    T41 SD card port as periferal interface?

    If the SD card port is mapped to SPI2, the port can be used for other devices...has anyone made any any shield\hat equivalents that interface via the micro-sd connector?

    You always can use SDIO protocol (even if nobody has done so far AFAIK)

    Sparkfun has a micro-SD sniffer that can be used to access the 8 pins. The design is also available at OSH park:


    You could repurpose some of the micro-SD extender cables available, soldering in wires to connect the 8 pins.
