His solution? The Raspberry Pi series of chips has a special function on a bunch of the GPIO pins that make it easier to talk to SDIO devices. SDIO is an extension of the SPI-like protocol that ...

During the development of our SD Host Controller we were able to carry out interoperability testing of the IP core within hours of synthesizing the core to FPGA. Likewise in this project where we are ...

Need additional, custom IO for your Raspberry Pi? Adding an FPGA is a logical way to expand your IO, and allow for high speed digital interfaces. [Eric Brombaugh]’s Icehat adds a Lattice ...

The FPGA development board is tested with all major SD cards, SDIO commands, and eMMC devices. The IP is in volume production and has been successfully implemented in a wide range of applications.
