I made this simple dts file for my GPS NTP server running on Zero2/3 and Zero2w On Zero2, use PC9 as PPS in , and on Zero2W use PI5 . It should be configured in /boot/armbianEnv.txt, but I unsuccess on zero2w, so you must comment out two lines and compile it by yourself. Maybe help someone. sun50i-h616-pps-gpio.dtso

Hello, I have a new LCD which I believe is an ili4988 (although the vendor says ili9486 and st7796) https://www.aliexpress.us/item/3256803856059047.html I have read somewhere, that I can use an ili9341 spi driver, only by changing the resolution and changing the initialization script. I looked in the waveshare website and github, they don't have anything for the ili9488 Then, I found some arduino code in http://www.lcdwiki.com/3.5inch_SPI_Module_ILI9488_SKU%3AMSP3520 (look for the "3.5 inch SPI Module Package(ILI9488)" link, then find the LCDWIKI_SPI.cpp The initialization sequence is in line 1697: I am currently trying to convert it to a DTS-format init string, so that it fits my ili9341-fb.dts, which I made earlier this year: I am unsure how to start the init line, can someone help me? Then, when I have that init string confirmed, I can use: https://github.com/notro/panel-mipi-dbi/wiki https://blog.csdn.net/CNflysky/article/details/125171176 To switch to the mipi-dbi driver, which would get me DRM (instead of FB)

I’m running Armbian debian minimal image on my Orange Pi Zero 3, using the onboard WiFi (wlan0) with the unisoc_wifi driver. The WiFi consistently drops with logs like these: [ 11.048517] unisoc_wifi wlan0: mixed HW and IP checksum settings. [259241.515808] unisoc_wifi wlan0: sprdwl_report_connection Asus failed status code:30! [345665.483530] unisoc_wifi wlan0: sprdwl_report_connection sm_state (5), status: (2)! [345665.483567] unisoc_wifi wlan0: sprdwl_report_connection Asus failed status code:1! NetworkManager also reports: link timed out. Activation failed for connection 'Asus' After the crash, restarting NetworkManager doesn’t resolve the issue. Trying modprobe -r unisoc_wifi fails, saying the module is not found. The only way to fix it is to reboot the system. My USB WiFi dongle works fine without these issues, so it seems specific to the onboard WiFi. Has anyone else experienced this or found a solution for this driver? I'm getting to the point I'm going to write a cron job when the network drops to reboot the machine 🙃

I am experimenting with a cheap ILI9341 screen and mi OrangePi Zero LTS https://www.aliexpress.us/item/2251832431328471.html I found these recent instructions to be able to display graphics here: https://ryjelsum.me/homelab/xpt2046-ili9341-opi-zero/ with a reference to a previous experience (without mentioning success) https://hackaday.io/project/190371-g-edm/log/217902-first-success-with-armbian-nanopi-and-ili9341-touch and independently, I found these instructions and experiences here: https://docs.armbian.com/User-Guide_Allwinner_overlays/ https://forum.armbian.com/topic/27457-connecting-banana-pi-m2-zero-with-ili9341-display-over-spi-on-latest-armbian-image/ <-just found it and it has some success with BananaPi M2 Zero https://tech-de.netlify.app/articles/de547180/index.html https://4pda.to/forum/index.php?showtopic=782242&st=5060#entry112401076 I connected with wires as shown in instructions: https://forum.armbian.com/topic/28674-text-version-of-orange-pi-zero-pinout/ And the LCD's LED input pin to 3.3V I activated the spi-add-cs1 overlay in arbian-config I copied the dts for opiZ into ~/ili9341/ili9341-touch-double-spi-cs.dts Then, I executed: cd ili9341 armbian-add-overlay ili9341-touch-double-spi-cs.dts Then, I rebooted, and my LCD just looks gray.

Should I downgrade to Linux 6.1.53?

I'm trying to configure the CS (Chip Select) pin on my Orange Pi Zero 3. I added overlays=spi-spidev to the /boot/armbianEnv.txt file, created my own dtbo file, and tried all possible methods suggested by ChatGPT. I've been struggling for two weeks with no success. I haven't been able to switch the CE1 pin to alt4 state; it only stays off, nothing else. Is it even possible to work with SPI on this board?

