SW2 to put dragonboard in fastboot mode

[rbmistry]

Documentation for Version 1.1 mentions using SW2 to enter fastboot.
This didnt work for me and I had to unplug the camera mezzanine to get access to volume down button S4 on Dragonboard to enter fastboot.
Does this work?

The net of S4 on the Dragonboard is connected to the net of SW2 on the camera mezzanine. Ensure there is a good connection between the mezzanine and the Dragonboard. Then holding SW2 when power is connected to the Dragonboard should cause the board to enter fastboot.

I thought this also until I still had problems without the mezzanine after upgrading fastboot etc... Human error was the root cause as I was expecting lights on the board for a successful fastboot but this is not the case, green flashing is not fastboot.

We added a binary to test the buttons in the 410c_camera_support project.
If you are running version 1.1.1 of the root filesystem then run the following command and follow the instructions.

$ /usr/share/d3/key_test

Otherwise this repository can be downloaded from github and the test is located in "bin/key_test"
