JTAG is used to use a PC to program an embedded device. I have made one the parallel port of a PC to recover my Linksys WRT54G. It also, I think, can be used to debug the device.
Its a "standard" which is adopted by manufactured, althought I have not heard of the newer one you mentioned. But I have not been in this field for some time!
So is JTAG "standard" in that if I need a JTAG programming lead then any will do? When I look around a lot of them seem to refer to ARM or whatever, suggesting that the cable is specific to a certain chipset. I ordered a cheap USB JTAG cable off eBay to play with but I'm not sure whether I need to be a bit more careful about picking the right kit for the right job.
