Flashing L4T 32.7.1 on ssd mounted on A206 carrier board


I am using a carrier board A206 from Seeed studio on which is mounted a nvme M.2 ssd.

Previously, I flashed my ssd with L4T 32.6.1 which worked perfectly fine.
I am now trying to flash the ssd with L4T 32.7.1. While the flashing appears to have been successful, I’m not getting any oem-config screen afterwards (no hdmi output).

In the A20X carrier board wiki, it is said the following:

Currently, for the A203, A203 V2 and A205 carrier boards, the driver package only supports JetPack version 4.6, or L4T version 32.6.1.

I was thus wondering if the A206 carrier board was also limited to L4T version 32.6.1 or if it could support L4T version 32.7.1 as well ?


I’ve been running a Jetson Xavier NX on the A206 with an nvme ssd using JetPack 4.6.1 (installed via sdkmanager), which uses L4T 32.7.1.
I’ve just upgraded to L4T 32.7.2 via sudo apt upgrade, but it required modifying the spec in /etc/nv_boot_control.conf with

br@nx:~$ diff /etc/nv_boot_control.conf /etc/nv_boot_control.conf.bk 
< TNSPEC 3668-301-0001-F.0-1-2-jetson-xavier-nx-devkit-emmc-mmcblk0p1
< COMPATIBLE_SPEC 3668-301---1--jetson-xavier-nx-devkit-emmc-
> TNSPEC 3668-301-0001-F.0-1-2-jetson-xavier-nx-devkit-qspi-internal
> COMPATIBLE_SPEC 3668-301---1--jetson-xavier-nx-devkit-qspi-

to match that on the emmc partition, otherwise nvidia-l4t-bootloader fails to find the spec.
