Checking older U-Boot releases shows that it used to work in v2014.10, and bisecting points to the commit a276172cf32386c211c75638f6bf3c0d59ba03ba ("arm: exynos: fix the div value for set_mmc_clk"): http://git.denx.de/?p=u-boot.git;a=commitdiff;h=a276172cf32386c211c75638f6bf3c0d59ba03ba Reverting this commit resolves the problem and the SD card starts working properly. As an extra test, I also tried to add debugging print at the end of the exynos4_set_mmc_clk() function, so that it calls exynos4_get_mmc_clk() with the original 'dev_index' and reports the resulting mmc clock speed. After reverting the patch, the reported value is 50MHz. Before reverting it, the reported value was 100MHz. This is a Transcend class 6 SDHC card. Is this enough information or should I check something else? -- Best regards, Siarhei Siamashka
