Hello,
in our current STM32F469_Discovery build environment FreeRTOS is only supported with gnu make.
I asume, that you are using Keil µVision.
To add FreeRTOS support to the µVision template project,
following steps have to be done:
* define EW_USE_FREE_RTOS = 1 (as you already done)
* add the FreeRTOS source files below folder:
'STM32Cube_FW_F4\Middlewares\Third_Party\FreeRTOS\Source'
(list.c, queue.c, tasks.c, timers.c, cmsis_os.c, heap_4.c,
and 'port.c' from sub folder \portable\RVDS\ARM_CM4F)
* add the FreeRTOS include pathes below 'STM32Cube_FW_F4\Middlewares\Third_Party\FreeRTOS\Source':
/portable/RVDS/ARM_CM4F
/CMSIS_RTOS
/include
Best Regards,
Martin
