Good afternoon! Tell me about the case, please, the post is great, but maybe I'm initially going the wrong way. Initial task: data exchange between a remote server and equipment with a USB interface and CDC RS-232 or HID protocols. Putting a computer / laptop next to it is not an option. I did not find any ready-made solutions, there are only options: 1. Single board computer. Fast, cheap, angry, easy to make a case and PoE power from ready-made components on the market. 2. Arduino - to assemble from prototyping boards is long, difficult and expensive. To develop something of my own - the navel will be untied with my knowledge. 3. Hardware "extension" USB over TCP / IP - expensive, redundant. 4. Ready-made USB print server / router - can you easily write your own firmware? I read that OpenWrt is installed on TP-Link TL-MR3020 ... I am leaning towards the first option with a single-payer based on a combination of factors - complexity, price, availability, etc. Question on the topic. If you choose a single boarder, is it possible to implement booting from an ISO image on an eMMC partition or SD card? How do I do it on industrial PC x86 architecture: 1. I deploy Linux in the usual way (in my case I use Debian) on the master computer. 2. Create an ISO image (snapshot) using Linux Live Kit (Tomas-M). 3. I mark up disks on working computers, install GRUB, copy the prepared ISO image and tell the bootloader to boot from it. Profit. We have a "firmware" version of the download. You need to update the operating system or programs - we do this on a master computer, create a new ISO image and simply copy it to all other working computers. On single-payers, I read, U-Boot is used mainly, but he does not know how to do this. but it seems like it is written that he can boot GRUB for the second time, which can already boot ISO ... Who has any thoughts?

Hello. I have this old rk3188 based board with 32gb rom 1gb ram. The arduino is attached for console output. I wanted to install linux in it so i flashed rk3188 armbian to my sd card and it was able to boot up from sdcard successfully. But there is no hdmi signal. I tried to modify dtb file extlinux.conf file but it didnt work. Can anyone figure out what is the problem?

Hi all. Here my video about the MangoPi MQ-Pro. It's not powerful, not cheap and not great at anything. But it is nice to see it works. Everybody started out as a baby. So it now needs to grow.

What is the baud rate of s905w

Hi, I need to install kernel headers to build a wifi driver. Using armbian-config to install the headers does not work ... After much searching came across a logical suggestion - i.e. install the 'linux-headers-current-sunxi' package ... When I install that package (on a fresh 22.08.1install), the package installed is for 22.05.03 ... which is, er, the wrong version? Where do I find the headers for 22.08.1 ? Many thanks!

it does not exit the location screen. it doesn't go into anything. can anybody help me.

I'm thinking of buying a WindowsCE/Android Netbook that uses a WM8650 processor and want to install Linux on it but the only images I could find were 10 years old ;/ If a stock image won't work then how hard would it be to compile it for the WM8650? I'm a complete newbie so please explain as if I'm a kindergarden dropout :)

K-worker takes 10-20 % of one cpu core with later kernels. Does the 4.17 kernel still have this problem? Or is bionic a solution?

Hello. I installed armbian (22.05 jammy) on my banana pi m1 (original model). Since it doesn't come with onboard wifi, I decided to attach wifi dongle which uses RTL8188EUS chip. However, although i see it is recognized as "realtek ~~ RTL8188EUS network adapter" when i type 'lsusb' command, it doesn't show up as 'wlan0' when i enter 'ifconfig -a' command. What can I do to make the module work again?

Not that I ever got this working correctly on Raspbian, but how do I go about requiring a password for sudo? I am able to change the password via 'sudo passwd' without error, but I still don't know how to make the system request the password every time I sudo. Thanks so much Joe

Good morning, I'm using RK3328 SOM-EVB by Olimex with Armbian 22.02.0-trunk with Linux 4.4.213-rockchip64. I'm using it with an HDMI LDC 7" capcaitive touchscreen by Waveshare (https://www.waveshare.com/product/displays/lcd-oled/lcd-oled-1/7inch-hdmi-lcd-h.htm). I can't rotate the LCD in portrait mode. In Application->Screen the "Rotation" section is "none" and there aren't any other choice (like left, right, inverted). If in command line I use: xrandr --output HDMI-1 --rotate left it gives me back: xrandr: output HDMI-1 cannot use rotation "left" reflection "none" Does anybody knows how to solve it and rotate the LCD? Thanks

can someone tell me which board hardware supports video decoding with armbian? preferably with (C)VLC? Thanks a lot for your help!

Hi, since today the torrent downloader script "seed-armbian-torrent" on my seedbox fails to download the current "all-torrents.zip" from: https://dl.armbian.com/torrent/all-torrents.zip I then opened the link in my browser and I got a certificate warning (see attached). It seems the certificate for https://dl.armbian.com/ expired on 21. May 2022. Can someone confirm this, or is it an error on my end?

Hi! I am creating an Image that uses Cloud Init for customization. It involves creating an extra vfat partition for the CloudInit meta data. This is becoming an industry standard way to initialize virtual machines and now physical too. MAAS and Ubuntu on RPI also use it. What is the cleanest way to remove or disable equivalent scripts in Armbian ? In particular firstlogin and firstboot ?

Hello In raspberry pi there is an option to add a boot splash screen, looking in this forum I havent found and instructions or if it is even possible. I am not interested with u-boot splash screen but when the Linux start booting. I am using 3.5" SPI LCD and I do see the boot logs when the Linux is loading. So my question is if there is any guide of how to do that boot splash screen in Armbian or there is no way to do that?

Hey guys, I'm trying to find a way to read the values of the LRADC0 and LRADC1 of the A20. Those ADC are usually used for android-style buttons (labeled "VOL+", "VOL-", "MENU", "SEARCH", "HOME", "ESC" and "ENTER") which are connected to a low-resolution ADC via a resistor network. But I want to use the ADC for another purpose and I just need to read values between 0 and 63. Now it seems there is already a driver which let you setup the android-style buttons in the DTS (as can be seen in this patch) But I can't find the code of this driver, which I could use as a template. Any idea how to find the driver ? Or on how to read the LRADC values from a python script directly? Thanks! Related, for reference : https://www.olimex.com/forum/index.php?topic=4281.0 https://www.olimex.com/forum/index.php?topic=2425.0 Edit: I think I found the driver : https://github.com/torvalds/linux/blob/master/drivers/input/keyboard/sun4i-lradc-keys.c To be continued.

Hello, I just received this watch less than 24 hours. When I receive or making call with my ticwatch 2, the other party can't hear me at all. I can hear them clearly from the speaker. I can use the watch mic for voice typing and etc hence it is not hardware problem. My phone is Galaxy Note 4 running on Android 6.0.1 My ticwatch 2 is running on tic4.13.0 intl It is a nice watch so far and I would much appreciated if someone knows how to fix this issue.

If somebody has a chance to test new firmware blob for XR819 feedback would be appreciated Simply grab the code { font-family: Consolas,"courier new"; color: crimson; background-color: rgba(0, 0, 0, 0.2); padding: 2px; font-size: 105%; } fw_xr819.bin from the PR below, replace your current one and reboot.
