Hi,

I'm trying to build an ''empty'' project generated by CubeMX using FreeRTOS and gcc for STM32F103xB. I'm using the latest CubeMX (4.14.0) and latest HAL (1.3.1). I've successfully built projects using CubeMX, HAL, gcc that work, I just get errors when I'm trying to use FreeRTOS. I've added to the include path (-I) FreeRTOS/Source/CMSIS_RTOS FreeRTOS/Source/include FreeRTOS/Source/porteble/GCC/ARM_CM3 I've included in the build: FreeRTOS/ FreeRTOS/Source FreeRTOS/Source/CMSIS_RTOS FreeRTOS/Source/portable/GCC/ARM_CM3 FreeRTOS/Source/portable/MemMang/heap_4.c + all the other stuff needed to make a CubeMX/HAL project works. but I get undefined reference to `pxCurrentTCB'    port.c undefined reference to `vTaskSwitchContext'    port.c BTW if anyone from ST is listening it would be nice if you didn't include in the main.c template the cmsis_rtos stuff so one would be free to chose to use FreeRTOS directly or not without having to edit main.c every time. #stm32f1 #cubemx #freertos #gcc
