MIPI camera,
- on 4/04/25 Mipi stopped (after some update?) eg. ffplay does not work.
- on reboot external LG goes to stand by, grub starts, prints
EFI stub:loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID device path and EFI stub: Measured initrd data into PCR9 then stops and led above F7 starts alternating white and color blinks
- power off and on again, hit F2 (call UEFI), accept changes (none!), exit, and grub now starts regularly
- now Mipi works
- on 19/03/2025, while camera was working both on ffplay and on TEAMS, I hit the TEAMS Picture-in-picture mode icon and Mipi stopped working (black screen). Also ffplay stopped working. Works again after reboot. Try to reproduce and reload driver? Never hit PiP icon!!!
- on 10/03/2025 Mipi stopped working everywhere (also ffplay) and required a driver recompilation. This needs reloading the driver modules. Done by reboot, maybe try
rmmod intel_ipu6 and then insmod intel_ipu6 instead
- latest reinstall 14-02-202516:15: selected repositories noble somerville AND noble somerville-treecko; removed-all install-all oem-somerville-treecko-meta, intel-ipu6-dkms, libcamhal0. In the process it reinstalls 6.11.0-17-generic, its headers, modules ... and it reruns update-grub by itself. Reboot selects 6.11.0-17-generic and both ThinkVision and Mipi do work.
- finally followed https://discourse.ubuntu.com/t/intel-mipi-camera-on-ubuntu-24-04/51797
- beware, must have this repository
sudo add-apt-repository "deb http://dell.archive.canonical.com/ noble somerville"
- determine needed drivers by
ubuntu-drivers list, e.g.
oem-somerville-treecko-meta
intel-ipu6-dkms, (kernel modules provided by intel-ipu6-dkms)
libcamhal0
- remove all of them by @@sudo apt remove xxx@
- install them again
sudo apt install xxx (in particular intel-ipu6-dkms recompiles them for the present kernel, so redo if kernel changes (confirmed, it does not work on 6.8)
- check
v4l2-ctl --list-devices
Intel MIPI Camera (platform:v4l2loopback-000):\\
/dev/video0
ffplay -f video4linux2 /dev/video0 must work and https://webcamtests.com/ also
- TEAMS works from firefox
- use
video shortcut (see .local/bin)