I see the device tree file here: ``` /boot/dtb/allwinner/overlay/sun50i-h616-uart5-ph.dtbo ``` But after adding `overlays=uart5-ph` to `armbianEnv.txt` and rebooting, I'm not getting any new serial device created. Any idea what I need to do?

Hello First, sorry for my English Second, the problem... I have an Orange PI Zero 3, 4gb I install the OS without any problem, the image I use is the following: "Armbian_23.08.0-trunk_Orangepizero3_bookworm_current_6.1.31-1GB-2GB.img" I configure the network with the program "nmtui", everything is fine. I enter through ssh since the screen is not detected through HDMI, I do an apt update and then apt upgrade... everything seems correct, until I do a reboot... my Orange Pi does not start anymore. I am interested in installing openmediavault, that is why I resort to a debian image. What is the problem? I am not using the correct image? I need your help

Look at the description https://docs.armbian.com/User-Guide_Armbian_overlays/ when I set UART I2C in armbianEnv.txt it should be overlay_prefix=sun50i-h616 overlays=i2c3-ph uart5-ph as described on the given page But when I use armbian-config and go to Manage Overlays my settings are not seen and I have to set them but the names of all overlays are preceded by the prefix. After selecting and saving the settings in armbinEnv.txt it is overlay_prefix=sun50i-h616 overlays=sun50i-h616-i2c3-ph sun50i-h616-uart5-ph as a result the defined overlays are not loaded Is it supposed to be like this? I use OrangePi Zero 3 with updated system Welcome to Armbian_community 25.2.0-trunk.331 Bookworm Kernel Linux 6.6.70-current-sunxi64

I built Armbian Edge from source (bookworm, server, no gui) and have no video via HDMI. Being a new build, networking is not set up and so I cannot SSH in to troubleshoot. I reverted to a stable Armbian build on another SD, upgraded that kernel to Edge, and lost video output. This one already has networking set up, I can SSH in, but I don't know what to look for in order to get my monitor working. Goal being, figure out what needs changed, and change it in the build process for a new image. I appreciate any pointers.

Hi, I got my OPiZ3 2GB model last week, but it seems to detect as 4GB sometimes. At first, I thought I got lucky and the seller shipped the 4GB model, but I realized it crashes under load when it do. and I have to restart multiple times to get it right. The issue shows up in htop and free, where it reports double the memory and swap. I’m using the Minimal/IOT image with Armbian Linux v6.6. Here's the output from armbianmonitor -u: https://paste.next.armbian.com/iguzunaved The MemTotal value switches between 4GB and 2GB. Any ideas on how to fix this? Thanks!

I know I need to find out which drivers to use... I just don't know where to start, I know I've seen some people having success with these displays - ili9488, and a couple others - I just don't know if this fits one of those overlays or not. (nothing I've tried so far has worked). Any help identifying and pointing in the right direction, I would greatly appreciate. Trying to get this to work on my Orange Pi Zero 3 4gb. (uploading images has failed.... so I guess I'll link them?) https://imgur.com/a/NORYCj7 *edit 12/21 - renamed topic since I've Identified the display, going to track my (our?) progress with trying to get it to work.

Guys i have an orange pi zero 3 with 4GB RAM running a tiny proxmox 8.3.2 and everything was ok, i used the ./compile.sh command in /build to create a custom kernel with KVM enabled to get this to work a few months ago, now i have updated the system but the kernel installed has no support for KVM, obviously i want to use the standard procedure to recompile the kernel re-enabling the KVM but i dont know how, i know there is a way to pass commands to ./compile.sh but from what i have seen i dont know where or how to pass to the program the fact that i want KVM support enabled, i have seen things like this: apt -y install git git clone https://github.com/armbian/build cd build ./compile.sh \ BOARD=orangepizero \ BRANCH=default \ BUILD_DESKTOP=no \ KERNEL_ONLY=yes \ KERNEL_CONFIGURE=yes but how do i tell this to let me use KVM? is this even correct? cos the docs wont explain exactly HOW to create only the new custom kernel and update it, without having to rebuild everything from zero, it seems that in the past the docs had info about this but now the docs wont tell me anything, i know it is a very noob question but if someone could guide me please.

