihole/index.php" to: server.error-handler-404 = "/pihole/index.php" lighttpd.conf
  12. Maybe someone here knows the 8-Bit Guy and the project of his Dream-Computer - the Commander X16 You could see the actual state of the real hardware at YT-Video from the 8-Bit Guy: (Building my Dream Computer - Part 2) Since the hardware isnt ready/completed yet there is a Emulator which uses SDL2 and can be compiled now (since r30) also on Linux ARM Github-page of the emulator: Source: or Linux-Binary for PC including the 2 ROMs: libsdl2-dev hasnt to be compiled from source for armbian, because we have already a installable package and the runtime libsdl2-2.0-0 is already installed in the desktop image. For compiling the Emulator I used on my NanoPi K1 Plus a fresh compiled (with armbian-build-system) dev-image: Armbian_5.97_Nanopik1plus_Debian_buster_dev_5.3.0-rc8_desktop For to have all programs for compiling the application I did use sudo apt install gcc git make libsdl2-dev zip unzip -y Then we do create a directory and download the source and extract it: mkdir x16 cd x16 wget tar -xvf r30.tar.gz Now we change in the newly created directory and do compile with make: cd x16-emulator-r30/ make For running the emulator we do need the 2 ROMs chargen.bin and rom.bin out of the archive in the same directory as the compile x16emu binary. Now we can run the emulator (here with german keymap): ./x16emu -keymap de Unfortunately the emulator doesnt run very fast, do use only one CPU-core and hasnt idle-support - so the CPU will get really fast very hot (70 Degree). A AMD Phenom II X4 with 4x3GHz max. is about 2 times more faster (100%+200%=300%) than the X16 on the NanoPi K1 Plus
  13. For those who like to monitor temperature. Connect SDA & SCL to pins 3 and 5, connect 3.3V and GND. Connect all address wires of the DS1621 to ground. # sudo apt install i2c-tools # echo ds1621 0x48 >/sys/class/i2c-adapter/i2c-1/new_device# cat /sys/devices/platform/ff140000.i2c/i2c-1/1-0048/hwmon/hwmon0/temp1_input Optional, use lm-sensors: # sudo apt install lm-sensors # sensors Optional, temperature logging: Create a file with the following contents: #!/bin/bash echo "`date +%Y-%m-%dT%R`;`cat /sys/devices/platform/ff140000.i2c/i2c-1/1-0048/hwmon/hwmon0/temp1_input`" >>/home/USER/temp Add an entry to /etc/crontab: 0 * * * * USER /home/USER/ And restart cron or your box for logging every hour. Thanks to Hope it's useful for someone!
  14. Panfrost instructions Armbian This tutorial explains how to build an Armbian image with panfrost. And what else you need to make it work. These are early drivers. Many things don't work yet. Only OpenGL 2.1 works now. You need to build an image with kernel 5.2 or later. For this you need an x86 pc with Ubuntu 18.04 or a virtual Ubuntu 18.04 x86 image. First install git, then clone the build folder from Armbian, and enter the build directory. apt-get -y -qq install git git clone --depth 1 cd build Now run the script with EXPERT=yes so you can choose to build a dev image. sudo ./compile EXPERT=yes Choose "Full OS image for flashing" Then "Show a kernel configuration menu before compilation" Choose your board. If it's not in the regular list, look in "Show SCS/WIP/EOS/TVB". Choose Development version kernel configuration -> device drivers -> graphic drivers -> panfrost Let it run until it's finished. The image will be in the /build/output/images Burn it to an SD-card/eMMC/... Now we need to install all the needed software sudo apt install flex bison python3-mako libwayland-egl-backend-dev libxcb-dri3-dev libxcb-dri2-0-dev libxcb-glx0-dev libx11-xcb-dev libxcb-present-dev libxcb-sync-dev libxxf86vm-dev libxshmfence-dev libxrandr-dev libwayland-dev libxdamage-dev libxext-dev libxfixes-dev x11proto-dri2-dev x11proto-dri3-dev x11proto-present-dev x11proto-gl-dev x11proto-xf86vidmode-dev libexpat1-dev libudev-dev gettext glmark2 glmark2-es2 mesa-utils xutils-dev libpthread-stubs0-dev ninja-build bc python-pip flex bison cmake git valgrind llvm llvm-8-dev python3-pip pkg-config zlib1g-dev wayland-protocols Download and install meson wget sudo dpkg -i meson_0.52.0-2_all.deb Download and install mesa DRM git clone git:// cd drm meson build --prefix=/usr ninja -C build sudo -E ninja -C build install cd ..

