Camera interface

Page under construction... Informations on this page are not guaranteed !!

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 data) to see something ;-). Here are the tested sensor models:
  • OV9653

Driver

• From now we consider that you have a supported camera module plugged on you development board
• CSI interface can be driven through the V4L2 (Video For Linux) standard interface as soon as CSI driver is loaded:

 # modprobe mx27_camera

• Then you have to load your camera driver in order for him to "attach" to the CSI one (for example for the OV9653):

 # modprobe ov96xx

• Now it's up to you to configure your camera with the tools/API the camera driver is offering...
