Status update: OCD and JTAG enabled but no jtag cable connected,
lots more code into the M64. Led flashing happily, messages
being sent out correctly on RS485 com (usart1), relay clicking normally...
it is starting to look and feel just like a bought one :-)

I'll leave it running on it's own overnight. This morning it was flashing
erratically, perhaps I had some junky test code. I'm now starting to put
in it real code and it seems ok. No doubt there will be lots of questions
as I venture out of the comfortable 8K memory boundaries, some of the
registers in the large chips seem to be a bit of a dog's breakfast....
not that there is anything wrong with that!
