STM32L031 program does not run.

I have developed a small program for the STM32L031 Nucleo-32 using the example UART_TwoBoards_ComIT. The program run on the STM32L031 Nucleo-32 develop-board. When I load* the program to our own HW it does not start, I have tried with and without the compiler directive USE_STM32L0XX_NUCLEO_32. I suspect the system clock generation, but can’t find where it is setup.

*I load the program using STM flash_loader_demo_v2.8.0.



I want to use the ST-LINK V2 for debug should the data port be connected to PA13?


Do any have a hint or comments that could help me?
