TX2-NX Boot from USB

Hi, everyone, I was told that TX2-NX cannot boot from USB in this link:

However, in the R32.6.1 Developer guide, it said that TX2 series can support external storage boot, including USB.

So, can TX2-NX boot from USB?
If yes, is there anything we have to do to make TX2-NX boot from USB?

Thanks

It is still a mistake that you think “flash to usb” directly means you can boot from usb.

Please refer to point 2 in above thread. In TX2-NX, you can only mount the file system from your usb drive since uboot cannot detect the usb device.
