hi：
Now we have a requirement to notify the mcu when restarting and shutting down. I want to know which interface the kernel code calls after executing sudo reboot and sudo shutdown? Thank you!
Hi mingming,
How do you connect the MCU with Jetson Thor?
If there’s the GPIO connected between them, you can simply write a custom service to notify MCU.
hi：
是这样的，能在内核层找到关机和重启的函数吗，我在那个函数里面加gpio的控制
For the shutdown, it will call .shutdown function in each kernel driver.
I will suggest you writing a custom driver for this use case or just create a service to control GPIO to notify your MCU.
