J120 TX2 CSI2 camera: Invalid eof_ts

Hi experts,

I am interfacing a CSI2 camera module to TX2-J120.
I have configure the camera driver (DTSI) and modes supported parameters as per use case requirements.

configs are as listed here:
Resolution: 640*480, Bayer 12bpp
Pixel clock: 150MHz
Max_data_rate_per_lane: 300Mbps
discontinuous clock : NO
Camera Connected on CSI port-4,lane EF & DTS configured for the same.


Whenever we start V4L2 capture,
For the first frame I get a valid sof_ts. But eof_ts is always 0.
From second frame onwards it always reports PXL_SOF error ! -11.

If, I restart the V4l2 capture application, then again same behaviour reported above repeats. Any suggestions ?


hello ravikiran.hv,

may I know which JetPack release you’re working with,
here’s known issue with TX2’s VI drivers, please refer to Topic 1038067 to fix FE syncpt wait failure.
moreover, you could refer to https://elinux.org/Jetson_TX2/28.1_Camera_BringUp for some debug tips.

Hi JerryChang,

Thanks for the quick reply. I will check these patches.

I am using REL 28.1 on TX2


HI JerryChang,

I tried those patches. But no luck. !

Any other patches or suggestions ?
