A80 Optimus
The A80 Optimus Board currently refuses to boot from mmc0. Sometimes boot0 is stuck at initializing mmc0, and sometimes the BROM fails to detect the card in mmc0 altogether.

FEL mode
A80 FEL requires the bulk receive endpoint to be changed from 0x82 to 0x81. Patches for this have been merged into sunxi-tools. Please make sure you have the latest version.

To use FEL mode, make sure you have the patched FEL mode boot0 (fes1.fex) and u-boot (u-boot.fex) binaries. You can find them here

How to boot from fel using Allwinner's boot0 and u-boot: cat zImage sun9i-a80-optimus.dtb > zImage-dtb
