HardFault on UART initialize

Benjamin

Hi all!

I'm facing a problem with my UART on a STM32F207IG under CMSIS.

When I try to initialize the UART the processor disappears in the HardFault_Handler.

I think the problem is somehow related to the clock settings which I left untouched until now.

Does anyone have had the same problem in the past?

Every idea is very welcome

The UART section looks like this:

ARM_DRIVER_UART UART1;
ARM_UART_STATUS uart_status;
   
uart_status = UART1.Initialize(NULL, 0);  //<-- HardFault_Error!!
uart_status = UART1.PowerControl(ARM_POWER_FULL);
uart_status = UART1.Configure(9600, 8, ARM_UART_PARITY_NONE, ARM_UART_STOP_BITS_1, ARM_UART_FLOW_CONTROL_NONE);

Thank you in advance

Benjamin