  15. Hello everyone! Is there anyone who tried to run Docker on armbian? Ok, let's start from the beginning: I am from the Hypriot Team (we made Docker available on ARM) and recently saw some guys successfully playing with Docker on armbian. Meanwhile, we know, that our Docker runs at least on the Cubietrack and Lamobo R1/BananaPi R1 on top of armbian! This is awesome because, you know, IoT is coming, and Docker on ARM helps get a grip on many challenges induced by IoT. However, we were only able to support Docker on Raspberry Pis so far... Imagine if Docker would run on more than just a few ARM boards! Armbian seems an awesome platform to extend the family of Docker compatible boards. So, I wonder if there is anyone who tried to run Docker on armbian? If you are now curious about this topic and wanna get started, please see this blog post of how to install Docker on ARM within no time: Looking forward to get in touch with you guys!
  16. Hi all. I've made a new video about how to build your own Armbian image with the Armbian build script. I also show how to set up virtualbox with a Ubuntu 18.04 image. Here's the video. Greetings, NicoD
  17. Hi all. I've made a new noob video on how to install Armbian on an SBC. I also show how I set up my Armbian desktop. And I show how to install Armbian onto another media. Greetings, NicoD
  18. How to install Puppeteer on node.js on Armbian. Tested on OrangePi Zero Plus running Ubuntu Xenial or Bionic. Should work on other boards and other builds. How to install the latest version of node.js. (at the time of writing was 12.7.0). Instructions for installing node.js on Debian and Ubuntu can be found at: The instructions at the time of writing were: # Using Ubuntu curl -sL | sudo -E bash - sudo apt-get install -y nodejs # Using Debian, as root curl -sL | bash - apt-get install -y nodejs Both of these methods work on Ubuntu. If you then try to install Puppeteer using "npm i puppeteer" you will discover that the version of Chrome that it installs locally is for the wrong CPU architecture. The solution to the problem is to install and use puppeteer-core instead of puppeteer. When using puppeteer core, you must define the path to Chrome or Chromium in the puppeteer script (see the test example below). First install a recent version of Chromium Browser. This will be used in headerless mode. apt-get install chromium-browser When the chromium-browser install is complete Create a folder for your Puppeteer project Let's assume that your folder is in /mnt/data/nodejs-scripts/screenshot (mine was on a mounted ntfs drive). cd /mnt/data/nodejs-scripts/screenshot npm init -y npm i puppeteer-core --save Now create a node.js test script Lets say that you call it screenshot.js Using your favorite editor insert the following lines into the file. const puppeteer = require('puppeteer-core'); (async ()=>{ const browser = await puppeteer.launch({ executablePath: '/usr/bin/chromium-browser', args: ['--no-sandbox'], headless: true }); const page = await browser.newPage(); await page.goto(''); await page.screenshot({path: 'screenshot.png'}); await browser.close(); })(); Make the script executable. chmod +x screenshot.js You can now run the script cd /mnt/data/nodejs-scripts/screenshot nodejs screenshot.js If it has worked, you will find a screenshot of the DuckDuckGo page in your project folder.
  19. Hi all. I've made a new video about x11vnc. With this you can control your Linux desktop from any other PC/SBC. It even works for videos and games. Only there's no sound. I use lightdm as display manager. If you use another display manager, change the line "After=lightdm.service" with your display manager. Here's my video, To Install sudo apt install x11vnc To create a password file x11vnc -storepasswd The service script : /lib/systemd/system/x11vnc.service [Unit] Description="x11vnc" Requires=display-manager.service After=lightdm.service [Service] ExecStart=/usr/bin/x11vnc -auth guess -loop -forever -safer -shared -ultrafilexfer -bg -o /var/log/x11vnc.log ExecStop=/usr/bin/killall x11vnc [Install] Enable the service script sudo systemctl daemon-reload sudo systemctl enable x11vnc sudo systemctl start x11vnc greetings.

