i have jetson nx xavier dev kit , recently the jetson suddenly power off by itself and i dont know the reason. i suspect something but first i will tell what i tried. i thought that the powering off is when the board is max loaded it powers off to prevent overheating,but i tried to do stress tests on cpu and gpu and it worked very good and the temps didnt exceed 45deg
second thing , i think the reason is someway with usb ports as the powering off problems happens either when there is usb connected to the board or when i plug usb
there is no specific thing as it may keep working while i connecting 4 usb devices and sometimes it power off when plugging 1 device , it also doesn`t depend on the device (this can be happened while connecting any usb like mouse, camera, microcontroller) or the port this can be happened in any of the 4 usb ports.
i don`t know if it is a coincidence or not but i want help, please as i use the board in my graduation project :'.
this is vdd log after powering off
