What would it take to port a distro to these sbc's

[C0ntract]

I’m the developer of a small GNU+Linux distro. at some point in the future, I’d like to port it to a Libre SBC (Renegade). So I wanna know what it takes, like whats needed to do it? Right now my distro only supports AMD64/Intelx86_64.

Welcome!

I haven’t done myself, but I might be able to point you in the right direction.

First, you need an arm64 image. What is involved in creating that, I do not know, but I’m sure Google does.

Once you have the arm image you’d use this tool to flash the appropriate bootloader:

Libre Computer Flash Tool

Libre Computer Flash Tool on GitHub This tool is currently used to flash bootloaders onto MicroSD cards or eMMC modules exported as USB Flash drives. sudo ./lft.sh bl-flash BOARD_MODEL BLOCK_DEVICE Replace BOARD_MODEL with a model from ./lft.sh b-list Replace BLOCK_DEVICE with a device from ./lft.sh dev-list Please note that this tool may destroy GPT partitions so we recommend that you back up any valuable data on the target device. This tool can also run the eMMC detection routing again t…

I haven’t tried it myself, as the Libre Ubuntu image (and Batocera) cover my needs (and wants). There are some Libre-specific tools you might be missing out on for dealing with GPIO and Device Tree Overlays. They’re available on github, but I’m not sure if you can build them on all 3rd party images.

Hope that helps!

Thanks for the reply. this tool is likely all I need. Now I just gotta figure out how to make the .img file. since the distro is based on debian I’ll try working off a clean debian img to build it.
