I am trying to compile the Blackfin Camera Driver for the OV9655 on my BF548 ezkit. I am getting the following error:
CC [M] drivers/media/video/blackfin/blackfin_cam.o

Any Thoughts?

none of the PPI code will work on systems with more than one PPI. atm you'll have to make the changes yourself.

I mean, can I use something other then the PPI port/driver to connect to the camera?

the only thing we support is the PPI as it's really the only peripheral that is fast enough

Okay, could you give me a start on making the changes? Is there a patch, or thread somewhere?
Thanks for all the help

for the camera driver, no. just look at the failing file and convert all the PPI MMR macros to use a specific PPI.
