First version based on FreeRTOS 9.0.0

[fpistm]

Based on FreeRTOS-9.0.0 modified by ST and provided within the STM32CubeFw

Portable layer supported dynamically:

• ARM_CM0
• ARM_CM3
• ARM_CM4
• ARM_CM7

Allow user to use his own FreeRTOS configuration file named STM32FreeRTOSConfig.h in his sketch folder.

Added one custom configuration in FreeRTOS configuration file:

/* Begin custom definitions for STM32 */ /* Default (3) Memory allocation implementations (heap_[1-5].c) */ /*#define configMEMMANG_HEAP_NB 3*/ /* End custom definitions for STM32 */ 

This mean the default Memory allocation implementations provided by FreeRTOS is heap_3.c and could be changed thanks the configuration file (configTOTAL_HEAP_SIZE is not use with heap_3.c).

On top of the generic port.c file i have added these lines because with the STM32F429ZI board it always include the ARM_CM0/port.c invece che ARM_CM3F/port.c

#ifndef __CORTEX_M #pragma GCC error "no \"__CORTEX_M\" definition" #endif 

and when i try to build it catch this error!

[fpistm]

Hum... right... Nice shot. I thought I've tested each include... :'(
I don't know what I've done... it misses some includes.
__CORTEX_M is defined by CMSIS

I will add also your guard if __CORTEX_M is not defined
I update the PR with the corrections

[straccio]

Same in portmacro.h

[fpistm]

Yes, seen ;)

[fpistm]

Now it should be ok

[straccio]

Ok, it works good!
I have tested some examples and my Multiplatform domotic sources!

PS: in port.c i have included only "stm32_def.h" no "FreeRTOS.h"

[fpistm]

I include the FreeRTOS.h to have the config included for configMPU_NOT_SUPPORTED.
When supported I will remove this define and replace include by stm32_def.h

[fpistm]

MPU support is fully disabled as it required several config (mainly dependant of the linker script).
Made some cleanup and update README.md
