[gentoo-user] Gentoo on an odroidH2 using eMMC

[Bill Kenworthy]

Hi,

     has anyone successfully set up Gentoo on an odroidH2 using an eMMC?

I have got as far as the pivot-root (so it loads and executes the 
intramfs) but fails to find the /dev/mmcblk0p[01] devices.  The sting is 
I copied the files it to a USB key and that boots fine!  It appears that 
the eMMC initramfs is not loading the modules for the eMMC where as the 
USB version is (and they are using the same file!).  I have tried 
manually loading the modules from the efi shell I think are involved but 
no mmc devices appear.

The eMMC runs uefi from GPT partitions using refind but as the bios 
finds and loads the ramdisk I think thats working ok (I did a working 
ubuntu install first, then reused those partitions.) I can use usb early 
boot to pivot to the root on the USB key but so far cant pivot from the 
eMMC initramfs to real_root. Ubuntu uses grub, which I tried first but 
had even less success with that.

Hints anyone?
