Demo for STM32F2 doesn't complie

I'm trying to build an STM32F205VCT6-supporting binary. Using a demo for an STM32F4Discovery (slightly modified though), I get the following errors:

Code: Select all

Compiling test.c

I slightly modified Makefile and board.h to fit the change from STM32F4 to STM32F2, yet I get the errors. What can I do to fix that?

Edit mcuconf.h in ordet to obtain frequencies compatible with the F2. The maximum is 120mhz for that one.

Hm, could you tell me which values in mcuconf.h I should change?

[Giovanni]

Try

#define STM32_PLLN_VALUE 240

#define STM32_PLLQ_VALUE 5

It worked, thank you very much.
