Unable to fuse Orin NX

[hopeful99]

• Running Jetson Linux r36.3
• Orin NX

odmfuse fails with error: Failed to get address for br bct from nv3p helper.

sudo ./odmfuse.sh --test -i 0x23 -k "pkc.pem" -S "sbk.key" -X "fuse.xml" jetson-orin-nano-devkit

Same error with any combination of with/without --test and with/without -k "pkc.pem" -S "sbk.key"

Powering the board off and on again doesn’t solve it. Rebooting the computer neither.

Last few lines of the logs:

Command tegrarcm_v2 --chip 0x23 0 --oem dump bct tmp.bct
Reading board information failed.

Before running odmfuse.sh the command ./bootloader/tegrarcm_v2 --new_session --chip 0x23 --uid succeeds and returns the ECID. After the odmfuse.sh fails, the same command does not return anything. I guess the board ends up in a weird state.

While odmfuse.sh there are no log messages in dmesg

Any idea what is going on and how to fix it?

I solved it! I was out of ideas, so I did a simple re-flash of the board. It succeeded without problem and I booted into Ubuntu. Then i went back into recovery mode and re-tried the odmfuse. Which worked without issues. Below is the command I used to re-flash the device:

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_t234_nvme.xml -p "-c bootloader/generic/cfg/flash_t234_qspi.xml" --showlogs --network usb0 jetson-orin-nano-devkit internal
