Sorry Simon, I've had a look at the manual and your code. But I haven't 
written any code.

I'll continue to plod though it but without JTAG I can't check any code. 
The people from ST could be well placed to do this bit (?) or maybe one 
of the people who put there hand up for the cortex port in the past.

Simon,  your code outline sounds good. I'll look into this a little more.
