How to stop STM32Cubemx from generating code for specific handlers

I am using Keil MDK to setup a project for STM32 devices. STM32cubemx is integrated into Keil and can be used to generate a skeleton for the project (main.c, stm32XX.c, .h files and stm32CubeMX.ioc, etc).

This is helpful but some of the generated code contain duplicates of some handlers, like "void PendSV_Handler(void)". How do I stop STM32CubeMX from generating these defines?

Hello @Syn_BE​ 

First, I apologize for my late reply.

If I did understand well the situation; you need that CubeMx stop generating the interrupt handlers, you mentioned.

If so, under System Core --> NVIC --> Code generation you will find the list of all the interrupt handlers. You uncheck those you don't need CubeMx to generate:

Hello @newdev​ 

First let me thank you for posting.

I trying to reproduce the same behavior you encountered but it works fine from my side.

To be able to push further the analysis could you please provide a minimal project which show the problem.

I'll be waiting for your feedback.

Thx.

Semer.

I have the same problem here.

I use CubIDE 1.10.1 with integrated CubeMX 6.6.1 for STM32G474.

  • I use "my own" FreeRTOS, not the one of CubeMX (Middleware FreeRTOS is "disabled")
  • I use "generate as a pair of '.c/.h' files per peripheral"

As @newdev​ wrote:

CubeMX is generating handler functions (in file "stm32g4xx_it.c") for

  • PendSV_Handler
  • SVC_Handler
  • SysTick_Handler

which collide with the handlers of "my" RTOS.

How can I prevent the generation of these functions in CubeMX?

Best regards, Andy
