eMMC boot help
#1
I am trying to get the [unsupported] armbian image to load from eMMC on my pine h64 model b.  The armbian image 

https://dl.armbian.com/pineh64/archive/A..._5.1.15.7z

seems to work like a charm on SD, but I'd like to get the os onto eMMC for faster io.  I have been able to get the Android eMMC and AOSC builds to boot from eMMC on this board, but I'd really prefer Armbian, just because it is a known and will be similar to the rock64 boards I have running Armbian.

However, flashing the image directly onto eMMC doesn't seem to work.  Trying to boot just gives me a black cursor on the serial console.  No activity at all, no u-boot or anything.  As far as I can tell, this should work.  The image seems to have the correct `eGON.BT0` header at the right offset in the image, so I presumed it would have/should have booted.  But no dice

I am new to u-boot, but took a stab at building and installing it onto the eMMC for the h6 anyway, using as a guide: 

http://linux-sunxi.org/Mainline_U-Boot

After following the instructions, building u-boot on a rock64 (targeting the h6), and writing it to the eMMC at the 8kb offset, I pop the card onto the h6.  

However on boot I end up with :
Quote:U-Boot SPL 2020.01-rc2-00035-g3ff1ff3ff7 (Nov 17 2019 - 10:16:56 +0000)
DRAM: 4096 MiB
Trying to boot from MMC2


and it just hangs there.  AFAICT MMC2 is the correct device.
Any pointers?  is there a different branch of u-boot I should be using for the pine64 H6-b ?



One of the complexities is that I can't seem to get the H6 to boot from SD and still be able to read/write to the eMMC device.  Any changes I want to make to the eMMC has to be done on the rock64 and then plugged back onto the H6.  If there is a way to get both SD and eMMC to play nicely on the H6 it would surely shorten the 'round trip' time for making changes.

Any help is greatly appreciated.  TIA
