I used mass flash tool to flash 8 Xavier-NX at the same time,and I got 3 issues.
Platfrom:Xavier-NX with emmc
PC: Ubuntu 18.04
usb hub 3.0*2
I ran nvmassflashgen.sh,and I got the tar file.
Then, I entered 8 Xavier-NX to the RCM mode,and ran the nvmflash.sh.
But it shows less than 8 PID,I try 10 times just one got 8 PID.
After flash,the chromium icon is broken in some Xavier-NX.
Some Xavier-NX otg are fail.
