UART4 and SDIO in STM32F103RCT6

[AArt.1]

Fix the stm cube, as these features do not work at the same time.

I lost a lot of time and money while I figured it out

Probably a good reason not to use 13-year old parts in a new design..

The peripheral/pin muxing method lasted one design iteration.

It could be still worthwhile to display a warning in the CubeMX pin editor, instead of subtly punishing developers who do not turn to the errata reflexively.

While we might sometimes think that an ignorant developer deserves it, punishing does not make much sense from a business standpoint :)

Hi @berendi​ ,

Your proposal is shared with our STM32CubeMX team.

I think, I will use DeInit SDIO to use UART, if i need data from sd card, will be init SDIO again

Excuse me, have you solved it? I have this problem, too.
