wow, great! thanks a lot!
will have to test then (if usb works - see also other mail).

afair, at the time i wrote that it didn't / i had troubles with
"Unknown command 'part'"
likely this was fixed some time ago,

You need the attached patch for upstream u-boot/master to work on sunxi
devices, this should get merged upstream soon.

Subject: [PATCH v2] config_distro_bootcmd.h: Enable CONFIG_CMD_PART
The recent changes to config_distro_bootcmd.h require CONFIG_CMD_PART to be
defined, as the default bootcmd now uses the "part" command.
This fixes sunxi boards not booting with v2015.04-rc1.

but I didn't get around to test it.
