Hi, i am a newcomer to linux, v4l2 and fb. I want to capture images by the "/dev/video0" and display them by "/dev/fb0".
because of lack of ti example for omapl138 lcdk, i use the saLoopBackFbdev for dm8148 and modify some parameters according to omapl138 lcdk hardware.
Some errors occur. The fb initial failed. The minicom display "MMap Failed". I don’t know the reason.
Can anyone help me please? thanks in advance.
