Have you tried your python script with your Linux PC? If it happens again, you can tell that the problem is within the ESP32 program. I generally prefer having the most complex system (Armbian) poll the simplest device (ESP32), instead of the ESP32 interrupting the Armbian system. I found it more stable that way. Stay with wifi, and use the ESP32 serial port just for debugging. Program the ESP32 print an acknowledgement of data requests, and an alarm if it gets stuck in an unexpected state. I have also found ESP32 circuit or micro python very stable for serial port communications.

I don't see it as the very latest bleeding edge kernel version. I see it as a newish Linux, which already has the armbian patches updated for. Some CPUs end up with newer or older Linux versions, due to varying levels of development success. For example, sunxi's armbian edge is 6.15.4 today, but the linux trunk is up to 6.17-rc6 ... (not available in Armbian)

Building a rolling release is more than just showing that in the MOTD. If you do "sudo apt upgrade" in an OS image you just built, you probably will have zero or one packages to upgrade. If you start with an image built a long time ago, or with packages defined a long time ago, then "sudo apt upgrade" would take a long time.

I have the same debian as you: 5.1.4-xxx-v4l2request, installed over Debian Bookworm, with Linux 6.15 (OS built by myself). When I tried the ffmpeg-7.x.x-v4l2request for Trixie, I could not get hardware acceleration.

Search my threads with keyword "ili9341". Post a photo of your wiring, a schematic, and what did you try within armbian... in this thread.

That will definitely make you not get hardware accelerated video Make sure to follow the 3 commands to install the custom repo, its certificate and higher priority: sudo wget http://apt.undo.it:7242/apt.undo.it.asc -O /etc/apt/trusted.gpg.d/apt.undo.it.asc . /etc/os-release && echo "deb http://apt.undo.it:7242 $VERSION_CODENAME main" | sudo tee /etc/apt/sources.list.d/apt.undo.it.list $ echo -e "Package: *\nPin: release o=apt.undo.it\nPin-Priority: 600" | sudo tee /etc/apt/preferences.d/apt-undo-it sudo apt update Then check that the new custom dpkgs are available for install/upgrade apt list ffmpeg-whatever Here's how I force install a specific version: sudo apt install packagename=nn.nn.n

Share your displaying configuration by running "neofetch" and post it here. If your X11 is running on top of framebuffer, instead of DRM, it wont work. I also would like to get more debug from cedrus, linux's v4l2... but at least you can add -v to mpv to get more debug You only need the ffmpeg plugins offered by the original poster of the v4l2-request thread This is tested with mpv player only. v4l2-util and -ctl are only useful for webcams and video capture devices. v4l2loopback is not involved here. I don't have it I have an orange pi zero LTS, but I havent tested it there (I would use an SPI LCD, since it doesn't have an HDMI prot)

For debian problems, do what I do: Get the cheapest raspberry Recreate the problem Ask the question in the raspberry forum Apply solution to Armbian XD

XD take your concerns to Canonical

With the armbian build system, you can build either Bookworm or Trixie You will always get the latest Bookworm or the latest Trixie packages in a freshly built armbian OS. This is what's meant by "always rolling release"... not to be understood as "always sid or Trixie". Independently, the armbian build system will let you choose a stable Linux version, or the latest available from Armbian (edge).

You are still using an old Linux. You need Linux 6.13 or newer. You need to build your own Armbian OS. Also, don't forget the cma=256M kernel argument

Get the microsd card mounted in your linux laptop Open /boot/armbianEnv.txt Add the line: extraargs=plymouth.enable=0 disablehooks=plymouth https://wiki.archlinux.org/title/Plymouth When you get booted in your armbian OS: sudo apt remove plymouth

I don't know anything about this patch, but check this: * Linux version you are using, vs Linux version corneliius has used * Try deleting the hunk in the patch that caused the problem you saw, and see if other hunks cause patch failures * If it is only one hunk causing the problem, look at the file that is affected by the patch drivers/auxdisplay/Makefile: do the lines mentioned in the hunk exist in the Makefile? In the expected line number?

Find a DTS that uses compatible="waveshare,rpi-lcd-35" and try again (I don't use that LCD, so I am not sure... but I know it is special because it contains a SPI-to-parallel chip)

Can you try if any of the H3 images from libre-elec would get you video acceleration? https://libreelec.tv/downloads/allwinner/ i once tried the orange pi pc image in my orange pi zero lts (h3) and it worked
