Dev/Embedded

General

• Do not use Yocto or OpenEmbeded (or their predecessors).
• Open-source matters (or why I don't use RaspberryPi boards)

Cross-compilation

Setup cross-compilation environnement on Devuan GNU/Linux

Linux Kernel (and bootloader)

Build your Linux Kernel and bootloader : generic informations, may need specific versions or patches depending on the board you are using.
Here are direct links to :

• the page dedicated to the U-Boot part
• the page dedicated to the Linux Kernel part

though you really should consider reading all the information you will find on the main page about building your system from scratch.

Rootfs and Userspace

Create and configure Rootfs :

• Busybox
• Devuan rootfs : creation from scratch and configuration

Rootfs backup or copy (doing it the right way)

Embedded targets

• BeagleBone boards
• OrangePi boards
