libcamera does not work on kernel 5.10.1-v7l+ #4014

I followed the instructions to install libcamera on rpi. (I use rpi 4 model B and my sensor is imx219) The rpi-update command leads to kernel 5.10.1-v7l+ Then, when running the command: cam -c 1 -C I get the error:

ERROR V4L2 v4l2_videodevice.cpp:931 /dev/video13[out]: Unable to set format: Invalid argument

The dmesg says:

[87627.802495] bcm2835_mmal_vchiq: error -1 queuing message
[87627.808096] bcm2835-isp bcm2835-isp: populate_qdata_fmt: Failed vchiq_mmal_port_set_format on port, ret -1

@naushir @davidplowman Are you now both on 5.10? If not then please do update.

naushir commented 3 years ago

Hmmm, I've been running on 5.10 for a week or more, and I don't seem to have any problem. Will do an update and try again.

I do not have any issues with my current kernel build running with imx477 and imx219.

@kamomil, can you conform you are running with the top of tree commit in libcamera?
