Ser/Des Driver problem when executing on custom carrier board

[bsp_dev]

Hi,
I wrote a FPD Link Ser/Des driver that works fine on the devkit.
If I use it on our custom carrier board I’m able to read/write the Ser/Des regs (i2c communication) but when I start streaming using gstreamer I get a kernel panic.
log:
ds960_video_failure.txt (8.4 KB)

I thought it should work the same since we use the same SoM (Orin NX).

Any ideas what can be different?
Thanks

hello bsp_dev,

may I also confirm which Jetpack release version you’re working with.

there’re two issues according to your error logs.
for instance,
(1) it has timed out for waiting for camera frames. please check whether you’ve output the sensor stream correctly.

(2) there’s an NULL pointer dereference failure, which usually caused by your NULL device tree property,
please double check you’ve all property values defined correctly.

Hi @JerryChang ,
Thank you for your reply!
Apparently our ports were different on the custom board and this is why there was no data.
We fixed this.
