SDIO/SDMMC Problem with micro SD card FR_NOT_READY error
Hello, I am wanting to configure the SDIO peripheral on my STM32F407G-DISC1 to write a file to a 16GB type 10 micro SD memory. The problem is that I am receiving the FR_NOT_READY error when I want to create a file and I don't know what the problem is. I have attached my code.
