Running Demo code on STM32F0 discovery

[JohnL]

Hey,
I'm new to both chibios and ARM programming, Im wondering about all the steps necessary to run and load the stm32f1 demo code on a stm32f0 board. Right now I have ubuntu with the gcc cross compiler and st-util. I have just compiled the F1 board and targeted it to the f0 discovery which started loading but didn't finish(understandable), and I think I need some guidance as to which files I need to change.

Thanks

John

To flash I use the following line

Code: Select all

st-flash write  build/ch.bin  0x8000000

I work with stm32l1, but I thinkthe flashing directive is the same for stm32f0 as well.

I find that I cannot work with openocd reliably, but st-flash works.

I think? I just need to point the make file to the f0 appropriate places:include $(CHIBIOS)/boards/ST_STM32VL_DISCOVERY/board.mk

Code: Select all

include $(CHIBIOS)/os/hal/platforms/STM32F1xx/platform.mk
include $(CHIBIOS)/os/hal/hal.mk
include $(CHIBIOS)/os/ports/GCC/ARMCMx/STM32F1xx/port.mk

I changed these, but my make is still tossing errors,
I removed the include stm32f10x.h from stm32.h, now Im getting more fundamental issues:

Code: Select all

Obviously commenting out that stm32f10x.h from stm32.h was a mistake. Does anyone have a working make/ demo for stmf0 discovery?

[beaming]

I would suggest to start from either of the directories in the
testhal/STM32F0xx
They have known to work code samples. You will just need to trace appropriate pins to the ones at your board.

Most importantly they have a proper Makefile which compiles, just fill it with needed extras.

The key part is this one:

#error "Using a wrong mcuconf.h file, STM32F0xx_MCUCONF not defined"

You need to take the file mcuconf.h from an F0 demo, they are different for each family. I suggest you start from an F0 demo then add what you need.

Thanks! I didn't realize there was other demos in the TEST folders

Ive got code running!

No to figure out how to use chibios! Best regards
