If you're using exynos4412 board, you can choose sdhci or dwmmc controller for eMMC, not SD/SDIO. And in my experiment, dwmmc controller is more appropriate than sdhci.(ex, performance) >> >> Thank you for your help > > I'm not really sure - the compatible string for that node is: > > compatible = "samsung,exynos4412-dw-mshc"; > > which is different from what exynos5 uses. As i know, Some register are difference..but i know it doesn't implemented for those registers at u-boot side. If it should be implemented for upper mode than DDR50, it needs to check the compatible.
