I’ve been using Khadas Camera for a month already with no issues, and since yesterday I’m no longer able to use it. When I try to run the example in the docs
v4l2_test -c 1 -p 0 -F 0 -f 0 -D 0 -R 1 -r 2 -d 2 -N 1000 -n 800 -w 0 -e 1 -I 1 -b /dev/fb0 -v /dev/video0
I get the following
ds1_out_fmt = 0, ds2_out_fmt = 0, ds1_res = 2, ds2_res = 2
The /dev/fb0 device was opened successfully.

I tried to use a brand new Ubuntu Image, and I have the same issue. Doesn’t work with guvcview software either
Thanks!
