How to enable internal pull-up on I2C2 on Beagleboard xM?

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?
1. Build rowboat-froyo image for Beagleboard xM
2. Measure I2C2 lines (SCL and SDA) from the camera port
3. No toggling, even the kernel issues I2C transaction to probe the camera 
device 

What is the expected output? What do you see instead?

I understand that this is the correct behavior because without a camera 
daughter board, there is no pull-up for I2C2. However the Beagleboard xM manual 
says that I can program the board to provide internal pull-up. Can anyone tell 
me how to do this? Thanks!

What version of the product are you using? On what operating system?

Beagleboard xM, on rowboat-froyo.

Please provide any additional information below.
