Waiting for target to boot-up... Error while flashing Jetson Orin NX

Hello,

I am currently facing an issue while flashing Jetson Orin NX.

The device currently has Jetpack 6 installed. I need to downgrade it tot Jetpack 5.1.6. The device is Jetson Orin NX 16GB with custom board from forecr (DSBOARD ORNXS Rev 1.11). First off, I installed tegra for linux to my system via SDK Manager. After that, on Orin, I typed

sudo reboot --force forced-recovery

to set my Jetson to recovery mode. Device successfully lists as NVIDIA Corp. on 0955:7323. Then I followed forecr’s guide on flashing jetson

orin_nx_flash_script.txt (2.6 KB)

However, after the flashing process starts, it throws “Waiting for target to boot-up…” error several times. Here is the full log:

flash_3-13.1_0_20260702-135650.log (7.3 KB)

In order to solve this error, i tried bypassing EEPROM check with this command:

sudo SKIP_EEPROM_CHECK=1 BOARDID=3767 BOARDSKU=0000 ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_t234_nvme.xml -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" --showlogs --network usb0 jetson-orin-nano-devkit internal

and results were the same.

Host PC is on Ubuntu 20.04 and its connected to Jetson via Type-C to Type-A cable. I previously tried connecting them via an Ethernet cable on top of USB but that did not help either.

Any insights or guidance from the community would be greatly appreciated.

Thank you for your time and assistance.

Better checking if the board vendor provide you any extra steps to flash their carrier board.

Our default tool and BSP do not support a custom board.

I could not find any extra steps, orin does not boot up after flashing process and scipt stucks.
