As described in the QUICK START GUIDE of Jetson TX2. “Connecting a device while powered on may damage the Developer Kit or peripheral device. The board should be powered down and the power removed before plugging or unplugging devices or add-on modules into the headers. This includes the camera and display headers, the M.2 connector, the PCIe x4 connector, SATA, and the expansion headers.”
I am not sure that can we plug and unplug the USB flash drive while the Jetson TX2 is powered on? thanks!
Electrically USB is “hot plug”, so you can plug it in or unplug it at any time without hardware failure. Even so, if the USB flash drive is in use when you disconnect it, then you may get software errors related to the file system. A flash drive should be unmounted (see “man umount”) prior to removing it (if you don’t care about losing data, then you can probably yank the USB drive at any time).
