FYI. This solution just helped another user last week. So should work. The most important point is: you need to provide that xml file.

Trouble Flashing Jetson Nano Dev Boards

Please also try this post. This one is actually same as your problem. The difference is you are using sdcard module while he is using emmc. You should append below line in “p3448-0000.conf.common” and flash: BCFFILE=“bootloader/${target_board}/cfg/board_config_p3448.xml”; Also, make sure board_config_p3448.xml has the correct info of your board.
