No, I did not start. Things that kept me from starting: - other work :-) - I think we don't have a clean SDIO interface, if we have a defined SDIO interface at all. - there is no app/sdio challenging and demonstrating basic functionality of a SDIO driver to allow driver development and verification. So please, go on. If you need help with the basic STM32 infracturture, like pin multiplexing or DMA, please let me know. SDIO is special w.r.t. DMA, as SDIO determines the number of transfers while in all other cases the number is set by the program. The STM32 DMA interface may not cope with that feature.
