I've just tried creating an STM32F767VI FreeRTOS project with the STM32CubeMX in STM32CubeIDE (V1.0.2) rather than the standalone STM32CubeMX (V5.3.0). With this project the offending _sbrk function is in sysmem.c instead of syscalls.c.Memory allocat...

I'm trying to understand why, like FedeRico, my memory allocation calls work when called from FreeRTOS tasks in my STM32F767VI project that uses STM32Cube_FW_F7_V1.14.0 (and hence RTOS V9), but not when the same project uses STM32Cube_FW_F7_V1.15.0 (...

Thanks!Excerpt: As of July-2019, Cube-generated projects using FreeRTOS do not properly support malloc/free/etc and family, nor general newlib RTL reentrancy.

FedericoI have the same problem. I'm using CubeMX V5.3.0 + STM32Cube_FW_F7_V1.15.0 + FreeRTOS V10.0.1.Did you find a solution?Essentially my problem is that all memory allocation functions, including malloc, calloc, and pvPortMalloc, return NULL even...
