Failed to flash Orin Nano Developer Kit

We’re trying to flash the Orin Nano Developer Kit using this command:

sudo ./tools/kernel_flash/ --external-device mmcblk1p1 -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

*reference :

We see this message

Linux_for_Tegra/rootfs/lib/modules/5.10.104-tegra/kernel/drivers/mtd': No such file or directory

Flash Log:
flash_log.txt (249.4 KB)

Host PC: Ubuntu 20.04

As a result, it seems to be failing to flash and is not bootable (normal boot without recovery mode).

Can you please tell me how to flash the Orin Nano Developer Kit?

did you run these commands successfully before flashing?
sudo ./
sudo ./tools/
Does downloading and extracting the BSP package make any difference?

Thank you for your response.

We ran those commands before flashing.
We ran it again and checked the logs.

Ran the first command and we see “Success!”.
We ran the second command and got the following warning and error.

W: GPG error: file:/var/cudnn-local-repo-ubuntu2004-  InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 40F6XXXXXXXXXXXX
E: The repository 'file:/var/cudnn-local-repo-ubuntu2004-  InRelease' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

What could be the cause of these warnings and errors?

error from the second command should not affect flashing your device. Can you check if the folder that was missing previously is back? If it’s still not there, then download and extract the BSP package again.

After downloading and extracting the BSP package again, the folder that was missing previously was back and We were able to flash the Jetson Orin Nano.

Thanks to your support, we were able to successfully set up the Jetson Orin Nano!
Our sincere thanks to you.
