Stuck in flashing process with a custom carrier board for Jetson Orin NX

[lab2022]

Hello,

I am trying to re-flash an Orin NX 16GB on the Seedstudio (J401) custom carrier board.

The flashing process gets stuck at Step 3 with the l4t_initrd_flash.sh command, despite following the instruction provided by the manufacturer on this page. The Jetson Orin NX can boot at the beginning of Step 3, but it gets stuck just after on the error :

 "Waiting for device to expose ssh ...RTNETLINK answers: Operation not supported".

Here is the command I used for flashing :

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 p3509-a02+p3767-0000 internal

Here is the output log :

log.txt (245.7 KB)

I have already tried the following solutions in vain :

• Adding a specification in bootloader/t186ref/BCT/tegra234-mb2-bct-scr-p3767-0000.dts as specified here.
• Changing the EEPROM reading value to 0 as specified here.
• Disabling the USB autosuspend

I do not have access to the UART debugging at the moment.
I am using a PC with Ubuntu 20.04 and want to use the Jetpack 5.1.2.

Could you help me please ?
Many thanks in advance for your help.

Probably your host does not support RNDIS?

Hi,

Thank you for your answer. The problem was indeed coming from the host.
My Linux kernel configuration did not allow IP assignment to USB0, and/or some headers were missing.
Updating my Linux kernel solved the problem. I can flash the custom board now.

Thank you very much for your help!
