Cannot flash TX2 NX with A203v2 Board

Hello,

I try to flash the TX2 NX with the A203v2 with the SDK Manager but it does not work as indicated in the Seeed wiki. Is there a specific flashing software to flash the TX2 NX with the A203v2 ?

Thank you,

Brice

Dear Seeed team,

in addition to Brice_Miramont I went into issue with TX2-NX SOM + A203v2 carrier board.

Followed this tutorial, and started flashing emmc through command line :
Tutorial-of-A20X-Carrier-Boards/#flashing-to-emmc-with-command-line

Applied patchs to L4T R32.6.1 package by replacing :

  • tegra186-mb1-bct-pinmux-p3636-0001-a00.cfg
  • tegra186-p3636-0001-p3509-0000-a01.dtb.

Used this command line : sudo ./flash.sh jetson-xavier-nx-devkit-tx2-nx mmcblk0p1
Is it the right one ?

After first reboot, nvidia boot logo is stuck and nothing happens.
I would like to share the flash.sh log, but as a new user of this forum I can’t…

I reFlashed several times, and managed to have the TX2-NX booting Ubuntu right after flashing process.
But after a power on-off cycle, comes back to nvidia logo stuck.

I saw, this boot unreliability issue with A206 (forums.developer.nvidia.com/t/leetop-a206-carrier-board-boot-issues-boot-unreliability-based-on-temperature/199849/2).
Is there same sort of issue with A203v2 ?

Will share on forums.developer.nvidia.com too.

Thanks,

Is there a way to fix this ?

I am having a very similar problem.

I can flash jetpack 4.6 to emmc via command line without a problem and if I applied the two .cfg and .dtb files that seedstudio supplies as drivers. This makes my carrier boards SD card work. However, I am struggling to get my spi pins to function or get the m.2 slot to recognize an nvme drive. When I modify the pinmux file to enable spi or if I use jetson-io.py to enable spi I get the same boot logo freeze that you are describing on reboot.

Did you ever find a solution?
