I’m using Xavier AGX with jetpack 4.9 (R32.4)

I have trouble using D-PHY to get image.

There is signal output from sensor and it looks fine.

Here’s the trace, it keep repeating so I just show part of it:

The trace showed there were PHY error between FS and FE.

I have checked TRM, but still don’t know what do these description “intr_cil_data_lane_sot_2lsb_err1_a”, “intr_dphy_cil_clk_lane_ulpm_req_a”, “intr_cil_lpdt_int1_a” mean.

Any idea?

Looks like intr_dphy_cil_deskew_calib_err_lane*_a and intr_dphy_cil_deskew_calib_err_ctrl_a

Hi ShaneCCC,

Does it mean I need to check GLOBAL class instead of CORRECTABLE_ERR class?

What does the error you mentioned mean?

I didn’t enable any deskew in my device tree

if sensor is not sending de-skew sequence, then there should be error on the link which cause the NVCSI CIL detect a de-skew sync word (0xFF) instead of 0xB8 sync word
