Unable to flash drivers onto dev kit with emmc (not sd card)

[crowe-imetrum]

I have previously been using these drivers with Jetson nano dev kits, which are the ones produced by Nvidia themselves. Now we are looking at using the Xavier NX but Nvidia no longer produces these, it is down to third parties to build and sell their own based on the Xavier NX module. We have acquired one such device but it uses emmc rather than an SD card. This appears to cause an error when flashing, when we select the dev kit option through the quickstart.sh script. So we are currently unable to flash this dev kit with the drivers.
