NUCLEO-F401RE Cannot use second serial uart to connect external module in yotta
Hi, I'm trying to build my own module in yotta for NUCLEO-F401RE board, but I cannot use serial (tx, rx) to my external module. I found out that yotta target st-nucleo-f401re-gcc doesn't provide other uart port except the USBTX, USBRX in pins PA_2, PA_3. However, USBTX, USBRX only serve as debug message. I'm wondering whether there is any solution that I can do to enable other serial ports. /media/uploads/hank51017/target.json
By the way, the target config shows PA_9,PC_7 as test serial, but it doesn't work as well because they are not a pair of same serial.
