cubeMX 4.22 stm32f37xx lib 1.9 comp irq bug

Hello! Code generated by CubeMX  v4.22 using  STM32F3 library v1.9 have the following bug:

When enable comparator interrupt, C code generated in stm32f3xx_it.c use interrupt subroutine titled 'COMP_IRQHandler', while in startup code of the file  startup_stm32F373xc.s this subroutine titled as 'COMP1_2_IRQHandler'. Moreover,  file  stm32f373xc.h consist of  '

#define

COMP1_2_IRQHandler COMP_IRQHandler'.  Therefore, if you change your stm32f3xx_it.c code from  

'COMP_IRQHandler' to 'COMP1_2_IRQHandler - it does not matter.So, the comparator interrupt jump does not directed to the proper location and still point to DefaultHandler anyway.To fix, one should go to edit startup_stm32F373xc.s assembly file, and replace all 'COMP1_2_IRQHandler' occurrences with  'COMP_IRQHandler'

Hi

Khomenko.Sergii

,

On top of CubeMX4.24 and with the same FW library (STM32Cube\Repository\STM32Cube_FW_F3_V1.9.0), I can't reproduce your issue.

In stm32f3xx_it.c, I don't have the interrupt subroutine titled

COMP_IRQHandler.

For F3 library and in

startup_stm32F373xc.s, I have same as you.

Do you sill have your issue on the latest CubeMX4.24?

I have the same issue with STM32CubeMX 4.25.1. and Atollic 9.0.1

 The 'startup_stm32f373xc.s' doesn't sees the 'COMP_IRQHandler' defined alias in '

stm32f373xc.h

'.
