sd card not working.

Hello everyone

I am currently working with the ODROID-x2 platform and the U-boot that was using the u-boot by default, but support for the USB driver does not work well. Then I started to use the version available at:

https://github.com/LeMaker/u-boot

The USB works well. Probe the network and SD_CARD memories but now is not working for me. I am using an SD 8Gb.

Serious output is as follows:

U-Boot 2015.04-rc2 (Jun 24 2015 - 10:24:52)

Hi, Alexy.

It seems that sd-card doesn't initialize completely. -> "sdhci_transfer_data: Error detected in status(0x208000)!"

You can enable the MMC debug configuration.(CONFIG_MMC_TRACE) Could you share the log message after enable CONFIG_MMC_TRACE?
