I am using the Freertos v202112.00. While compiling the standalone demo project of CORTEX\_MPS2\_QEMU\_IAR\_GCC, I am getting compilation error because freertos.h ,task.h included in main.c but don’t have these two files in the package of CORTEX\_MPS2\_QEMU\_IAR\_GCC. Even SMM\_MPS2.h file is missing, which is being included in IntQueueTimer.c ---

Are you compiling the provided project itself or did you make changes to it? Can you share the compiler output? Any reason for not using the latest version? ---

I downloaded FreeRTOSv202112.00. In that I am trying to build the Demo project : CORTEX\_MPS2\_QEMU\_IAR\_GCC on VS code.

As per the procedure, it is getting imported in VS code and I am building the cortex\_Mps2\_QEMU\_IAR\_GCC project. I launch the vs code and tried to build . I am getting FreeRTOS.h and task.h is missing in the project. It is having the make file too. Else please provide me a demo application for cortex\_MPS2\_QEMU\_IAR\_GCC. ---

What is the Operating System running on the machine on which you are running VSCode? It is Linux (such as Ubuntu) or Microsoft Windows? Also, can you share the complete output in the _Terminal_ tab (not in the _Problems_ tab)? ---
