I used Ubuntu 20.04 SDK Manager_1.9.3, JetPack 5.1.2, Jetson AGX Orin 32GB.
Every time when I flashed eMMC of Jetson my flashing process stuck in 99%… I used some usb-hub. I also tried many variants, but always got the same mistake. I spent ~10 hours for solving this problem and I solved them.
I escape usb-hub and used short (~15cm) usb-c cable directly from laptop to Jetson - after this my flashing completed with success on the first attempt!
I hope this solving will save time of Engineers who use Jetson and SDK Manager!!!
