Hey Bryan,

I don't see the second print (..."virtual channels mask 0x0") on my side when testing with the standard imx577 driver. I also have imx577 on slot 2 and ov9282 on slot 1. I am testing with:

media-ctl --reset
media-ctl -v -d /dev/media0 -V '"imx577 '22-001a'":0[fmt:SRGGB10/4056x3040 field:none]'
media-ctl -V '"msm_csiphy2":0[fmt:SRGGB10/4056x3040]'
media-ctl -V '"msm_csid0":0[fmt:SRGGB10/4056x3040]'
media-ctl -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/4056x3040]'
media-ctl -l '"msm_csiphy2":1->"msm_csid0":0[1]'
media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'

yavta -B capture-mplane -c -I -n 5 -f SRGGB10P -s 4056x3040 -F /dev/video0


What is your testing procedure?


Regards,

So for that I just do

https://libcamera.org/getting-started.html

apt install -y g++ meson libyaml-dev python3-yaml python3-ply python3-jinja2 libssl-dev libdw-dev libunwind-dev libudev-dev libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libevent-dev

git clone https://git.libcamera.org/libcamera/libcamera.git
cd libcamera
meson build
ninja -C build

cd build/src/cam

./cam -l

Available cameras:
1: 'ov9282' (/base/soc@0/cci@ac4f000/i2c-bus@1/camera@60)
2: 'imx577' (/base/soc@0/cci@ac50000/i2c-bus@0/camera@1a)

./cam -c 2 --capture=10 --file

Do you have the ov9282 probed ?
