I’ve been working on getting my own os to boot from eMMC on this board although I can only get it to boot from a sdcard successfully. I’m currently doing this through uboot. The reason I can’t get this to boot is that it seems that uboot does not support writing to eMMC anymore ? I’m assuming this because I don’t believe I am doing anything wrong yet as I’m following the instructions from the imx6 site and I’ve worked a bit with uboot before.
So my main question is… should this work? If not is there a how to on building a new uboot with the options required to write the emmc and get uboot written to the emmc location. Should I be doing this differently.
Could you please specify your U_Boot version and what exactly you did and what command you were using ?
Sure… sorry I’ll run through things again and show you exactly what I’m seeing. For now this is the uboot version.

That version supports writing to eMMC. So what exactly commands did you use to store your OS to eMMC and how you find out that it was not stored?
