I am trying to flash my Beaglebone Black, but I think perhaps there is a
failure in the S2 boot selection button.

This is correct as per the downloads page.

$ sudo dd bs=1M if=BBB-eMMC-flasher-debian-7.5-2014-05-14-2gb.img.xz

Seems to write correctly.
With nothing plugged in to the device
I then insert the Micro-SD Card into the BBB when unpowered.
I hold down S2 and insert the power cable.
The result is always the same, the power light indicator comes on, but
nothing else happens, no other lights come on or flash even if I continue
to hold down S2 or if I release it. I definitely never get the 4 LEDs
coming on for a few seconds which I would expect.
If I insert the Micro-SD Card and insert the power cable without holding
down S2 then lights flash, but I can't really tell what has happened
because if I plug in the display, it is just a load of white dots. If I
boot up with the HDMI cable inserted though, with or without the Micro-SD
Card inserted, ubuntu boots (I previously was able to flash ubuntu onto the
device once).
I also tried holding down S2 when powering on with the HDMI cable inserted,
same result as with no HDMI, nothing happens except the power light comes
on.
Any suggestions would be much appreciated.
Cheers,
Douglas
