Programming Pins for the MSP432

Philip McCorkle

Simple question - What are the pins that I need for programming the MSP432P401R using an existing MSP432 Launchpad? I'm trying to make a prototype PCB of my own and I'd like to use the Launchpad as the programming, just as I have done with the MSP430 Launchpad. From what I understand, it need SWDIOTMS (pin 94) and SWCLKTCK (pin 95), as well as a common ground (duh...). Is this correct or do I need other pins?

    Hi Philip!

    For 2-wire SWD debugging/programming you need SWDIOTMS (pin 94) and SWCLKTCK (pin 95), in combination with the common GND, right. Make sure your target board has the same supply voltage, or add some level translator or protection resistor in series with the data lines (or power the target from the LaunchPad as well). Your IDE needs to be set to SWD debugging without SWO and of course the MSP432 on the LaunchPad has to be disconnected from the data lines.
