Jetson Nano - brief logo then black screen, no usb connectivity

[jeremyfennema]

When I try to run this command from the blog tutorial:

sudo ./flash.sh -x 0x21 jetson-nano-devkit mmcblk0p1

I get an error which says

Error: Invalid target board - jetson-nano-devkit

The good news is that it definitely shows up with lsusb though, so that’s a step in the right direction. Suggestions? I couldn’t see an obvious reference to the board name I should be using if it was different than what was referenced in the blog. Thanks in advance

I think I found it. In the shell script I see this set of lines:

if [ ! -r ${ext_target_board}.conf ]; then
echo “Error: Invalid target board - ${ext_target_board}.”;
usage allunknown 1;
fi

So it looks like it’s comparing against the .conf files in the main directory. The only 4Gb nano board listing there is:

jetson-agx-orin-devkit-as-nano4gb.conf, so I tried that and now I get a new error:

Error: The Actual SoC ID(0x00) mismatches intended jetson-agx-orin-devkit-as-nano4gb SoC ID(0x23).

and I’m not seeing how to resolve that error now.

I also tried:

sudo ./flash.sh -x 0x21 jetson-orin-nano-devkit mmcblk0p1

###############################################################################
Error: The Actual SoC ID(0x00) mismatches intended jetson-orin-nano-devkit SoC ID(0x23).

But it gave a similar error. Those were the only two conf files which seemed relevant. On the offchance, I also tried setting it to 0x23 instead of 0x21, but it gives the same error.

You downloaded rel-35, which does not support Jetson Nano.
You have to use rel-32 instead, with the latest version being 32.7.4:

Jetson Linux R32.7.4

I just wanted to follow up and say thank you so much @DaveYYY This worked perfectly! I was able to get the board booted up and moving through the configuration steps last night, new user setup, all the normal stuff. Thank you again for all your help and the details you shared. Greatly appreciated from myself and the whole team here at our makerspace!
