Request debug RTCPU image for JetPack 6.0

Hello,

I am currently developing a MIPI camera driver for Orin Nano, and I have encountered an issue where data is not being transferred from CSI to VI. I am using dmesg and trace to check the logs, but it is difficult to identify the issue based on the current logs. Therefore, could you please provide a debug rtcpu image?

Thank you.

Does below command doesn’t get what you want?

sudo su
modprobe rtcpu_debug

echo 1 > /sys/kernel/debug/tracing/tracing_on
echo 30720 > /sys/kernel/debug/tracing/buffer_size_kb
echo 1 > /sys/kernel/debug/tracing/events/tegra_rtcpu/enable
echo 1 > /sys/kernel/debug/tracing/events/freertos/enable
echo 3 > /sys/kernel/debug/camrtc/log-level
echo 1 > /sys/kernel/debug/tracing/events/camera_common/enable
echo > /sys/kernel/debug/tracing/trace
cat /sys/kernel/debug/tracing/trace

Yes, that’s correct.
It is difficult to pinpoint the exact cause based on the current logs alone.
I am attaching the logs as well.
fpga_dmesg.log (1.4 KB)
fpga_trace.log (9.4 KB)

Looks like the NVCSI/VI didn’t receive any validate data from the sensor.
You may need to probe the signal by scope to confirm it.

Thanks

I am a beginner in this area, so could you please explain in more detail about probing the signal?

For your information, I am responsible for the driver, but there are different personnel for hardware and FPGA.

It would be very helpful if you could specify the cases where such a situation is likely to occur.

Thank you.

First confirm the HW connection to configurate the port-index/bus-width.
Then confirm the sensor was output right signal to MIPI bus.

Thank you for your response.

But apart from this, could you please provide me the debug rtcpu image?

Check this binary.
