I had not made any changes to my code since it was working fine yesterday evening. First attempt to flash the part started reporting Read Errors and from there I couldn't reconnect.
Symptoms as follows: - Debugger disconnected - RST line is low for ~50us then goes high and low again after a few us. This could be a very short WDOG timeout? - With debugger connected, RST line cycles with quite slow rise and fall times over around a 100us period between 1.0V and 1.5V. - oocd reports garbage number of breakpoints and lots of read/write errors. I realise this isn't very useful information for debugging the problem but thought I'd record it anyway! I need to get on with development so have taken a trip to Windows 8 to use MSD to reflash the part and can now connect fine.
