 |
|
| 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$. |

And how to flash u-boot without damaging the partition table? |

If you are working with Allwinners SoC, this site is useful: https://linux-sunxi.org/

You can create a partition in the right place and then dd into it. This way, you can be sure you won't overwrite anything important. |

And which SAFE_CFLAGS should I use to compile Gentoo with maximum optimization for the Allwinner H618 processor? After all, I'm going to use the mainline Linux kernel with some patches to make everything work. |

| Probably something like: "-march=armv8-a -mtune=cortex-a53 -pipe -O2". |
