EMU0 and EMU1 are routed to the JTAG header but no other pulls or jumpers on 
this board, so just the internal DM355 pullup - they will both be "1".
The OpenOCD script seems to be enabling the other TAPs via the ICE though.. Not 
sure what you mean by ICE Pick Mode having issues booting from reset?

I might have to try that later. This is a custom board without the 20-pin 
header, I can get at RESET on a test point or something if I have to.

At the moment I am looking into triggering a watchdog reset with a reset-assert 
handler.. Be good if I can avoid soldering.

If I can get this stuff working we may order a few :)
