hello knickels,

please check below, here’re several board configure files for Jetson Xavier NX.

$ ls jetson-xavier-nx-devkit*
jetson-xavier-nx-devkit.conf  
jetson-xavier-nx-devkit-emmc.conf  
jetson-xavier-nx-devkit-qspi.conf

may I know which Jetson Xavier NX board you’re working with?
please use jetson-xavier-nx-devkit.conf , if you’re having a SD-card version board.
for example,
$ sudo ./flash.sh jetson-xavier-nx-devkit mmcblk0p1
thanks

It’s got an SD card on it, so I tried this command line with pretty much the same result as the first time: “CPU Bootloader is not running on device”

hello knickels,

could you please check Write Image to the microSD Card to prepare your microSD card,
follow that proceed to set up your developer kit.
thanks

Yes - this was one of the first things I tried (Feb 11).
The board won’t boot the new image - serial log above.

hello knickels,

I suspect Jetson product is defective,
please contact the NVIDIA Customer Care team for the RMA process.
thanks

OK, I’ve made contact with them.
I can’t find any number that obviously says it’s the serial number - where is it printed on the board?

hello knickels,

it’s EEPROM to store those board information, please check Jetson Module EEPROM Layout for reference.
for example,
I’m able to dump board info, 3668-0000-200 G.0

$ i2cdump -f -y 0 0x50
No size specified (using byte-data access)
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f    0123456789abcdef

please have a try to add board info to flash commands if you’re able to dump those board info,
for example,
$ sudo BOARDID=<> FAB=<> BOARDSKU=<> BOARDREV=<> ./flash.sh jetson-xavier-nx-devkit mmcblk0p1