  20. Hello dear experts at Armbian well the mysql_connect_error-script is a great help: It returns a string description of the last connect error ( see more infos here: ). The mysqli_connect_error() function returns the error description from the last connection error, if there is any error-note. the return value are the following ones: a. A string that describes the error. b. an empty string if no error occurred. at least this goes for the Version: PHP 5, PHP 7 well - if we run the code below we can get the info bout the option to connect to the db. What if we run this as a mysql-test-script, and what if we will want to convert it to use mysqli? Can this be done by changing mysql _query($sql); to mysqli _query($sql); ? <?PHP // the test-script that we are running. $DB["dbName"] = "emails"; $DB["host"] = "localhost"; $DB["user"] = "root"; $DB["pass"] = ""; $link = mysql_connect($DB['host'], $DB['user'], $DB['pass']) or die("<center>Howdy - be aware; There a thing happenede - An Internal Error has Occured. Please report following error to the webmaster shot him a mail now.<br><br>".mysql_error()."'</center>"); mysql_select_db($DB['dbName']); // end header connection part // function from a functions file that I run a mysql query through in any page. function executeQuery($sql) { $result = mysql_query($sql); if (mysql_error()) { $error = '<BR><center><font size="+1" face="arial" color="red">An Internal Error has Occured.<BR> The error has been recorded for review</font></center><br>'; if ($_SESSION['auto_id'] == 1) { $sql_formatted = highlight_string(stripslashes($sql), true); $error .= '<b>The MySQL Syntax Used</b><br>' . $sql_formatted . '<br><br><b>The MySQL Error Returned</b><br>' . mysql_error(); } die($error); } return $result; } // example query ran on anypage of the site using executeQuery function $sql='SELECT auto_id FROM friend_reg_user WHERE auto_id=' .$info['auto_id']; $result_member=executequery($sql); if($line_member=mysql_fetch_array($result_member)){ extract($line_member); } else { header("location: index.php"); exit; } ?> If we do replace mysql_* with mysqli_* then we will have to bear in mind that a whole load of mysqli_* functions need the database link to be passed. E.g.: the following ones. mysql_query($query) becomes mysqli_query($link, $query) I.e., lots of checking required. on the other hand side: is it suffice if we replace every mysql_* function call with its equivalent mysqli_*, when we will use the procedural API (note: there is some code based on the MySQL API, which is a procedural one - at least afaik), To help with that, the The MySQLi Extension Function Summary-manual is definitely something that will prove helpful. We can do the following: we have the following options to do that: - mysql_connect will be replaced by mysqli_connect - mysql_error will be replaced by mysqli_error and/or mysqli_connect_error, depending on the context - mysql_query will be replaced by mysqli_query ,,,, and so on and so forth. Note: For some functions, we may need to check the parameters very very carefully: Maybe there are some differences here and there -- but not that many differences. Belive me. Both mysql and mysqli-codes are based on the same library ( the great and powerful libmysql ; at least for PHP-version <= 5.2) Usage - for instance: with mysql, we have to use the mysql_select_db once connected, to indicate on which database we want to do our queries mysqli, on the other side, allows us to specify that database name as the fourth parameter to mysqli_connect.
