It look like hardware error, I will check the layout. thanks.

In that case your approach seems correct. The reason why the chip restarts all the time, is because one of the APP_ERROR_CHECK(err_code); is triggered with an error code. How you can debug and find the error code with Keil is explained in this thread.

Hi! thanks for replay. In this case, I don't need bsp module, so I prefer to remove it, but UART module does't work correctly.

Could you advice how to use UART without bsp module?

Hi,

If you have a custom board, you should instead create your own board file. Don’t remove the bsp module.

You can find the board files under:

\SDK_INSTALL_FOLDER\examples\bsp

When creating a new board file, simply copy the e.g. the pca10028.h file, rename it, and modify it after your requirements (change pin configuration). Then you have to modify boards.h to support your new file, and add a new define that you specify in the Keil options to include your modified file(Options for Target -> C/C++ tab-> Define-> remove BOARD_PCA10028 and add your BOARD_CUSTOM). The bsp module is very dynamic, and will configure according to your board file.
