SD module with SPI on STM32F401RCT6

[Demiañ]

I'm doing a project with a SD card, but I have not been able to make it work.

I'm using an STM32F401RCT6 and a Micro SD Card Adapter (HW-125), I want to connect them via SPI. I've followed several tutorials online, but I haven't been able to get it to work.

Do you know any tutorial or resource that could help me?

Welcome to the forum.

You'll need to give some more details of what, exactly, you've tried - both hardware and software - and what testing & debugging you've done.

Lots of resources here:

Not sure the HW-125 is ideal, the one that comes up takes a 5V input, has a regulator to get to 3.3V on the card side

The STM32F4 isn't running at 5V, so the Arduino / 5V adapter isn't helping you here. The WaveShare MicroSD adapter is a better choice. Pull-up's on the right pins, and a socket sense pin.

ST has an SPI SD Card example under the AdaFruit / Nucleo board support.
