Original question:

TM4C1294NCPDT: TM4C1294NCPDT interface with SD card

TM4C129ENCPDT: Interface to SD card using SD (not SPI) interface?

Part Number: TM4C129ENCPDT

Is it possible to interface a TM4C129ENCPDT to a SD card (e.g., microSD) using the SD interface (not the SPI interface)? The SD interface seems to bear resemblance to quad SSI but with an additional bidirectional line for command/response. Thanks

    Hi twelve12pm,
    There is an app note that talks about using QSSI for SDCard. However, the app note is under NDA. Can you please contact your local sales office and have the NDA in place before we can make the app note available to you. We can communicate via private message. You can add me as a friend. I will close this thread here.
