I posted this problem last week and additionally do post to resolve.
I commanded "grep "" /sys/class/video4linux/video*/name" and names displayed as a result .
so i think Camera driverr installed.
But preview imags view as a dark. Test time is PM 1:XX. I commanded below line
Result of running camera app is too. and I tried the Friendlycore system to check but it is same.
I hope to resolve this problem please help me.
