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

Bookworm is going to remain as an armbian-build option, right?

My main theory is that linux 6.12 doesn't have the v4l2 improvements needed for hw acceleration, that you can only get with linux 6.13.... The link i published explains that.

Did you compile your armbian OS with linux edge 6.15.x, bookworm, xfce? https://forum.armbian.com/topic/32449-repository-for-v4l2request-hardware-video-decoding-rockchip-allwinner/#findComment-216587

Your gpios lines are declaring reset="i6" and dc="h4"... is that correct? At this point, we can see that all pins are correctly defined and connected. Maybe wire length issue? Bad terminal connection? My wires are 15cm long... directly connected with dupont connectors.

Boot while looking at the serial output, what do you see?

Self compiled Armbian Bookworm + XFCE with Linux Edge 6.15.x Then follow all the instructions in https://forum.armbian.com/topic/32449-repository-for-v4l2request-hardware-video-decoding-rockchip-allwinner/#findComment-176981 Then add extraargs=cma=256M to armbianEnv.txt

If it doesn't work, compile your own Armbian with EDGE linux (what worked for me). Stay away from Trixie at this time (its mpv doesn't work as well as Bookworm's)

THANK YOU
