programming the BF533 video coder/decoder via I2C

Does anybody have experience in programming the BF533 video coder/decoder via I2C?
My I2C_Init function hangs, and I have no idea what's wrong.

thanks,
Gerrit.

Sounds like there's a good market for consultants knowing anything
about BF video processing.

    This I2C issue has nothing to do with video processing its just basic I2C protocol probably just setting up, controlling and reading low bit rate status info.. Add some debug statements to the I2C host routine and see where the process fails. Writing your own I2C slave in software by bit banging the i/o ports is a great way to learn the I2C protocol as well as using the BlackFin as a I2C host. TI has a I2C led driver thats easy to work with because when your successful leds light up.

Would you like some pointers to I2C resources that I used then I wrote software I2C host and slave?

I'm using the I2C library from CarstenKnop, found on
http://www.blackfin.org/.
Unfortunately the system hangs in the I2C_Init procedure.
So any other pointers to I2C progrmming on the BF533 EZKIT are very
welcome.
