CAMERA_PF_GRAYSCALE mode not working

[ankitdaf]

Hi

I tried replacing the CAMERA_PF_RGB565 with CAMERA_PF_GRAYSCALE to start getting grayscale images from the OV7670 but keep on running into LoadStoreError.

I uncommented the necessary lines and the LoadStoreError triggers here :
branch : framebuffer_overlay
file : camera.c
line 911 : dst[0] = src[0].sample1;

From here : https://github.com/SuperHouse/esp-open-rtos/wiki/Crash-Dumps
I find that it is likely because of trying to access a byte or word in a manner not allowed.

@tekker @igrr Did you manage to get grayscale mode to work with this branch ?
Any pointers are appreciated!
