I'm still not sure what the right approach is...

Doing what I did (boot into the Ubuntu shipped with the original
firmware and use dd(1) to overwrite the firmware image) almost
certainly isn't.

I suppose the best approach would be to use the "rockusb" mode to
overwrite the eMMC firmware with a "pure" U-Boot image would be the
way to go, but I didn't get that to work using OpenBSD's libusb and I
didn't have a Linux box around.  I plan to come back to that but not
before november :(.

Cheers,

Mark

I would rather see people discouraged from going down that road as
well… or to document this as a deprecated approach only.

Would you be willing to submit a patch with documentation for this?

Thanks,

Hmm,

Do we really want to push people in this direction, using propriatary,
closed-source binaries?

The "pure" U-Boot approach that is currently documented works just
fine.  The only problem is that the firefly-rk3399 by default boots
from eMMC.  And the first-stage bootloader only recognizes SD-cards
with the propriatary loader.  So the trick is to wipe the firmware
stored in eMMC or replace it with U-Boot.

[U-Boot] [PATCH 1/1] rockchip: provide installation instruction for Firefly-RK3399.

[Heinrich Schuchardt]

Unfortunately installing U-Boot on an SD card for the Firefly-RK3399
is not trivial.

I could not get U-Boot running with SPL.  So I ended up using the
Rockchip miniloader.

Adding a README hopefully will give other users an easier start.
