Flashing image to TX2 failed

Hi, I tried to a custom made carrier board to flash the TX2, and it will stack at 64% when I’m trying to flash the TX2’s image which cloned from other places, and return code value 3, any ideas about what the return value’s meaning? and how to fix it? thanks.

I found that it is because the host USB is USB3.1. When I change the host USB port to an USB 3.0 port this situation will not happen again