  21. Hello All After a lot of hours and sleepless nights I was able to get this 5" LCD to work with the BPI-M64 module. 1. Correct resolution setup + environment. A. In /Boot/armbianEnv.txt set the following: Make sure to enter overlays= spi-add-cs1 spi-spidev (this is for the touch panel to work) B. for 180 rotation: extraargs=fbcon=rotate:2 drm_kms_helper.edid_firmware=HDMI-A-1:edid/800x480.bin video=HDMI-A-1:800x480-24@60 No rotation: extraargs= drm_kms_helper.edid_firmware=HDMI-A-1:edid/800x480.bin video=HDMI-A-1:800x480-24@60 C. this info came from: by the way if you dont want to see the console messages during boot you can add this to the armbianEnv.txt: console=serial D. Save and close. E. Create a directory where the .desktop file will be contained: sudo mkdir -p /etc/xdg/autostart F. Create the .desktop file and make it executable: Let's call this file custom-screen-resolution.desktop: sudo nano /etc/xdg/autostart/custom-screen-resolution.desktop The content of the file custom-screen-resolution.desktop should look as: [Desktop Entry] Name=Custom Screen Resolution Exec=sh -c 'xrandr --newmode "800x480_60.00" 29.50 800 824 896 992 480 483 493 500 -hsync +vsync; xrandr --addmode HDMI-1 800x480_60.00; xrandr --output HDMI-1 --mode 800x480_60.00' Terminal=false Type=Application Categories=Application G. reboot H. After O/S is loaded go to settings => display and you be able to select the 800x480 resolution. 2. With the Touch Panel I lost some hair on my head since there were many issues to overcome. A. I had to solder the LCD TP_IRQ Pin (22) to unused Pin (13) since Pin 22 on the BPI-M64 didnt support GPIO to IRQ... and diving into the sources took a lot of time to figure out why, so the easiest way is to change the Pin. (please have a look at the attached picture. B. Also there were wrong settings in the sun50i-a64-spi-add-cs1.dtbo overly, it seems that CS1 were going to the wrong Pin ( not as the BPI_M64 page shows, it should have been going to Pin 26 - PC2 but in the overlay it did go to Pin 35- PB6) I really dont know why so I had to change the DTS file to: /dts-v1/; /plugin/; / { compatible = "allwinner,sun50i-a64"; fragment@0 { target = <&pio>; __overlay__ { spi0_cs1: spi0_cs1 { pins = "PD0"; function = "gpio_out"; output-high; }; spi1_cs1: spi1_cs1 { pins = "PC2"; function = "gpio_out"; output-high; }; }; }; fragment@1 { target = <&spi0>; __overlay__ { pinctrl-names = "default", "default"; pinctrl-1 = <&spi0_cs1>; cs-gpios = <0>, <&pio 3 0 0>; /* PD0 */ }; }; fragment@2 { target = <&spi1>; __overlay__ { pinctrl-names = "default", "default"; pinctrl-1 = <&spi1_cs1>; cs-gpios = <0>, <&pio 2 2 0>; /* PC2 */ }; }; }; The sun50i-a64-spi-add-cs1.dts & the sun50i-a64-spi-add-cs1.dtbo are also attached. Just replace the sun50i-a64-spi-add-cs1.dtbo located at /boot/dtb/allwinner/overlay with file that I have attached here. C. The next settings I have found at post here I just copy and paste so you will have all the info in one page: D) Download ads7846? touch driver (compatible with xpt2046) mkdir ds7846 cd ds7846 wget mv ads7846.c?format=raw ads7846.c E) Create a makefile (Take note that it is TABS instead of spaces before the $(MAKE)) nano Makefile Insert the below in without the ----- -------------------------------- obj-m := ads7846.o KDIR := /lib/modules/$(shell uname -r)/build PWD := $(shell pwd) all: $(MAKE) -C $(KDIR) M=$(PWD) modules clean: $(MAKE) -C $(KDIR) M=$(PWD) clean install: $(MAKE) -C $(KDIR) M=$(PWD) modules_install -------------------------------- F) Exit nano and run the following cd /usr/src/linux-headers-4.19.38-sunxi64 make scripts make modules_prepare sudo make sudo make install sudo depmod G) Download and compile and install ads7846_device cd .. git clone cd fbtft_tools/ads7846_device make sudo make install sudo depmod H) Load ads7846 and ads7846_device on boot sudo nano /etc/modules-load.d/ads7846.conf ads7846 ads7846_device I) Load ads7846_device options nano /etc/modprobe.d/ads7846_device.conf options ads7846_device model=7846 cs=1 gpio_pendown=234 keep_vref_on=1 swap_xy=0 pressure_max=255 x_plate_ohms=150 x_min=3900 x_max=200 y_min=3900 y_max=200 