Hi,
Is it possible to check rst interrupt generate condition with logs or any commands in Jetson Nano?

can we provide some commands to get the log for sys_rst generation by the module?

Our Custom carrier board suddenly shutdown sometime while running.

Any way to debug or any suggestion to rectify?

hello vbhm,

as you can see via pinmux spreadsheets, UART2_RTS/CTS is by default configure as GPIO pins, GPIO3_PG.02/03.

I made you get confuse with heading, my bad. I am asking about SYS_RESET for shutdown. Board is randomly shutdown. we have no issue with power supply.

after random shutdown they checked command,
sudo cat /sys/kernel/pmc/tegra_reset_reason
and it gives them “TEGRA_POWER_ON_RESET”

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

hello vbhm,

could you please setup a terminal to gather instant kernel logs to understand what’s make system reboot randomly.
for example, $ dmesg --follow
