Rock Pi 4: Does ArmBian build their own U-Boot and TF-A binaries?

[lag-linaro]

The binaries supplied with the ArmBian release for the Rock Pi 4 work great.

 

However, when I try to build my own from Mainline sources, I see lots of booting issues.

 

Do you use Rockchip provided binaries, or are they built from scratch?

 

Any help would be gratefully received.

Thank you!

I know it works best. We have sponsored this development for the ones that sold you hardware. You can make a donation here. Before you burst out with one million dollar questions that can only be answered to business clients, take a look at FAQ.

BTW. This is open source, so we are not hiding anything. Just if you are not covering our time, we can't help. I hope you are able to understand that.

you need goto LibreELEC, it supports upstream TF-A for a lot of board.

OP place this question on many forums and chat channels so I am sure he found it by now.

AFAIK we also do but he can also look into the code like anyone else.

I found the answer to my question by studying the code.

 

Turns out the Rockchip TPL blob is required to make the board reliable.
