I am working on LI-IMX274 with Jetson-TX1.
This device’s probe method executed successfully, but I can’t see video0 in the /dev directory.
I can see IMX274 probe method finished with success.
But I see problems with vi, it says
Here is my dmesg output:
[ 6.761133] vi 54080000.vi: vi_probe: ++

[ 6.771457] vi 54080000.vi: all channel register failed
I am communicating with LI-IMX274 with using CSI-A, and here is my device tree sources:
