Question

Eclipse/workspace configuration for custom boards

Hello everyone!

I'm new in the stm32 world and I have to say, I realy like it!

I am under Ubuntu and I use '

Eclipse System Workbench

' pre-configured IDE. I only use standart-stm32 library for now.

I had some practise on a stm32f0-discovery board (no problem here), but now I have to work on a

stm32f107vc UC on a custom board

. When I created my new project(on eclipse system workbench), I also created a new board with the appropriate UC.
  • My first problem (and workaround): Interruptions made my code stop , workaround -> I modified the file 'startup_stm32.s' and added Interruptions to my vector table 'g_pfnVectors', it works for now.
  • My second problem:

    USART TX sending bad characters:

    When I send 'Hello\r\n' through USART, I read 'ZE]F�' on the TX. But if I make a new project, selecting a NUCLEO stm32F103 board, and I use exactly the same code to program my stm32f107 board, it works....

So my question would be:

How to configure my project in the case of a Custom board (considering I am working with eclipse IDE, or not)?

I would be very thankfull if anyone could give me any idea, or track to follow... and I hope my question is clear enough.

Alex

    Thanks for the answer. Well I don't think it is, as I said, the exact same code will work on an other board description.

    I found an other workaround, I changed a preprocessor option of my compiler from 'STM32F10X_CL' to 'STM32F10X_MD' and now I receive the good characters from the stm32.

    The strange thing is that I am working on a stm32f107 µC, wich is a 

    Connectivity line device

    so it should work with the 'STM32F10X_CL' option.

    I dont understand whats going on...

    If someone has an idea, it would be very appreciated!!

    the exact same code will work on an other board description.

    Only if it would be the same *binary* would it deserve the 'exact same code' label. I doubt this is the case.

    So show us how do you set the system clock, or check it through outputting to MCO and measuring it.

    In fact it's the APB setting not the system clock as such, so you might also investigate that.
