Applied this on my Odroid C2, and it worked OK when installed on the SDcard, but failed when installed on the eMMC module:
Oh, reading this again you meant that you put u-boot directly on the eMMC? Ok then, something is wrong when using the driver with the eMMC.
Yes, I installed it directly on the eMMC, using the micro-sd adapter, and following the same instructions as for the SDcard..
Could you try with this patch?