Hi. I'm running Armbian Distro Debian 12 Minimal/IOT with Gnome GUI on an Orange Pi Zero3 2gb and 4gb models. I installed XRDP Xorg to be able to access from Windows 10. I can access the systems remotely, but both machines turn off after a short period of activity, somewhere between 5-10 minutes, whether they're idle or performing some activity. I've already looked for some hibernation/suspend option, but I only found something related to turning off the screen, which didn't solve the problem after being disabled. The Orange Pi Zero3 2gb machine ran for a few months using another version of Armbian recommended by the manufacturer's website without this problem occurring. The 4gb machine, even using the version recommended on the manufacturer's website, has always had this problem. Is there anything I can try to find out what's causing this problem?

I’ve been running Armbian from an SSD for a while using this guide: https://jamesachambers.com/orange-pi-zero-2-usb-ssd-boot-guide/ Recently, after running apt update && apt full-upgrade, the following issues have occurred: 1. Wi-Fi adapter is no longer detected. 2. CPU utilization exceeds 80% when accessing the Gnome launcher or starting GUI apps (e.g., a web browser, even without opening a webpage). 3. The system becomes laggy and nearly unusable, noticeable when moving the mouse. Are there recent changes to Armbian that affect SSD booting? Is there a workaround for these issues?

I suddenly have a need to test Linux 6.11 or greater, because there's a needed improvement in the panel-mipi-dbi-spi driver (thread keyword ili9488) User "The Going" has kindly advised me to try his Armbian branch with Linux 6.12, so I am here sharing results as I test it with my Orange Pi Zero 3. Initial instructions: https://forum.armbian.com/topic/35635-armbian-242-is-broken-on-orange-pi-pc2/#findComment-207980 At first try, I decided to NOT follow this step: armbian/build> egrep '^-' patch/kernel/archive/sunxi-6.12/series.conf (finds all the excluded patches) Well, I continued. Choosing Linux Edge, shallow option, Bookworm minimal, there were zero problems: no patching errors and no compilation errors. At the end of the 4 hour compilation, I tested the resulting image in my Orange Pi Zero 3... and it booted fine. Not working at this moment: wifi (#iw dev returns nothing) spi1 (failed on fdt_overlay_apply(): FDT_ERR_NOTFOUND when I use a dts overlay that works in Linux 6.7) usb (lsusb only shows the 2 root hubs, but not my usb devices) when I decompile sun50i-h618-orangepi-zero3.dtb there is no references to spi1 or hdmi (maybe more) Working: serial console ethernet other things not tested Next, I am going execute armbian/build> egrep '^-' patch/kernel/archive/sunxi-6.12/series.conf and find specific patches that maybe will improve my hardware situation. Result of that egrep search command, with patches I will try first, one by one, in bold

I'm looking to build an ntp server using the OrangePi Zero 3 and I noticed there is no pps-gpio device tree overlay for the h616 chipset only the h5 chipset. Has anyone created a custom dt overlay? Thanks in advance.

Hi there, recently I bought an Orange Pi Zero3 with 1GB RAM. I want to connect a 20*4 character LCD display(https://www.tinytronics.nl/en/displays/lcd/lcd-display-20*4-characters-with-white-text-and-blue-backlight-with-i2c-backpack) to it. I have previously used this display with Arduino UNO, which worked great. Now I want to use it with the Orange Pi Zero3 (Ubuntu 24.04). I have no experience with the Orange Pi or single-board computers in general. I followed some tutorials, but I couldn't make it work. I did this: Wiring: I2C Backpack Orange Pi Zero3 VCC Pin 2 GND Pin 6 SCL Pin 5 SDA Pin 3 Terminal: sudo apt-get install -y python-smbus i2c-tools user@orangepizero3:~$ sudo i2cdetect -y 0 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- UU -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- user@orangepizero3:~$ sudo i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: 30 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- UU -- -- -- -- -- -- -- 50: 50 -- -- -- 54 -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- It seems like the display cannot be found. How can I fix this?

