I have tried it, but I get the same: CM-A510>> mmc init CM-A510>> mmcinfo 0 Device: MV_SDHCI Manufacturer ID: 0 OEM: 0 Name: Tran Speed: 0 Rd Block Len: 0 MMC version 0.0 High Capacity: No Capacity: 0 Bus Width: 0-bit In reference to peripherals, only is available USB and Ethernet 0 by default. I am searching in the sources just in case there is something else... but I am afraid I will not find something. >> #define CM_A510_MPP0_7 0x00000033 >> #define CM_A510_MPP8_15 0x00445050 >> #define CM_A510_MPP16_23 0x66664040 By the way, how do you get that resgisters? In my case, I tried to define them as per as Marvell 88AP510 Specification reference. Is it the right place?
