Several possibilities: * The MMC support is not enabled in the kernel configuration, or the proper MMC driver. * The MMC device is not described in the Device Tree and/or the support for MMC on this platform is not available. The version of the kernel being displayed is just 3.8.11, which indicates a mainline kernel (which doesn't support MMC on AM335x, as far as I know). However, our beaglebone_defconfig uses a TI custom kernel, which I believe, should show probably show a different kernel version than just 3.8.11. Can you send us your Buildroot .config file?
