Hi,

I recommend that you take a look at the UART example in the SDK. You can find the source code and the project file of the example in the following folder: <SDK_InstallFolder>\examples\peripheral\uart.

You can download the SDK 12.3 here.

The continuously printing of "start", means that the device is restarting. A reset indicates that you are running into the error handler, where the default behavior is to do a reset. You should then debug in order to find the reason for the reset. See this post about debugging.
