Hello,
I am writing driver for ov9782 camera Xavier platform
When I start streaming via V4L2 API I get errors from kernel and then kernel crashes

How can I get more details what is wrong about the stream?

Enable the trace to get more information.

I used an advice from this topic
https://devtalk.nvidia.com/default/topic/1052790/jetson-agx-xavier/why-get-video-data-error-through-ov4689-sensor-2-lane-mipi-/2

sudo sh -c ‘echo 1 > /sys/kernel/debug/bpmp/debug/clk/nvcsi/mrq_rate_locked’

helped me to get an image,

But I don’t understand how to fix the pix_clk_hz in the device tree.
I am using ov9782 connected to TI DS90UB954 serdes connected to Xavier

Have a check the sensor programing guide for modify the driver and DT.

Hello ShaneCCC,
I was using this manual

https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-3102/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fcamera_sensor_prog.html%23

there was no serdes_pix_clk_hz field of the device tree like in the new manual above.
I’ll try using it.

I build kernel that I downloaded from Nvidia download site, it is not marked with version but sources are from March 11, on target system I get 4.9.140-tegra

Thanks,
Marina

The document have tell how to download/build the kernel too.
Did you connect to ser/deser? You can increase the pix_clk_hz instead if your case didn’t connect to ser/deser.

I do connect to ser/deser
