I'm also newbie and I'm working on adding a sdhci_acpi driver for Intel's Atom SoC. I wonder if your device would work with the existing sdhci_pci driver. Maybe it just a matter of adding the device id and possibly setting some quirks or you might have to write a new driver for the host controller? For me it's a bit tricky because I have to communicate with the card using GPIO before it can be detected. There is a driver in FreeBSD for reading and writing to a mmc so maybe it is just a matter of connecting that to the controller. Searching the Linux source for the device id to see if there is a driver is a good idea. For FreeBSD source check sys/dev/mmc/ sys/dev/sdhci/ There is also a ongoing project to rewrite mmc to use cam. Maybe good idea to check that as well. https://wiki.freebsd.org/SDIO On Friday, February 19, 2016, Larry Rosenman <ler@lerctr.org> wrote: > On 2016-02-19 22:25, Gary Corcoran wrote: > >> On 2/19/2016 11:08 PM, Larry Rosenman wrote: >> >>> On 2016-02-19 22:05, Mehmet Erol Sanliturk wrote: >>> >>>> On Fri, Feb 19, 2016 at 7:58 PM, Larry Rosenman <ler@lerctr.org> wrote= : >>>> >>>> Great.
