Hi, I wrote a program using the i.MX Reference Manual Rev. L4.9.88_2.0.0-ga, 05/2018. Clause 126.96.36.199.2 describes how to capture an image from a camera. but the program is blocked on the command VIDIOC_DQBUF. What am I doing wrong?
This error is V4L2 Capture IOCTLs error, described for example at
you may wish to test camera with FSL-UT-V4L2-capture tests described in the linux reference manual of your BSP document sect.5.5.2 Video4Linux API test.
