I just upgraded my system to Pi Zero based Diepti system to Bullseye. After recognizing that the camera system has changed (“libcamera”) I nevertheless managed to have the legacy camera system running with RPI Cam.
But unfortunately the camera LED is durably lit in Bullseye: disable_camera_led=1 is not functional. I found this (diepi external) issue, but basically I do not know whether and how I could get this fixed in Dietpi.
Does anyone managed to get the camera LED of a Pi Camera module off in Bullseye?
Issue found in the firmware probe if start_x=1 is not set in config.txt (shouldn’t be necessary for libcamera). It’s been fixed in the latest firmware releases.
I’ve found the firmware bug, which only shows up if using start.elf rather than start_x or start_db firmware files.
Fix created and is up for internal review and eventual release.
Well, as far as I understood it, running Bullseye should handle firmware updates automatically by use of apt. rpi-update is always mentioned to be “unstable”.
Finally, today I re-checked for updates, and yes: there are updates for the raspberrypi-bootloader and the raspberrypi-kernel. After updating the system and reboot: LED is OFF!
