CCS/TMS320F28377S: Serial communication in TMS320F28377S processor-baud rate setting probleum

Part Number: TMS320F28377S
Other Parts Discussed in Thread: MAX3232,

Tool/software: Code Composer Studio

I am using TMS320F28377S microcontroller. and I trying to use serial communication. I use the example code provided in control suit  "sci_echoback". Microcontroller generate output on tx but I thing baud rate is not matching (i test this on putty) . I use this code.This give garbage value on putty. (Putty setting are correct I check then by shorting tx , rx pin of RS232, and max3232  is used for ttl to rs232 converter). Baud rate I set is 2400, Date Bits = 8,Parity = None, Stop Bits = 1, Hardware Control = None.I use c2000 launchpad XL, crystal freq=10Mhz,Clock is 200Mhz.
