How to disable OEM firewall on Orin?

Hi NV team,

Please refer to the attached log file.
Orin platform also has the same problem as in this topic：Kernl Panic：CPU:0, Error:rce-fabric, Errmon:2 Error Code : FIREWALL_ERR

I refer to the following link to turn off OEM firewall：

But it doesn’t seem to work, because the problem still exists.

My steps：
1，add below context to tegra234-mb2-bct-scr-p3701-0000-override.dts

       reg@4673 { /* CBB_CENTRAL_CBB_FIREWALL_NVCSI_ENGINE_BLF, READ_CTL */
            exclusion-info = <0>;

        reg@4674 { /* CBB_CENTRAL_CBB_FIREWALL_NVCSI_ENGINE_BLF, WRITE_CTL */
            exclusion-info = <0>;

        reg@4675 { /* CBB_CENTRAL_CBB_FIREWALL_NVCSI_ENGINE_BLF, CTL_SETTING */
            exclusion-info = <0>;

2，reflash system img

hello future.wang,

could you please running with flash script instead of tegraflash.py.
$ sudo ./flash.sh -r jetson-agx-orin-devkit mmcblk0p1

Hi Jerry,

The problem still exists, log is attached
err.log (556.6 KB)

hello future.wang,

may I double confirm which register you’re trying to access?

6

Hi Jerry，

No specific registers are accessed.
The reason for this problem is that the following trace is enabled, and then the camera image is obtained using the v4l2 standard API.

This problem will not occur if tarce is not enabled!

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 2 > /sys/kernel/debug/camrtc/log-level
echo 1 > /sys/kernel/debug/tracing/events/camera_common/enable

7

Specific recurrence path:

  1. Enable the trace mentioned above
  2. Pull the camera video stream
  3. Reboot the system

The problem occurs after the reboot command is executed

hello future.wang,

actually, you don’t need to configure OEM firewall to enable VI tracing logs.
here’re steps to check tracing logs.

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 2 > /sys/kernel/debug/camrtc/log-level
echo > /sys/kernel/debug/tracing/trace
cat /sys/kernel/debug/tracing/trace

Hi Jerry，

Maybe there is a misunderstanding.
It is not necessary to configure the firewall before enabling trace, but turning on trace will trigger the firewall to report an error.

The current problem is: I need to capture trace, but after enabling trace, it triggers the firewall to report an error. How to solve it?

hello future.wang,

that’s incorrect. we never seen OEM firewall by enabling trace.
may I double confirm your Jetpack release version, please examine with… $ cat /etc/nv_tegra_release
