typically NAND flashes are connected to some controller on a processor and not to JTAG which means you have to program things from the processor itself. i.e. execute code on the processor. Blackfin systems have a defined software flash programmer interface where people write small apps and then the communication is done via gdb. the gdb stub takes care of loading the code via JTAG into the Blackfin proc. YMMV. -mike
