I'm trying to use the uart on an MSP-FET to connect to a custom-made board. But I stumble on the first hurdle - getting some traffic through the uart.
I'm bridging pins 12 and 14 (TX and RX) and all other pins are disconnected. I was expecting to be able to loop some data, but I don't get anything.
I'm running Ubuntu Linux 20.4 and I get two tty's - ttyACM0 and ttyACM1. But none of them responds when I connect using minicom.
I have tested with an FTDI serial adapter, and that one works fine. (ttyUSB0)
(MSP-FET = MSP MCU Programmer and Debugger by Texas Instruments, used for developing devices based on MSP430 microcontrollers. It utilises a 14 pin connector with jtag, Spy-Bi-Wire and uart interfaces. )
