STM32H7A3 CubeMX no alternate function settings for PC2_C and PC3_C pins

Jack123 · ‎2021-09-15

For STM32H7A3VIT6, in the latest CubeMX software I cannot assign alternate functions to the PC2_C and PC3_C pins. But according to the datasheet it should be possible by closing the analog switches to PC2 and PC3 by modifying SYSCFG_PMCR registers.

I've checked the alternate function settings are indeed present for older STM32H7 lines. But not for STM32H7Ax/Bx. Is this a bug in CubeMX or a hardware limitation?

I've rechecked the version and found out that I'm using 6.1. After upgrading to 6.3 it works as expected.

Thank you very much for your help!

Welcome to the STM32 community @Jack123 !

I truly couldn't reproduce this issue.

So can you please provide me with your .ioc file ?

Best regards,

Mouadh.

I think this was an issue in older CubeMX versions. Latest is v6.3.
