Flashing Jetson TX1 Developer board with L4T seems hung


I have connected the Jetson TX1 developer board to an Ubuntu Server using the supplied microUSB cable and put the board into recovery mode.

Running sudo ./flash.sh jetson-tx1-devkit mmcblk0p1 works but it gets as far as this message and does not appear to be going further despite waiting an hour since the message:

Making system.img:
        Populating rootfs from /home/mike/tk1_reflash/Linux_for_Tegra/rootfs ... done.
        populating /boot/extlinux/extlinux.config ... done.
        Sync'ing system.img ... done.

Has it finished flashing or should I wait longer?

I forgot that I had used the | less pipe on the flash command (doh!) so there is more progress when I scroll down.
The system is still happily installing.

Good to know it works, thanks for the update!
