Linux Kernel Module Cheat

26.11. Buildroot hello world

This repo doesn’t do much more other than setting a bunch of Buildroot configurations and building it.

The minimal work you have to do to get QEMU to boot Buildroot from scratch is tiny if, about 4 commands!

Here are some good working commands for several ISAs:

These can come in handy if you want to debug something in Buildroot itself and possibly report an upstream bug.
