Hello everyone,

I am hoping to flash my Orin NX 8G device on Xavier NX devkit or my carrier board. The JetPack version is R35.3.1. I am unsure of which command to use.

Specifically, I am wondering whether I should use the
“sudo ./flash jetson-orin-nano-devkit external” command
or the “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”
command to complete the flash process. Can anyone provide some insights, Thanks.

I am not sure what ‘only supported via l4t_initrd_flash.sh’ means.
Is means I can not use ./flash.sh?

Hi Jerry-W,

Yes, Orin NX does not have internal eMMC, so please use initrd to flash into external device like NVMe drive.

If you are using Orin NX + Xavier NX devkit carrier board, please use the following command to flash the NVMe.

$sudo ADDITIONAL_DTB_OVERLAY_OPT="BootOrderNvme.dtbo" ./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 p3509-a02+p3767-0000 internal

Thank you Kevin, but I have two questions. The first one, P3767-0000 is the Orin NX16GB module. I use the Orin NX 8GB module. Do I use the same command?
The second question, what is the use of “ADDITIONAL_DTB_OVERLAY_OPT=“BootOrderNvme.dtbo” ”in the command? Can it be omitted?

Sorry, I just found it should not be supported in Jetpack 5.1.1(R35.3.1).
Please refer to the following thread for detail.

i met the same question, and my GPU is jetson orign NX 16GB, when use the cmd “sudo ADDITIONAL_DTB_OVERLAY_OPT=“BootOrderNvme.dtbo” ./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 p3509-a02+p3767-0000 internal”, it post the error:“exportfs: /home/sq/nvidia/nx/Linux_for_Tegra/rootfs does not support NFS export”

You can try it out using SDK Manager. I was successful using SDK Manager on the Xavier NX carrier board.

Hi, I am attempting to flash a Orin NX 16GB module with Xavier NX devkit carrier board. I get a FileNotFoundError when invoking BootOrderNvme.dtbo, the rest of my flash command is identical to what @KevinFFF commented. Any fixes?

Please apply the following patch for Orin NX + p3509 carrier board.

Hi, I made the change via the patch you posted but get the same error about BootOrderNvme.dtbo not being found. Are we meant to manually define this overlay somewhere?
