 ### flash_jetson_external_storage.sh
 Flashes the Jetson attached to the host via a USB cable. This script must be run on the host machine. The Jetson must be in Force Recovery Mode.

The SSDs must be PCIE, SATA does not work. For the Xavier NX and Orin NX and Orin Nano, this flashes the QSPI memory on the Jetson module.
