This is quite interesting.

For some reason the DSI port is not attached in your setup. For me there is a clear event emitted:

drm-rp1-dsi 1f00130000.dsi: rp1dsi_host_attach: Attach DSI device name=tc358762 channel=0 lanes=1 format=0 flags=0x815 hs_rate=0 lp_rate=0

@nerd,

I added to /boot/firmware/config.txt, under [all]
kernel=kernel8.img
LCD works fine, just like before the changes in config.txt
Touch also works fine.

47

If I run the same setup booting rPi OS, the same setup comes alive. So the connection is OK.

48

@nerd,

I compared it with my files. I have exactly the same entries in the files.

/boot/userconfig.txt is also the same after I manually added dtoverlay=vc4-kms-dsi-7inch.

LCD and touch don’t work for me.

49

Something worth trying:

Edit /boot/config.txt and add after line initramfs volumio.initrd:

# Automatically load overlays for detected DSI displays
display_auto_detect=1

After the change, the beginning of the /boot/config.txt will look like

### DO NOT EDIT THIS FILE ###
### APPLY CUSTOM PARAMETERS TO userconfig.txt ###
initramfs volumio.initrd
display_auto_detect=1
gpu_mem=128
gpu_mem_256=32
gpu_mem_512=32

Kind Regards,

50

Nope, still black, no prompt no GUI.

51

Can you post PCB revision from the command:

awk '/^Revision/ {sub("^1000", "", $3); print $3}' /proc/cpuinfo

Kind Regards,

52 
volumio@rpi5:~$ awk '/^Revision/ {sub("^1000", "", $3); print $3}' /proc/cpuinfo
c04170
53

I checked it too, it didn’t help me.

54

@Piteros

Put the output of the script in this topic.

55

/boot$ awk ‘/^Revision/ {sub(“^1000”, “”, $3); print $3}’ /proc/cpuinfo

Hey @Wheaten,

This is getting really odd. X11 loads DSI... Modeline "800x480"x60.0 just to unload a moment later.
There is an explanation for such magic, we need to find it yet.

Kind Regards,

59

Hey @Piteros,

In your case the X11 is not finding any vc4 drm to even try to enable [ 39.073] (II) no primary bus or device found.

Will take time to figure this out.

Kind Regards,

Yeah looking at your track record, you’ll prob solve it. But it’s weird indeed.
