TX2 NX fails to boot after using jetsion-io

Hi,

is using the jetsion-io for applying device tree overlays supported on Jetson TX2 NX? After we apply an overlay, the board gets stuck on Nvidia splash screen and has to be re-flashed.

We are using L4T 32.6.1 and Xavier NX carrier board (P3509-0000).

Thanks!

hello d.zebec,

may I know what’s the bootloader logs, please gather them via serial port for reference,
BTW, please also refer to Topic 188194 to fix a minor bug in Jetson-IO. thanks

Hi,

I tried applying the suggested patch to jetsion-io, it did not change the behavior of the tool on TX2 NX.

I’m able to obtain bootloader logs via UART before applying the overlay, but nothing is displayed in serial console after applying the overlay and rebooting the system.

For reference, I am able to reproduce the issue on a TX2 NX flashed with unmodified L4T 32.6.1 by applying one of the overlays available on the board. I was not able to reproduce the issue on L4T 32.5.1.

hello d.zebec,

FYI,
we’ve reproduce this issue and we’re arrange resources to check this internally.

hello d.zebec,

there’s the u-boot update to include the fix for l4t-r32.6.1.
please download the u-boot binary for TX2 NX. Topic188599_Sep16.7z (222.3 KB)

you should update the attached u-boot binary and execute below commands to update the u-boot.
i.e. $ sudo ./flash.sh -r -k kernel jetson-xavier-nx-devkit-tx2-nx mmcblk0p1
thanks
