I'm using the M52233 DEMO board with Code Warrior version 7.1. I haven't been able to get any output from the UART channel 1. If I use code like this:
uart_init(1, SYSTEM_CLOCK_KHZ, kBaud9600);
I expect an output that I don't actually get. If I use these same function calls with channel 0, I see the character come out on an oscilloscope. Reading around other posts, I see people recommending making sure the GPIO setting for those pins are correct, but going by the schematic for the board the UART TX/RX pins don't seem to be multiplexed with any other IO pins (and I can't find a pin diagram in the 5223x manual). I'm also not clear if I can leave the RTS/CTS pins floating for channel 1. They aren't connected on channel 0 when I get it to work there, but the channel 0 pins are also jumpered to the DB9 connection. I'm not sure what I should look at next.
