Hello,

I’m trying write Wrapper Class for FreeRTOS with ARM GCC on eclipse platform.
I had worked same Wrapper Class on Keil MDK-ARM v5.14.

I’m using stm32f303vc which is cortex-m4 and it has got Hardware FPU.

So I have included Source\portable\GCC\ARM_CM4F port files to my project.
I dont invoke any freertos functions in my main.cpp just compiled empty project.

Here is my compilier output:

This is a compiler command line problem. The compiler is complaining about floating point instructions because you have not told it that the processor has a floating point unit.

I’m not sure if the flags in this post are correct for you, but you get the idea:

Thanks for your help It worked.
Here is my Processor settings:
-Float ABI = softfp(I was trying with hard option because stm32f303 has got hard-FPU unit. I dont figure out yet why this option isn’t working.)
-FPU Type = fpv4-sp-d16
-Instruction set = thumb

So after that correction I have worked simple led blink example with using C++.
Anyone can take a look my source code from bitbucket(https://bitbucket.org/Namcho/freertos_gcc_stm32f3/src). The led blink example written in Demo.cpp class file.

Then I have tryed to do same think for FreeRTOS but I failed.

That is a linker error not a compiler error. Somehow including that line has increased the RAM footprint by more thank 30K.

Yes, I examine mem.ld and sections.ld linker file but I cant figure out anything yet.
Could you give me some hint to solve that issue.

First see if it is the C++ that is causing the linker error or just that you are creating a task which then brings in the heap array. Try replacing the call to ledObj.create with a direct xTaskCreate() call. Do you still get the linker error?

Yes I’m still getting the linker error(36520 bytes overflow). I’ve tryed this in main.cpp file.

In addition I’ve created C project then compiled just xTaskCreate(vTask1,“LED1”,configMINIMAL_STACK_SIZE,NULL,1,NULL); function

Here is the output:

As you see just overflowed byte quantity is incresed to 36408 bytes in C.

Which heap_n.c file are you using (http://www.freertos.org/a00111.html)?
What is configTOTAL_HEAP_SIZE set to?

Regards.

I wasn’t looked TOTAL_HEAP_SIZE.

Here is the default defination:
#define configTOTAL_HEAP_SIZE ( ( size_t ) ( 75 * 1024 ) )

So it was 75k bytes

I’ve reduced heap to 1k now everything is alright.

Thanks for your helps.

As configTOTAL_HEAP_SIZE is making a difference I guess you are not
using heap_3 - in which case you will need more than 1K. Increase the
size gradually until you get linker errors again, then reduce it a bit
so it links. After that you can use xPortGetFreeHeapSize() and
potentially xPortGetMinimumEverFreeHeapSize() to determine how much heap
space you are actually using, and adjust configTOTAL_HEAP_SIZE accordingly.

Regards.

Yes I’m using heap_4.

Thank you for this important information.
