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

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.

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, Philipp.

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
