> I understood more clearly...Your target for using is sdc0(eMMC), right?
Yes

Now i have checked det pin on my board. I use standart A20-OLinuXino-Lime_defconfig with my board.
So PH1 is pull-fown. No changes if just remove det pin

U-Boot SPL 2016.11-rc1-g4dc34be-dirty (Oct 12 2016 - 18:12:37)
DRAM: 512 MiB
Failed to set core voltage! Can't set CPU frequency
Trying to boot from MMC1
mmc_bread: Failed to read blocks
mmc_load_image_raw_sector: mmc block read error
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###



Then , i removed det pin from config and build again. Burn it to emmc(sdc2) on marsboard and tried to boot this board with mainline u-boot, not 2014 as before and get this.

Something new, error code is 19 ) Looks like it see that no card on sdc0 and found emmc on sdc2, but fails.
Same code on my board never tries mmc2, so it part works

I hope on your help, thank you very much
