Re: MSP-FET430UIF and mspdebug

Hello Daniel,

It is an evaluation board that is powered by a small Lithium polymer
battery with a 3V regulator. I have checked that pin number 4 of the
14-pin JTAG connector is at 3V with the FET cable connected to the
board but I still get the same error. Any ideas where I should look
next please? Thanks.