busnum=1 Note: GPIO_PENDOWN relate to the GPIO of the actual Pin number 13, With my board it is 234, If you are using other module (not BPI_M64) it could be other number, check with your module documents or do "gpio printall" in your board to see the correct Pin number. Since I use the screen in inverted mode those settings fits my needs. if you will use it in normal mode you might have to switch those parameters : swap_xy=0 or 1 x_min=3900 x_max=200 y_min=3900 y_max=200 or x_min=200 x_max=3900y_min=200 y_max=3900 I didnt really need it but you can install sudo apt-get install xinput-calibrator for fine tunning. (follow the instructions) I hope that I didnt forget anything. By the way the kernel I use is: 4.19.38-sunxi64 sun50i-a64-spi-add-cs1.dtbo sun50i-a64-spi-add-cs1.dts

  23. This weekend I was revising and testing the OV5640 for some A64 boards. To enable the Camera (OV5640) on NanoPi A64 for the mainline kernel you have to update the following: * DT * GPIO-I2C Here is the excerpt : Kernel config: CONFIG_I2C_GPIO=m CONFIG_VIDEO_OV5640=m CONFIG_VIDEO_SUN6I_CSI=m
  24. Hi all. I've done a lot of tests with different desktop environments on Armbian. I wanted an as light as possible desktop environment so I'd have enough ram left to do video rendering with the NanoPi M4(2GB) I had to try a lot of things to get things working fine. So I wanted to save others that hassle. Setting up Display Manager First we need a Display Manager. NODM is installed by default. I tried lightdm but couldn't get it to work. So I went for LXDM. With NODM installed I had problems, so I also removed NODM. To be sure lxdm is configured right, I also manually configure it. sudo apt install lxdm sudo apt remove nodm sudo dpkg-reconfigure lxdm Install LXDE Desktop Next step is to install the desktop environment you want. There is a problem with some Desktop Environments and LXDM what makes you can't login to some DE's out of the box. That we will resolve later. Easiest is to install lxdm first to be able to configure the others well. And reboot. sudo apt install lxde sudo reboot Once booted you should be greeted by the Login screen. Here you can choose your different Desktop Environment. Choose LXDE and login. If you'd try xfce4, then you'd see it doesn't work. To fix this we need to change the file /usr/share/xsessions/xfce.desktop. Use your favorite text editor. I use geany. sudo geany /usr/share/xsessions/xfce.desktop Somewhere at the top of the file you'll see "Name=Xfce Session". Replace that space with a hyphen to "Name=Xfce-Session" and save the file. Now you can also login to the default XFCE4 Desktop. With other desktops this can be the same. Go the the same directory and open the file with the desktop name that doesn't work. Again replace the space with a hyphen Installing different Desktop Environments. For the Mate desktop I also needed to install the applets, else I got errors at login because of these missing applets sudo apt install mate-desktop-environment mate-applets For KDE-Plasma sudo apt install kde-full For Gnome. Modify the file sudo geany /usr/share/xsessions/gnome... sudo apt install gnome-session sudo update-alternatives --config gdm3.css I also tried LXQT. But this one didn't work. You can try others too. Remove Desktop Environment To remove a desktop environment you don't want anymore you do the remove instead of install. sudo apt remove kde-full sudo apt remove mate-desktop-environment . . . Please let me know if there's mistakes made, or if you've got advice. Source for changing the name to make them work @IgorS : Greetings, NicoD
  25. I need a suggestion for a samba server (guess that is what it is called). I have an 8 TB external powered HD, and need a device that I can attach it to, so I can "see" it on the network. I had it attached to the USB 3 port on my Asus router, but it had issues, because the router did not support the 8 TB HD. I now have it connected to one of my microPCs (Tronsmart Ara X5) USB 3 ports, but I am only gettting a max of 12 MBs speed. I would like an inexpensive board that will support that drive and is easy to set up as a samba server..... thanks.