I had an OrangePi Zero LTS and set up an access point using the following commands: % sudo apt install dnsmasq-base -y % sudo sed -i "s/#MulticastDNS=no/MulticastDNS=yes/g" /etc/systemd/resolved.conf % sudo nmcli connection add type wifi ifname wlan0 con-name access_point autoconnect yes ssid <ssid> % sudo nmcli connection modify access_point 802-11-wireless.mode ap 802-11-wireless.band bg ipv4.method shared % sudo nmcli connection modify access_point connection.mdns 2 % sudo nmcli connection modify access_point wifi-sec.key-mgmt wpa-psk % sudo nmcli connection modify access_point wifi-sec.psk "<password>" % sudo nmcli connection up access_point % sudo hostnamectl set-hostname <hostname> This worked fine, I can connect and ssh using `hostname.local` etc etc I recently just got a OrangePi Zero 3 and tried the minimal OS, I did the commands above along with: sudo apt install network-manager -y The access point does seem to appear and I can see it from phones and laptops etc but I can't connect to it. What is the best way to debug the issue? This is what it shows from the following commands: $ nmcli device DEVICE TYPE STATE CONNECTION wlan0 wifi connected access_point lo loopback connected (externally) lo p2p-dev-wlan0 wifi-p2p disconnected -- end0 ethernet unmanaged -- $ nmcli connection NAME UUID TYPE DEVICE access_point d7a42b9e-63bd-4e76-9457-018cbd43d712 wifi wlan0 lo a0764323-619d-4bd9-b029-fa8da5ed24c4 loopback lo Any help is appreciated! I should mention that the OrangePI Zero LTS OS wasn't the minimal one it was the server one so I'm not sure if I'm just missing something in the minimal OS for OrangePi Zero 3. I get these debug logs if I try and connect to the access point: Sep 29 13:41:35 <hostname> NetworkManager[846]: <debug> [1727613695.7400] ndisc-lndp[0xaaaae75732f0,"wlan0"]: processing libndp events Sep 29 13:41:35 <hostname> NetworkManager[846]: <debug> [1727613695.7409] platform: (end0) signal: address 6 changed: fd00::97ff:fe9b:cbc0/64 lft 7200sec pref 3600sec lifetime 1394-1394[3600,7200] dev 2 flags mngtmpaddr,noprefixroute src kernel Sep 29 13:41:35 <hostname> NetworkManager[846]: <debug> [1727613695.7412] platform: (end0) signal: address 6 changed: fd00::5bc2:4133:f0ea:931d/64 lft 7200sec pref 3600sec lifetime 1394-1394[3600,7200] dev 2 flags secondary src kernel Sep 29 13:41:35 <hostname> NetworkManager[846]: <debug> [1727613695.7441] manager: (end0): assume: don't assume because device is not managed Sep 29 13:41:40 <hostname> NetworkManager[846]: <debug> [1727613700.3462] ndisc-lndp[0xaaaae75732f0,"wlan0"]: processing libndp events Sep 29 13:41:40 <hostname> NetworkManager[846]: <debug> [1727613700.3471] platform: (end0) signal: address 6 changed: fd00::97ff:fe9b:cbc0/64 lft 7200sec pref 3600sec lifetime 1398-1398[3600,7200] dev 2 flags mngtmpaddr,noprefixroute src kernel Sep 29 13:41:40 <hostname> NetworkManager[846]: <debug> [1727613700.3474] platform: (end0) signal: address 6 changed: fd00::5bc2:4133:f0ea:931d/64 lft 7200sec pref 3600sec lifetime 1398-1398[3600,7200] dev 2 flags secondary src kernel Sep 29 13:41:40 <hostname> NetworkManager[846]: <debug> [1727613700.3499] manager: (end0): assume: don't assume because device is not managed Sep 29 13:41:44 <hostname> NetworkManager[846]: <debug> [1727613704.8566] ndisc-lndp[0xaaaae75732f0,"wlan0"]: processing libndp events Sep 29 13:41:44 <hostname> NetworkManager[846]: <debug> [1727613704.8575] platform: (end0) signal: address 6 changed: fd00::97ff:fe9b:cbc0/64 lft 7200sec pref 3600sec lifetime 1403-1403[3600,7200] dev 2 flags mngtmpaddr,noprefixroute src kernel Sep 29 13:41:44 <hostname> NetworkManager[846]: <debug> [1727613704.8578] platform: (end0) signal: address 6 changed: fd00::5bc2:4133:f0ea:931d/64 lft 7200sec pref 3600sec lifetime 1403-1403[3600,7200] dev 2 flags secondary src kernel Sep 29 13:41:44 <hostname> NetworkManager[846]: <debug> [1727613704.8603] manager: (end0): assume: don't assume because device is not managed
