Block Device Driver for Freedom K66F internal SD Host Controller
Has anyone built a Block Device Driver for the Freedom K66F internal SD Host Controller? The Freedom K66F has a MicroSD slot and the chip includes a native Secure Digital Host Controller. Since this has the four-bit data bus to the MicroSD, it should be able to perform much faster than access via the SPI-based SDBlockDevice driver. I found several references to the internal Host Controller in the forums but couldn't find any corresponding code. For what it is worth, it looks like both the Freedom K64F and the Hexiwear have the internal SD Host Controller as well and could also benefit from a faster Block Device driver. Thanks.
