Hello,

I'm using a sabre board i.mx6 with Android 13.4.1 pre-charged from Freescale.

Hi Macro Cubisino,

Even I am facing the same issue, got any solution for this. If so please let me know, that would be helpful.

Thanks and Regards,

Edited :

One thing that you can check is that, is your camera's working properly. Also please see the kernel boot log. In my case the log shows

--------------------------------------------

camera ov5642 is not found

USB Gadget resume begins

fsl_udc_resume, Wait for wakeup thread finishes

ov5640_read_reg:write reg error:reg=300a

camera ov5640 is not found

ov5640_read_reg:write reg error:reg=300a

camera ov5640_mipi is not found

--------------------------------------------

so i am doubting the camera's. I think there may be some problem with camera. Please check your log.
