1. Put the target device into Force Recovery Mode.

  A. Power on the carrier board and hold down the RECOVERY button. 
  B. Press the RESET button. 

2. Using Standard flash

sudo ./flash.sh jetson-orin-nano-devkit-nvme internal

3. Jetson Orin Nano Developer Kit (NVMe):

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 \
  -c tools/kernel_flash/flash_l4t_external.xml -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" \
  --showlogs --network usb0 jetson-orin-nano-devkit internal

4. Jetson Orin Nano Developer Kit (USB):

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device sda1 \
  -c tools/kernel_flash/flash_l4t_external.xml -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" \
  --showlogs --network usb0 jetson-orin-nano-devkit internal

5. Jetson Orin Nano Developer Kit (SD card):

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device mmcblk1p1 \
  -c tools/kernel_flash/flash_l4t_external.xml -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" \
