@blood Thank you for documenting your progress. I recently got hold of a Helios4 and also want to get it to boot directly off SATA. I'm currently working on getting uboot for the Helios4 updated in Armbian. Let's collaborate and maybe do the same for the Clearfog?

Mangix, are you still around? Where is the code you are referring to in openwrt? I see exactly one commit in 2020 about the Helios4 and then nothing after that. I also don't see any specific patches applied.

@Sergey Lepeshkin thanks for the information.After a while search for soldering shops i didnt have any results, it seems like there is no soldering shop in my city (there are but very far away). I was expecting a alot of them since im in the center. What to do now?

Have you looked into hosting your own deb package cache locally? You can set the MANAGE_ACNG build switch for that purpose and have a prepopulated apt-cacher-ng proxy in your LAN. Let us know how it goes.

@Deoptimhow to build the current u-boot ? and how build MiniLoaderAll.bin?
