Enabling Linux Usage in Space Applications

summary
A prototype implements Linux monitoring on a Xilinx Zynq Ultrascale+ MPSoC to explore safety for space: ELISA project guidelines inform the approach while a real-time master on lockstep Cortex‑A5 cores watches a Linux domain on a Cortex‑A53, refreshes a watchdog, power‑cycles the A53 via the PMU and reloads a secure boot image from SD when faults occur. Results show feasibility but highlight memory integrity risks (TCM vs OCM access, no MPU/MMU determinism) and ongoing work on radiation resilience.
