Do i need to map FT232RL chip to UART1? is it hardcoded in firmware, or can it be UART2?
Serial debug mode is hardcoded on UART1 (SC20100) or UART5(SC20260).
Ok, thanks.
you can use that or use RS232…whatever you prefer to connect your serial port to your development PC.
Does your PC have RS232?
hmm… i could just use 1 ftdi usb cable (when needed) and put a bulky DB9 on the board.
or put something smaller like a RJ45 connector and connect the 1st cable with this cable
Amazon.com and the board.
come to think of it, i may need to interface some other modules that are RS232 only 
now i don’t know what to put on the board.
EDIT: there’s also this:
i don’t actually need serial debugging on production board, just on prototype. the above one will do just great.
