flash/ECC issue on an STM32H743.

I'm investigating a suspected flash corruption/ECC issue on an STM32H743.A read from flash address 0x081F0000 consistently causes a fault. The problem is that I'm not fully confident that the fault status registers can be trusted after the event, so

Does the sdmmc1 I/O have internal pull-ups on CMD, D0 D1, D2 and D3?

I’m reading the getting started manual of STM32MP257 (AN5489) and it displays that there are internal pull-ups on CMD and D0, but not CK.Also there is a confusion if the dashed lines means they have internal pull-ups as well.My question is:If CMD, D0

How should the FMAC of STM32G474 be configured to obtain correct calculation data?

Hi,I encountered problems during the development process of using FMAC. To illustrate the problem simply, I used FMAC to implement an RC filter, by which I mean to illustrate the calculation problems of FMAC.RC filter:10K+10nFIts discrete z-domain ex

I3C Controller Initialization Problem

Hello,I have a project that uses I3C to connect a Nucleo-C562RE with an STM32C542CCT6 MCU. The setup was working fine with HAL 2.0.0 but it does not work in 2.1.0. I generated the code with MX2 and I observed that it is identical to the code in the p
