We have our customized BSP based on Nvidia stock BSP.

He is using Ubuntu 18.04 LTS as the host computer.

this is the command used to flash:
sudo ./flash.sh jetson-xavier-nx-devkit-emmc mmcblk0p1

Below is the error:

Are you sure the whole BSP package is clean? It looks like flash.sh returns some error which should not happen if this is a fresh package.

Hi, Here I am sharing more details, Now my customer is able to Flash the nano BSP attached the flash log Floyd-Nano-flash (23.9 KB) , but he says during boot process some messages arrive on monitor for a moment(attached screenshot)

(about 1 sec)
Immediately after this, the monitor turns balck/blank and never boots. Please let me know if you find anything wrong in process or help me in making progress with this.

Another thing I am able to successfully flash and boot with My module with same BSP and carrier board setup what I have, I am not able to recreate the issue.

Then please tell your customer to find another host and use it to flash.

If even you cannot reproduce the issue for your customer, then maybe they didn’t prepare the BSP package well on their host.

Hey, we have provided BSP packages, they just need to flash it and see it is booting to desktop

Yes, I mean maybe they didn’t install it well on their host.
Or you can ask him to switch other NX module to see if it is hardware defects.

BTW, why not ask your customer to directly join the discussion here?
