s5k4ec camera is not working

thepthep

Hi , I have a problem in CIF camera.
I can't start camera application,  dmesg is bellow

rk818_ldo8peration not allowed
rk818_ldo4peration not allowed
s5k4ec_back_3(rk_cam_sensor:1228): generic_sensor_ioctl cmd(0x3) is unknown !

I tried sudo but same.
I probed the camera pin, no power supply,
I think rk818 ldo swtich is not working, how can i fix it?

First , u need to confirm the driver of s5k4ec is fine .
Use it under the android , if it is oka ...

Oh..  It works with android.
And I checked same message appear  in android but it works....
I think that message means Camera is not working.
So, I will check linux camera application and driver  one more time.

Thank you for your help
