Posted on May 28, 2018 at 09:52Hello, i am trying to use the mass storage interface with my SD card by the help of the stm32 cube. My mcu is stm32f405 and i'm using SDIO 4 bits + USB full speed stack. I am able to see the device and read all the files (big files and small files) when i plug the usb connector of my board to the desktop. However, I am unable to write files although when writing to the SD card it shows that write is complete. Has anyone encountered this issue?
