I want to use a watchdog to see if the TX2 system is down.Can I learn from that what should I do?Is there any reference material for reference?
You could refer to L4T documentation → Watchdog Timer.
I can not find it. Could you tell me agin?
Which file?
I find this link:
https://devtalk.nvidia.com/default/topic/975935/jetson-tx1/how-can-i-change-the-timeout-value-and-kick-watchdog-on-jetson-tx1-/
I know “/arch/arm64/configs/tegra21_defconfig” on jetson TX1.
But what is it corresponding to on TX2?
tegra18_defconfig is for tx2. Please refer to L4T document for introduction to watchdog timer.
hello，WayneWWW:
I find the tegra18_defconfig in the kernel src. But I can’t find the watchdog timer in the L4T document.
There are the following contents in the L4T document:
Watchdog

Tegra Watchdog Watchdog reboot from hang
