Hi Heiko,
Sorry for the first mail, I send you twice because invalid I set an
invalid Subject.
I'm working on px30 mini evb v11 20190507, in particular on camera side. I
see your patch on dts to support ov5695 camera. Once I have enabled the
right config:
CONFIG_VIDEO_OV5695=y
I'm not able to probe the ov5695 camera correctly. In particular I got
the following error:
[ 2.427936] ov5695 2-0036: Unexpected sensor id(000000), ret(-5)
[ 2.438224] ov5695: probe of 2-0036 failed with error -5
Seem's that the camera is in reset, dumping bus 2 I got no address
from ov5695:
root@px30-evb:~# i2cdetect -y 2
0 1 2 3 4 5 6 7 8 9 a b c d e f

I'm missing something?
Thanks in advance.
