Tuning Linux for Embedded Space Applications

on YouTube ↗16m

" summary

CNES adapts Linux to fly as a guest OS inside an extratum hypervisor partition using a Yocto-based distribution and a Fentis layer for inter-partition comms, while enforcing time and space partitioning. A student mission will soon fly a Python AI payload in that Linux guest, proving the approach works; currently two engineers drive the effort. Work includes a minimal user app layer, a PUS communication layer, and plans for a future Linux-based onboard app store.
