STM32F469 use RTOS ERROR

Question

Hello,

i want to run the RTOS on the STM32F469 in the example code I need to define EW_USE_FREE_RTOS = 1 that the RTOS function will be used but I get some errors.

I include the RTOS in the CMSIS package then i need to remove the startp_stm32f469xxx.s because ther are multibly defined.

After that I get Errors like that:

Have I done something wrong?

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
