STM32G431RB TIM7 interrupt handling problem

[APett.1]

There is a bug in the file stm32g431xx.h of the archive stm32cube_fw_g4_v130.zip.

It is written there:

/* Aliases for __IRQHandler */

#define TIM7_DAC_IRQHandler TIM7_IRQHandler

#define COMP4_5_6_IRQHandler   COMP4_IRQHandler

After replacing with

#define TIM7_IRQHandler        TIM7_DAC_IRQHandler

everything works correctly.

I'm sorry for my bad english ( Google translated :) ).

I hope someone will find this information useful.

Yours faithfully Alex.

Hi @APett.1​ ,

Would you please give us more details about how to reproduce the error.

Thanks,

Hello @APett.1​ , and welcome to the STM32 Community :)

After an internal check, I found different info that you may want to check out: the defined alias "TIM7_DAC_IRQHandler" is put in place to overcome the differences in the interrupt handlers and IRQn definitions and to ensure codes migration between the STM32G4xx device product.

This point is deployed and highlighted in the release notes of STM32CubeG4 V1.3.0:

• Rename “TIM7_DAC_IRQHandler�? to “TIM7_IRQHandler�? in MDK-ARM startup file for STM32G431xx/441xx/bk1cb devices

So, please ensure to align the start-up file with the new template defined in CMSIS to fix this issue.
