Posting this interesting event, in case someone can see why it worked: Banana Pi M4 zero (H618) gained HDMI audio when upgrading to Linux 6.12.30 https://forum.armbian.com/topic/50773-bpi-m4-zero-hdmi-audio/ But in this thread, there's a report that upgrading to 6.16.8 (from 6.15.4) lost HDMI audio

Can you clarify that you made a custom H618 board ?? (not exactly Orange Pi Zero 3?). If I remember correctly, you had previous success with an ili9341 and the same linux board? You need to compare the DTS that worked for you (with ilitek, ili9341, right?) and the new DTS you are trying to modify (with panel-mpi-dbi, for ili9488). Make sure you haven't changed the GPIO in the DTS, and the connections in the LCD and your Linux board. If the ili9341 was working for you with the H616 armbian configuration, changing to H618 might need changes in the LCD DTS from that change.... to make those SPI pins to be addressed correctly. That previous H616 armbian configuration... what Linux board was it meant for? Change back to the configuration that made your board work with the ili9341.

Now that you can replicate the crash anytime. Right after it crashes: $ dmesg $ journalctl -u lighdtm Also, try another application that will use the LCD continuously, without starting X11: $ mplayer -vo fbdev2:/dev/fb0 videofile.mp4 (use a 320x240 approx video, so it will be smooth without hardware acceleration) If it works, then maybe X11 is the problem, not the LCD driver. I wish more people switched to 100% Wayland in their HDMI monitors and LCDs. I have a method.

I am glad you made the LCD work with a DRM driver Three clarifications: the driver panel-mipi-dbi is provided in the OS image you write in the microSD. The DTS is something you get from this thread, and install it with armbian-add-overlay. Kungfupancake provides a txt or a bin file that defines the configuration sent to the LCD, when the kernel driver starts, and instructions on how to install it. The panel-mipi-dbi driver (the recent versions I tried) does not support X11, and you need 100% Wayland, and 0% X11 See my thread to install rpi-greeter (one of the 2 login managers that work with Wayland), and Labwc:

Yes, One/some/all of those kernel configs may be needed for analog audio. Start with the activating configs that correlate with the missing kernel modules * snd_soc_sunxi_machine * snd_soc_sunxi_ahub * snd_soc_sunxi_ahub_dam If it still doesn't work, activate all the 2 other linux kernel configs: internalcodec and aaudio

That's good news You are using lightdm with the default greeter GUI, right? That means that your LCD driver can support X11. Are you still using adafruit,yx240qv29? Maybe the lightdm service is getting confused about which display to use. What do you get with: $ ls /dev/fb* ? Make sure that you don't connect an HDMI LCD at the same time. Which desktop(s) do you use? XFCE and Gnome?

If you have X11 installed, then boot with only the LCD and try: sudo systemctl stop lightdm (the greeter, which requires X11) sudo startx Show me what errors you see If you have Trixie, boot with only the LCD and: sudo apt install labwc labwc (as a regular user) Large language models are just google on steroids. They can only give good answers, if hundreds of people have typed and published solution similar to your problem.

Jeffrey, Is your DTS using this in the "compatible" line: adafruit,yx240qv29 ? Are you trying to use an X11 or Wayland greeter and desktop? (I can't remember what commands to use to check that right now). I didn't know about X11 problems with adafruit,yx240qv29 (only with the other driver panel-mipi-dbi) There's no available image to download with all the required parts.

Yes, that is the correct sequence of actions: 1. Build armbian minimal with panel-mipi-dbi kernel module 2. Use DTS so that the kernel links the GPIO, SPI to the panel-mipi-dbi kernel module 3. Use the bin file (originally provided by Kungfu pancake) <-mandatory, not optional 4. If you see console text successfully in the LCD during boot, you have successfully installed your LCD 5. Tell us here, for the next step in GUI installation The "greeter" is the graphical login screen. Labwc is the wayland-based compositor and window manager (I think).

Rebuilding all the image doesn't represent much more time than the time to recompile the kernel. I can't advise to download the linux source to the armbian SBC, because you would also need the armbian patches. One thing I use for debugging of DTS (and maybe linux kernel modules) taking control of GPIO is: sudo cat /sys/kernel/debug/gpio

Yes. Try the latest kernel. The latest is always the one with the most corrections (unless someone discovers an error). How do you select a H616 vs H618 kernel? I always select Unsupported Board > Orange Pi Zero 3

Urgently go back to the previous selection of dtbos in armbian-config. Just having 1 undesired dtbo may interfere with everything else. Then try adding: overlays=analog-codec in armbianEnv.txt And check the lsmod again

I am lost, confused by your explanation. Are you trying to use the Orange Pi zero 3 and RED LCD ili9488? The solution is: https://forum.armbian.com/topic/47971-driving-the-ili9488-lcd-40-inch-cheap-chinese-clone/#findComment-208446 What did you mean by "booting to 16 bit"?

That photo tells me that you have the SPI and GPIO configuration right. Keep that.
