it seems that CubeMX32 generates an incorrect project configuration for my STM32F429ZI discovery board when I choose to add FreeRTOS to the project. I got errors such as selected processor does not support Thumb mode as described in this post but my solution had to be slightly different because the MCU Settings do not have the mentioned drop down menus:
My solution was to add “-mfpu=fpv4-sp-d16 -mfloat-abi=hard” to both “MCU GCC Compiler->Miscellaneous->Other Flags” and “MCU GCC Linker->Miscellaneous->Other Flags”. Why are these FPU dropdown menus not available under MCU Settings? CubeMX32 generating an erroneous project configuration in the first place is another problem, but not on your side.
