u-boot build options

[stalker37]

Hello.
Can I see build options for u-boot on running image?
Do I understand correctly that the answer is  point to /usr/lib/u-boot/$BOARD_defconfig  ?

That is build config, yes, but you need correct sources (usually certain mainline tag + patches) ... we don't pack u-boot sources, only kernel. So what you are trying to do is not supported.

Thanks for the answer.
Patches I can see at  https://github.com/armbian/build/tree/master/patch/u-boot ?

I'm just trying to figure out how it all works. Hobby.
Sorry for my english.

Perhaps start here https://github.com/armbian/build#build-tools-overview and dig into the script. Most of the code is self explanatory. Also documentation will help to some point https://docs.armbian.com/Developer-Guide_Build-Preparation/
