Kernel logs on Brillo

I flashed Brillo build on my dragonboard 410C. Build works fine and I could test some sample audio tests aswell. However I donot get kernel logs with “adb shell cat /proc/kmsg” . “dmesg” messages are there but I would like to have /proc/kmsg messages for my debugging. am trying to enable USB webcam on Brillo but somehow my V4L2 query capabilities (VIDIOC_QUERYCAP) is failing. Device open on /dev/video0 was however succesfull.


Please visit for further instructions. Please make sure you have requested an invite on the main Brillo page (, and have been granted access.

I hope this helps!
