You've selected UCSSEL=2, which I believe is SMCLK. Then, you're dividing it by 12. So you need to make sure that's what you want. To get more help, look up the USCI-I2C mode chapter in your board's user's guide. For example, if you're using G2553, look up the chapter in the file titled: "x2xx User's Guide".

Hi, I would like to note that if the jumpers are not set right on some boards, the UART pins will be disconnected and won't work. Therefore, a board with bad jumpers setup may appear that UART isn't working. (Board's User's Guide shows the jumpers setup).

Did you solve this problem?
