Hai,

     i am doing one project on tms320c5515 controller. i bought evm board. i was started doing some sample codes, i just tried uart code it was worked good for few days . but i suddenly gets problem with my uart . it was not at transmitting any thing.

 this code was actually worked, but now this was not working ........

i was just seeing the output in watch in that terminal , transmitting register

UART_THR is not transmitting any thing......... this is my code........please help out from this...................
