Hi TI Team,
We are using custom board based on am625 EVM. In that We are using wkup_i2c0 for csi camera interface. Here I have also attached device tree changes to support ov5640 camera.
But with this changes, I am not getting /dev/video0 interface. Only /dev/media0 interface is created and also getting error [ 1.300458] ov5640: probe of 1-003c failed with error -22
root@xxx:~# v4l2-ctl --list-devices
TI-CSI2RX (platform:30102000.ticsi2rx):
/dev/media0
Cannot open device /dev/video0, exiting.
Please suggest if We missed anything. I am unable to find wkup_i2c0 example from linux ti academy. Is there any other procedure required to setup/enable camera interface associated with wkup_i2c0 for am625 processor.
