      hi Jaehoon Chung

hi Jaehoon Chung
I use the CONFIG_MMC_TRACE in the method
static int sdhci_transfer_data(struct sdhci_host *host, struct mmc_data *data,
                 unsigned int start_addr)
on file sdhci.c.
How did you use the CONFIG_MMC_TRACE?
If CONFIG_MMC_TRACE is enabled, it should be printed messages in mmc.c.
(Try to print all debug messages.)
Then we can check which command is error. I will try to reproduce this.
Best Regards,
Jaehoon Chung

This is the output for debug of method. This output is using  the CONFIG_MMC_TRACE for complete method :

For the CONFIG_MMC_TRACE for the part of method where is throws the error the serial output is the next:

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)
CPU:    Exynos4412@1000MHz

   sdhci_transfer_data: Error detected in status(0x208002)!
   sdhci_transfer_data: Error detected in status(0x208000)!
   Using default environment
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?
