Hi, I wrote a program using the i.MX Reference Manual Rev. L4.9.88_2.0.0-ga, 05/2018. Clause 18.104.22.168.2 describes how to capture an image from a camera. but the program is blocked on the command VIDIOC_DQBUF. What am I doing wrong?
I am using imx_4.14.98_2.0.0_ga.
This error is V4L2 Capture IOCTLs error, described for example at
VIDIOC_DQBUF: Resource temporarily unavailable · Issue #3 · fsphil/fswebcam · GitHub
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.
This example is working with webcamera, but i use i.MX8MMiniEVK with MIPI-CSI CAMERA MODULE(https://www.nxp.com/part/MINISASTOCSI)
