I've been trying to use the UART port for the past two days, and it's driving me crazy. Setting the baud rate to anything other than 200K stops the program from downloading. If you try it without re-downloading the firmware, you get this error:
If you try to download the program after re-downloading the firmware (which works fine), you get the error:
I've been trying to communicate with the Cortex, and nothing I try works. UART communication between two Cortexes works. If I set the baud rate as 200k on the cortex as well, I get either -1('y'), or random letters.
