Dear all. I found an old Xavier NX core (i think it’s emmc version coz i found this number :900-83668-0000-000) so I bought a board for it. I was using ubuntu 18.04 in vmware and installed sdkmanager_2.1.0-11660_amd64.deb and tried to flash Jetpack 5.1.3 , only chose Jeston Linux since there’s only 16GB emmc.
i did exactly as the tutorial:
add a jumper between FC_REG and GND
connect usb port to my PC
power on the board
here’s some screenshots might be helpful
