This is MMC/SD disk driver for Freescale Kinetis and iMX. https://sourceforge.net/projects/ecosfreescale/files/devs/SDHC/ Upper layer (based on SPI MMC driver) and HW dependent (Freescale) parts are placed in separate packages. Jerzy, can you see if STM support can be added? Note: The aim of this project is support for MMC/SD memory cards (I.E. disk drive) SDIO is out of scope. Comments are welcome.
