How to compile Gentoo for Orange Pi Zero 2W?

[ivanbrash]

Orange Pi Zero 2W is a Chinese alternative for Raspberry Pi Zero 2W with Allwinner H618 CPU and Mali-G31 GPU, which is more powerful than Raspberry Pi Zero 2W. And I would like to ask you, is the instruction for Raspberry Pi suitable for Orange Pi Zero 2W?

ivanbrash,

Welcome to Gentoo.

The general concept in the Raspberry Pi Install Guide is valid, as are the Gentoo parts of of the setup.
The idea is to put a vendor kernel under a Gentoo stage 3 and set it up to boot.

You will need to replace the Raspberry Pi content of /boot with whatever a Orange Pi Zero 2W requires.

Further, you won't be able to build much on an Orange Pi Zero 2W.
See Further Reading. The alternatives are Cross compiling and/or a QEMU chroot.
They both run on $RANDOM_ARCH but generate code for your Orange Pi Zero 2W.

Hmm ... there is a 4G version. That has the RAM for most builds.

I'm have been testing Orange Pi Zero 2W in Geekbench 5 and it is similar in performance to the first laptop Core 2 Duo and KDE Plasma 6 works well on it(tested on Manjaro ARM Build for Orange Pi Zero 3/2W/2 from junari). For compiling a Gentoo for this SBC I have the mini-PC on Ryzen 7 6800H which purchased on Aliexpress for 500$.
