Clean CTL STM32 project ends in "HardFault_Handler"

Hi

I am trying to startup a CTL project on my STM32 value line board:

STM32F100RB, embedded ST link.

I am running the newest versions of Cross Studio, STM32 CPU support package V2.8, and STM32F10x std peripheral library update.

I start a new CTL project, and this compiles perfect.

The debugger runs OK, and I can program and run the application.

BUT: I can debug through the startup file, but when I hit the line with "b _start", it enters the "HardFault_Handler", and all the fun stops...

The application never runs, i.e. "Main" is never called.

I have searched anywhere for this problem, but cannot find any solution. I have tried to increase heap, stack and so on, but nothing helps.

I have not written a single line of code myself. It is only Cross Studio generated code.

  I really want to get up and running with this setup. I have used Rowley with NXP ARM7 for years, but have never seen this. I now the Cortex interrupts are very different from ARM7, and it think the problem is caused by some interrupts not handled correctly. 

Please, anyone ???

Thanks!

Kaare

  Did add/replace the stm32_ctl_board.c file from the $(SAMPLESDIR)/STM32/ST_STM32VLDISCOVERY. The default stm32_ctl_board is for one of the other devices.
