I connect the FPD-LINK device DS90UB954 to i.MX8QM-MEK board, add the driver files and fix the dts file,
DS90UB954 driver display success, but not found the device such as /dev/videoN
I think, the following message is error, I do not know the way to solve it, anybody know it?
what is the mxc_isi.1.capture ?

Hi wanben
one can try to debug it using unit tests and i.MX Linux Reference Manual
Chapter 6 Video
mxc_v4l2_test\test - imx-test - i.MX Driver Test Application Software
Best regards
