Firmware build instructions

Hello,

Where are the latest firmware(I-loader, UEFI/EDK2, ATF) build instructions ? all the documentation links only point to AOSP build instruction and the instructions from old links don’t seem to exist anymore. Is there no more support for building firmware from source for the LeMaker 6220 board?
I’d like to customize the firmware to be able to boot up a custom OS. Any help appreciated.

Which old links are you referring to?

You can try https://github.com/Linaro/documentation/blob/master/Reference-Platform/Releases/RPB_16.06/ConsumerEdition/HiKey/BuildSourceBL.md maybe.

@vchong, thanks. I was referring to the links given here: Instructions to build kernel and firmware from source.
Anyway the link you presented is what i was linking for. The instructions in the link are the latest instruction right ?

You’re welcome. Things get moved around every once in a while but afaik that is the latest.
