RTOS/CC2640: CC2640F128, CC2650

Part Number:CC2640

Tool/software:TI-RTOS

Hi,

i'm trying to add UART to the Simple Peripheral Projekt out of the SimpleLink 2.01.00 Version. 

If i add UART_init(); to main.c it compiles but the device stucks immediately after flashing.

I'm using the correct Board.h for my CC2640F128 5x5. 

If i try adding uart to the empty CC2650DK 5XD example, everything works fine.

I'm facing the similar problem which is descripted in this thread: 

CC2650 Trying to add Simple to Uart to Simple Peripheral Example

The solution which is provided there, is not enough for my use case. 

How can i add UART to my project?

regards Maximilian
