a20 doesn´t boot from EMMC

Hi!
I look for this topic in every place at the internet but all of the topics are not related with my problem.

I have a custom board based on the Lime2-emmc.
It can boot from SD, but when I tried to copy the same u-boot-sunxi-with-spl.bin to the emmc  and try to boot, nothing happends, the screen is empty.
dd if=u-boot-sunxi-with-spl.bin of=/dev/mmcblk1 bs=1024 seek=8
boot from SD

When it boots from SD the u-boot shows both (SD on MMC0 and EMMC on MMC1)
I´m using the A20-OLinuXino-Lime2-eMMC_defconfig with some mods to my board.
My emmc is unit is  KLM8G1GEME-B041 and is connected to the board like the emmc unit is connected to A20-OLinuXino-Lime2_Rev_G

I did a hexdump on the SD and MMC and it looks the same with the "eGON.BT0" tag in the right position.
