Jetson Orin can't supply power to mipi camera

[1028803531]

We are using a mipi camera (OCHSA10) under jetson AGX Orin and Xavier, drawing the camera adapter plate according to the pin definition of the Jetson motherboard. Under Xavier, the camera can light up, but under Orin, the camera which is connected to the same mipi channel has no output. The power supply to the camera is normal. Is there any difference between Orin and Xavier in the use of mipi pins?

hello 1028803531,

is it possible to probe the mipi signaling? can you see signals on CSI channel with Orin platforms.

Attached is the complete log, mipi data and clock waveform of orin and xavier from startup to output.

hello 1028803531,

I don’t see other failures besides below RCE error.

[ 1706.518803] [RCE] ERROR: camera-ip/vi5/vi5.c:745 [vi5_handle_eof] "General error queue is out of sync with frame queue. ts=1729472677888 sof_ts=1729498422528 gerror_code=2 gerror_data=401 notify_bits=70020"

this message reported when handling data-corrupting general error, it’ll set the capture channel to error state.

may I know which Jetpack release version you’re using.
if possible, please moving to the latest Jetpack-5.1 release for confirmation.
thanks

Dear JerryChang,

Thanks for your advice. The versions we used were jetpack-5.02 and 4.6, we will move to Jetpack-5.1 to test the camera.

thanks

Dear JerryChang,

After testing, we found that Jetson Orin and Xavier had different requirements on the length of mipi cables, which led to the inability to obtain images: Jetson Xavier could obtain images on the mipi long cable, but could not capture raw data; Jetson Orin can’t get images on long cable, but can get the first frame of raw data. Both Xavier and Orin can get a normal graph and an access to raw data in the use of short line. So is there any way to make Orin as adaptable as Xavier to transfer data over long lines?

thanks

hello 1028803531,

please see-also developer guide for Property-Value Pairs section.
here’s device tree settings, cil_settletime, could you please try tuning this for your camera solution?
