Hi
We would like to use the Signals UART3_TX and UART3_RX as a serial interface. We were able to disable the debug console on this interface in the device tree so that there is no more output from the kernel. The problem is that we still get debug messages before the kernel is loaded. Can anyone show us the necessary steps to disable any output on this interface for the Jetson AGX Xavier? We are using JetPack 4.2.2 and JetPack 4.3.
Thank you.
If we change the flags as you suggested, the system still has output on uart3 and it also gets stuck in the boot process. Here the log: boot.log (6.0 KB)
There is nowhere inside the JetPack Folder a File with the name tegra194-mb1-bct-misc-galen-int-p2888-0000-p2822-1000.cfg . We tried adding it to the File bootloader/t186ref/BCT/tegra194-mb1-bct-misc-l4t.cfg, but then we get an error “Invalid token debug.enable_log”. Also when we search inside the JetPack Folder, the token “debug.enable_log” can not be found anywhere.
We will try to do the modification in cboot and check if it works. But if there is an easier way to reach our goal, let us know. We would prefer not to build a customized bootloader.
Thanks
