ChibiOS Free Embedded RTOS

Hello,

I just downloaded Chibios 16.1.7 and I try to compile some demo examples. For example "RT-STM32F746G-DISCOVERY". I invoke "make" command inside of project directory and I get this error:
Linking build/ch.elf
ChibiOS/os/common/ports/ARMCMx/compilers/GCC/ld/STM32F746xG.ld:1: undefined symbol `__main_stack_size__' referenced in expression
collect2: ld returned 1 exit status
make: *** [build/ch.elf] Błąd 1

Could anyone help me?
I don't know what to do with that issue.

Hi,

I am unable to reproduce the issue compiling with ChibiStudio, which toolchain are you using?

Giovanni

Hey,

I am using gcc version 4.5.2 (Sourcery G++ Lite 2011.03-42).

Thank you for your time.

Hi,

I haven't tested that compiler in ages, please try with this one: https://launchpad.net/gcc-arm-embedded

It is the most supported nowadays.

With toolchain that you told all working properly. It's strange because I use my old toolchain to compile projects based on ChibiOS 2.6.7 and it works.
Anyway thank you very much for you help.

Best regards,
Franek

Hi,

We used to use CodeSourcery too but it is no more updated frequently and that other compiler is maintained by ARM people so the choice is obvious.
