Using Linux as an Embedded OS for the Space Industry
summary
CNES-led project produces a Yocto-based distribution delivered June 2022 and demonstrates Linux running in Xen partition with an initramfs image on Raspberry Pi and Zebu hardware; proof-of-concept includes a basic SpaceWire driver on Zebo board and partition communication via a hypervisor, but work flags hard limits: Linux needs an MMU, images run from RAM, footprint and vendor BSP fragmentation make maintenance heavy, and the open community model stalls because large contractors resist upstreaming proprietary code.
