Thanks Marcin. Unfortunately, that doesn't quite get me there:

modprobe sdhci-of-arasan sdhci: Secure Digital Host Controller Interface driver sdhci: Copyright(c) Pierre Ossman sdhci-pltfm: SDHCI platform and OF driver helper

No mention of mmc0. :-(

modprobing mmc_block doesn't seem to help.

Does anyone know which kernel driver is required to access the MMC port? I can access it from u-boot, but the kernel I'm using doesn't seem to load a driver for it (4.4.44 mainline). Any hints as to what driver is needed? Generic mmc_core/mmc_block don't seem to result in it showing up.

But I do not have card inserted so no idea does it works. _______________________________________________ Arm-dev mailing list Arm-dev@centos.org https://lists.centos.org/mailman/listinfo/arm-dev
