@Harrie_Bosgraaf What’s your Pi model?
You might try adding
dtoverlay=vc4-kms-v3d
to “/boot/userconfig.txt”.
I will try tonight when i come back from work, thanks in advance
@gvolt This did the trick! Whoehoe, a working touch display! You guys are the best! Kudos
regards
Harrie
Seems I having issues running BW V4.015, rPi4
Touch display V3.5.5
Waveshare https://www.amazon.nl/dp/B0BW5Z2L7P
After upgrading BW V4.010 to V4.015 and uninstall and upgrading touch display:
How is your “/boot/userconfig.txt” looking?
# Add your custom config.txt options to this file, which will be preserved during updates
dtoverlay=gpio-ir,gpio_pin=23
Nothing else is added as it just an OTA from V4.010 to V4.015. Which did work in this configuration.
Added to test:
dtoverlay=vc4-kms-v3d
which give me my light back.
@nerd
Any reason for this inconsistent behaviour?
Question guys, when my screen jumps to screensaver the screen is black with the text “no signal” I think that means that the screen thinks there is no hdmi input. Is it possible to get the screen completely black?
Gues you also need to add dtoverlay=vc4-kms-v3d
Thanks, that worked.
Hey @Wheaten,
According to the specs sheet, not only kms need to be active, but also
dtoverlay=vc4-kms-dsi-7inch
I have my doubts, but depending on the DSI port attachment:
dtoverlay=vc4-kms-v3d
#DSI1 Use
dtoverlay=vc4-kms-dsi-7inch
#DSI0 Use
#dtoverlay=vc4-kms-dsi-7inch,dsi0
Kind Regards,
Adding just dtoverlay=vc4-kms-v3d
was sufficient to get the screen working. Interestingly, both SimonE and I have encountered this issue since V4.015, prior to that version, no such overlay was needed. Something has clearly changed in the system’s behavior.
This screen has always been plug-n-play on Bookworm (same on Buster with adding display_auto_detect=1
)
I am facing an issue where YT music doesn’t give output though playbar shows it as playing. Workaround is to go to Play back Options and do a “Save” in the audio device settings. Facing this with below 2 setups. Spotify seems OK.
- Pi 3B with IQ Audio Pro HAT
- Pi 4 with USB DAC (behringer USB audio interface)
Logs here: http://logs.volumio.org/volumio/QRfEx9d.html
Same for me:
PI3B with original Raspberry 7 inch display.
dtoverlay=vc4-kms-v3d
is required in userconfig.txt to get it running.
Thanks.
This is related to what I had reported on the main thread for the plug-in.
After crashing my pi4 and pi5, both unrecoverable and needed reflash, while upgrading the plugin, I reinstalled 4.015 on the Pi4, tried to install the latest stable version and then it also gave this error.
Pi4b 8gb, working fine on 4.014, including Touch Display.
OTA update to 4.015, everything worked except Touch Display…it booted fine and screen is on but just black background. Only overlay applied is arm_boost=1. I can get in from web gui, so I uninstalled 3.5.4 and installed 3.5.5 and neither worked. Something about unable to reach xserver. I’ve rebooted and reinstalled 3.5.4 and problem remains. Here’s a log.
Did you try adding this to userconfig.txt yet? Worked for me
Thank you kind sir. Reading and comprehension had escaped me. I had thought I didn’t need that overlay anymore, as has been the case since the alpha.
