Boards obviously differ, and flash is getting easier to use in small 
amts. But I've always found it easier to do development compiling to 
RAM, with a kernel (or tested portions of a kernel) in flash. So, you 
can re-write your flash whenever you have a body of tested code to add 
to what's there.

Whether you're compiling to flash or RAM can be controlled by specifying 
the address of the start of code space; edit it to an addr in the memory 
segment you want to compile to.

Cheers,
Elizabeth
