Flashing multiple Jetson Orin Nano

Hello devs,
I am trying to multiflash 2 jetson orin nano together using initrd but I am facing problems. This is the procedure that I am following

  1. Boot one orin in recovery mode
  2. Create a Massflash package using the command below

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --no-flash --external-device nvme0n1
-c tools/kernel_flash/flash_l4t_external.xml --network usb0 --massflash 2
jetson-orin-nano-devkit external

  1. Boot the other in recovery mode and flash

sudo ionice -c 1 -n 0 ./tools/kernel_flash/l4t_initrd_flash.sh --flash-only
–network usb0 --massflash 2 --showlogs --keep

  1. Here I get the error Flash complete with failures. I am attaching the log files. To my understanding it is something related to ssh but I can’t figure out if its because of wrong procedure or something wrong with my network settings.

Hi,

Please try to disable the firewall before flashing.
Also make sure the NVMe (SSD) on those two devices.

Thanks

Hello David,
Thank you for your reply. I had already disabled the firewall on my Ubuntu. I have NVMe SSD on both.
I ran the whole procedure again just after confirming the status of firewall but I am getting the same error. Is there any other checks that you want me to run. Also it says to install Secureboot package but I can’t find it for Jetson Linux 36.4.3

Hi,

Before flash two devices, do you make sure those devices in recovery mode?
Please use lsusb to verify.

Thanks

Yes they are in recovery mode

I think I have figured it out. One of the jetsons was a fused board which made it ask for a secure boot package. When I created a mass flash for only 1 and flashed the one that was not fused. It worked. Conversely when I tried to reuse the environment for flashing the fused one it failed.

Also if I manually flash it without any dependencies I can’t install TensorRT on the fused board is there any command I can do to ‘unfuse’ it?

Hi,

Do you execute below commands to install tensorRT

sudo apt update
sudo apt install nvidia-jetpack

Thanks

Yes this worked. Thank you
