Thanks for the reply.

So all I need is a section of assembler in boot.s that copies the 
compiled RAM code from flash to RAM.
I've tried the approach of altering the initialised variables routine 
without success ( my arm assembler knowledge is not so good ).

Once this is copied then how does the RAM code run.  Is it a matter 
of setting PC to a RAM start address?

I'm ensuring that the RAM code is not using any of the ISP RAM area 
by loading it into 0x40000200

Will I need to set MEMMAP to RAM, I'm not using any IRQ's?
