I use connectivity line micro (STM32F105RBT6). When I go in project>properties, I set the configuration to STM3210C-EVAL as written in the readme.txt.
In defines tab of gcc option, STM32F10X_CL is defined.

Here's the point : clock frequency is half the good one.

If I change STM32F10x_CL to STM32F10x_MD, the frequency is good. I 've checked the system_stm32f10x.c file to see if I can understand why, but it's way too big to find the good option. Can you please help me configure the micro to the good frequency?

Hi Duck,

The SystemInit() function is the point. What you can do is to place a breakpoint there and follow what happens and what goes in the clock config registers.

If this does not help, can you send us a zipped copy so that we can reproduce the problem in our Labs?

Best Regards,
