have you flash the softdevice that is needed by ble_uart_example? devzone.nordicsemi.com/.../

Have you checked if the project IRAM and IROM matches the softdevice specifications. For example if you are using SD110 devzone.nordicsemi.com/.../

if you have done the above two, can you set a breakpoint in the start of the main function and start the debugger in Keil and see if that breakpoint is hit?

if the break point is hit can you please check if there are any APP_ERROR_CHECK that failed making your system reset in a loop?
