Problem with boot from emmc

[lombyp]

Hi everyone, every time i try to boot the system from the emmc, I always get the same error:
[2.538703] sunxi-mmc 1c11000.mmc: data error, sending stop command
[3.541959] sunxi-mmc 1c11000.mmc: send stop command failed

does anyone know how to solve this problem?

Is this the same as this (see post #5) https://www.olimex.com/forum/index.php?topic=8193.msg31456;topicseen#msg31456

Hello JohnS and thanks for your answer.

It is not possible to boot directly from the eMMC since that part of the boot process does not work well with newest 5.1 eMMC memories. The eMMC boot code is old and only for older eMMC (up to 5.0), unfortunately such memories are not easy to find anymore.

Hence SPI->eMMC boot. All Olimex boards that have eMMC also have SPI.

could you explain me step by step what to do and/or enable?
