Dear All,

The UART echo example code is working properly in Ti cloud but it is not working in CCS v7 application.

The blinky code is working properly in CCS application.

Please help me in resolving the issue.

Hi Gunit,

Is your uart_echo example program from Tivaware? If it is, it should work, I tried it several times.

Yes the example code is from Tivaware.

It is working on Ti cloud but in CCS.

If this is a TivaWare example then it should work. Did you properly configure the baud rate, number of stop bits, parity bit in your terminal window? They must match the uart_echo example which 115200, 1 stop bit and no parity bit and 8-bit char length.

Yes, I have configured the terminal in same manner.

Hi,

Try different baud rates. It might work.

Did you try other examples like hello.c? What does the scope capture look like?
