Hi developers~:
Currently i am trying to connect a web cam to my board by following https://docs.blackfin.uclinux.org/doku.php?id=linux-kernel:drivers:usb_video_device_class.
After a property configuration i have got those problem:
SDL information:
Video driver: fbcon
Hardware surfaces are available (382k video memory)
Device information:
Device path: /dev/video1
Stream settings:
Frame format: MJPG
Frame size: 640x480
Frame rate: 30 fps
Unable to map buffer: Invalid argument
Init v4L2 failed !! exit fatal
Then i was doing some research, found a commit name 9703 at blackfin.uclinux.org/git/?p=linux-kernel;a=commit;h=8aaa07f7d4f551852179dd667a41de8f9898c043 but additional problem is the linux kernel for blackfin processor might be very customize so some codes are different compare to the documents on that website and some documents are in different location. So i am guessing there should be have another path to slove this case. Cause some other developers have their WebCam working on that board quite well.
