Error compiling freertos for nucleo stm32f767

Question

I have generated code using cubeMX and while compiling it gives me the following errors. I have already tried several fixes but none of them is working.

    /tmp/ccvxTV8U.s: Assembler messages:
    /tmp/ccvxTV8U.s:758: Error: selected processor does not support `vstmdbeq r0!,{s16-s31}' in Thumb mode
    /tmp/ccvxTV8U.s:760: Error: instruction not allowed in IT block -- `stmdb r0!,{r4-r11,r14}'
    /tmp/ccvxTV8U.s:782: Error: selected processor does not support `vldmiaeq r0!,{s16-s31}' in Thumb mode
    /tmp/ccvxTV8U.s:784: Error: instruction not allowed in IT block -- `msr psp,r0'

I'm using the NUCLEO-F767ZI with a STM32F767

have you tried compiling it using: STcubeide, keil or Atollic® TrueSTUDIO? Seems to me that your mcu configuration is wrong. — Tarick Welling
You should check where ccvxTV8U.s comes from (it is from freertos? are you sure?). Probably it shouldn't be compiled. Compiler flags seems right. (-mcpu=cortex-m7 -mthumb) — Damiano
Re-run cmake with CMAKE_VERBOSE_MAKEFILE=TRUE and re-run make VERBOSE=1 and show the compilation commands including compiler options. — KamilCuk

 file(GLOB_RECURSE SOURCES "Middlewares/*.*"

You are compiling FreeRTOS for all possible implementations for all possible cpus, so you are also compiling sources not compatible at all with your current cpu. You should compile sources only for your destination cpu.

That would most probably be, assuming the folder Middlewares is taken from cubemx:

 file(GLOB src1
      Middlewares/Third_Party/FreeRTOS/Source/portable/GCC/ARM_CM4F/*.c
      Middlewares/Third_Party/FreeRTOS/Source/*.c
 )

And add only the needed include path:

 target_include_directories(YOUR_TARGET PUBLIC
      Middlewares/Third_Party/FreeRTOS/Source/include
 )
