Hii,

i just stared my new project with freertos, i am using STM32F051 M0 controller.
but i cant find any demo sample with FreeRtos not even on FreeRtos site.
There is M3 demo codes for STM controller i just tried to port M3 To M0 but FreeRtos M3 Demo Application does not port to M3.
for Development I want to use Keil not others.
So how to Start with STMM0 with FreeRtos.

There is a demo for an ST Cortex-M0 part here:

It is using IAR. The latest release version of FreeRTOS does not have a Cortex-M0 port for Keil, but the latest head revision in SVN does - you can take the code out of SVN for now. It will be released soon.

The Keil port is in SVN - link in my first post.

Error: L6406E: No space in execution regions with .ANY selector matching heap_2.o(.bss).

This just looks like you have overflowed the amount of RAM in your project. Try lowering the value of configTOTAL_HEAP_SIZE in FreeRTOSConfig.h, removing any heap defined by the project itself, and lowering the stack allocated to main() to about 400 (also defined in the project itself).
