I didn't think the CFI flash was directly byte/word addressable - which means you can't directly execute code form it.

Certainly the jtag debugger can't download code to it - it won't have the code for the special flash write/erase sequences.

When you load code from flash the reset vector points to an internal memory block that contains instructions to copy your code+data from the flash into 'normal' memory, either internal or external DRAM.
