A quick way to hook up a SD card to a STM32 is to use one of those SD to Micro-SD adaptors that come with most Micro-SD's when you buy them. In this video you will learn how to interface a SD-card with FatFS (ExFAT to be exact) using SDIO. However, we are experiencing instability issues with the SD card (not working sometimes), and we haven't been able to resolve the problem despite trying different values for pull-up resistors and using a 10µF capacitor for the 3V3 line. It supports SPI or SDIO communication. We will start by setting up the CubeMx first. im using onboard SD slot and a 32GB micro SD card by PNY.
