On this page you will find useful informations on how to use the Camera/CMOS Sensor Interface (CSI) of the i.MX chip found on your APF board. Currently only the i.MX27/APF27 are supported.

Hardware

• All the signals of the i.MX27 CSI interface can be found on the J9 connector of the APF27Dev development board.
• You should connect an external camera compatible with the CSI interface (8bits) to see something ;-). Here are the tested models:
  • OV9653 (Omnivision sensor found in the 22T1 module from Microjet; no more available for sale :-()

Driver

• CSI interface can be driven through the V4L2 (Video For Linux) standard interface. To activate it you have to:

 $ make linux26-menuconfig
