I don't understand how the JTAG commands for blowing the fuse could not be transmitted by the parallel port tool. Is there actually some reason why it can't be used blow the fuse, or is it just that the USB tool has the ability to apply the requisite 6V to the TEST pin and the parallel port tool does not? In which case if we apply 6V to the pin and issue the relevant commands through the parallel port tool, the same effect should be achieved, surely? If not, then can anyone advise me whether the USB FET tool can in fact be used with the linux msp430-gdbproxy and whether it supports all the chips? I have seen conflicting reports about this on the mailing list at various times. So currently I am unsure whether buying this tool would be useful. -- Mario Becroft <[email protected]>
