Hi, I am working on RM57 dev board and trying to make UART -> Serial output working.
I am using TeraTerm to receive ASCII characters but I am getting garbage characters. Terminal settings: Baudrate 9600, no parity, 8 bits data and 2 stop bits.

I initialized SCI 1 - 4 and added PutChars() function to send.
