Hayk Arzumanyan Posted August 28, 2020 Share Posted August 28, 2020 Hello. I have own developed custom boards with H3 processor. One of it works nice, second one doesn't boot.

Hayk Arzumanyan Posted August 31, 2020 Author Share Posted August 31, 2020 My boards are 1:1 copy of Orange Pi One. It's not unknown board. And Armbian is Buster server stable version from https://www.armbian.com/orange-pi-one/ Link to comment Share on other sites More sharing options...

Hayk Arzumanyan Posted August 31, 2020 Author Share Posted August 31, 2020 Werner it's true. I'm not here to lie ))) I'm not asking what do you have. I'm asking do you know FDT creation failed problem what does it mean??? I haven't only these two boards. I have a lot of 1:1 copy Orange Pi One boards they boot fine. Only in one board it happens. And I don't understand FDT creation failed it's RAM or H3 processor problem. Link to comment Share on other sites More sharing options...
Werner Posted August 31, 2020 Share Posted August 31, 2020 I serioulsy don't wanted to imply you are lying. Heaven forbid! For the issue itself I unfortunately cannot answer your question since I don't know how and why this happens. However Igor is right anyways. it is a board that is not supported since it is custom made so it is correct to move the topic to general discussion / p2p help.
