Camera can't capture on TX2 NX

[xuxuesheng]

Hi,
We are porting fpd-linkⅢ camera driver on TX2 NX with jetson-xavier-nx-devkit-tx2-nx ( tegra186-p3636-0001-p3509-0000-a01 ), deserializer is ds90ub954 and serializer is ds90ub933, refer to gmsl (max9296/max9295) driver. Now, we have configured the serdes and the deserializer is giving out mipi data, but we’re having trouble with the preview. The trace log shows CHANSEL_SHORT_FRAME.

command for capture:
v4l2-ctl --set-fmt-video=width=1920,height=1080,pixelformat=UYVY --set-ctrl bypass_mode=0 --stream-mmap --stream-count=1 --stream-to=t.yuv -d /dev/video0 --all

Boost the clocks to try.
If didn’t help that tell the sensor output size less than expected.
