I’m use Agx Orin 32GB（35.6.0）, now Dphy is 2.5Gbps and don’t use any serializer/deserializer, how to deskew dphy? I’m only can grab image at <1.5Gbps. Is it necessary to send deskew signal by sensor? I’m looking forward to hearing from you soon.
thanks
Checking with sensor vendor if able to do it.
could you provide me a 5.1.4 rce debug firmware,thanks
Checking with below link.
[RCE] JetPack-5.1.4/l4t-r35.6.0 camera firmware with debug flag enabled.

The msg show likes don’t have deskew, Is there a problem somewhere？ I have already configured the sensor to send deskew signal everyframe, When I set MIPI 750M, I Get [RCE] ISR PHY 0 CIL_B 0x40 msg
The deskew word need send before sensor streaming on and don’t need send every frame.
It’s mean 1:deskew word for sensor 2:v4l2-ctl start_stream 3:sensor config start_stream?
I don’t think so.
Maybe send the deskew word in the xxx_start_streaming() in the sensor driver.
My hardware use dsp to config i2c reg, i can’t send deskew word in start_streaming driver。Is there a problem with this？
No matter what the deskew word need send before the sensor start streaming.
Which file can I find the deskew code? deskew.c looks like not all. Can I disable deskew?
Can’t disable it. And it’s private source to modify.
hello user2341,
FYI,
deskew calibration is a must if data-rate > 1.5 Gbps, Else the camera firmware will continue to wait for deskew signal from the sensor side. it’ll enable pixel parser when deskew calibration has completed.
please also note that, we are only looking for initial deskew calibration; however, it should also be ok to configure the deserializer to send periodic skew calibration bursts. the effect would be that the initial skew calibration can be retried every time the skew calibration burst is sent.
CIL_A 0x88 tell the data lane control error (err_intr_cil_data_lane_ctrl_err0_a). Could be the sensor lane configuration problem.
Could I increase the initial deskew width UI?
I don’t think so.
I have set sensor speed to 1.2Gbps with deskew signal.
I can successfully capture images，but dmesg logs show
[RCE] ISR PHY 0 CIL_A 0xe000000
[RCE] ISR PHY 0 CIL_B 0x6000000
I don’t know what the problem is. It’s sensor deskew signal error?
Is it a software issue or a board hardware issue？
At 2.5Gbps, dmesg only show
[RCE] Deskew setup message sent for port 0 num_lane 4
then display
