But if your patch is applied, other exynos4412 and exynos using s5p_sdhci don't work fine for SD-card. This case is the specific X2 board. I think schematic is wrong. (I have checked the Odrodd_X-base_Rev_06.pdf) Commonly, SD-detect pin is supplied to always-on power. But odroid-x/u board used the same supplier with I/O line. It's wrong. This is H/W mis-designed problem, not code problem. Well, I will reproduce your problem with X2 board. And if reproduced your problem, I will find other solution, not this. how about? > > Actually it was some other person who encountered this issue with his > Odroid-X2 and booting from SD.

You seems to consider only Odroid based-on exyno4412. Did you test other exynos4412 board?
