I recently designed a board that uses the MSP430FR5969 wolverine.
I got TI to send me a couple of samples for the first few boards.
The problem I'm having is getting the chip to respond in any shape or form.
I knew it would be hard to solder, being a QFN48 package. I used solder paste with a hot air gun. When i designed the board I made sure the pins were long so i could potentially touch them up with an iron after. I'm pretty sure all pins are connected right since i can see them from the side(the pin overhangs a little on the sides as well, it's not just under).
I'm using the MSP-FET430UIF to program it. I successfully managed to upgrade its firmware. I'm now using mspdebug with tilib.
The chip successfully gets programmed, I can even debug and step through the program. However it seems that the GPIO pins I tried so far just don't work, they just act like HIZ pins. The only pins I managed to get working were the PJ pins, the ones that jtag is also connected to.
I did make sure the watchdog was disabled.
Is there anything I'm missing? Perhaps a gpio mode I have to enable first? Did anyone else try the new chips, perhaps their design is broken or something, does this happen?
