Running Linux on Constrained IOT Device

summary
Demonstration of a Linux-based IoT reference platform boots on an Arm CoreStone 700 FVP with a kernel binary reduced to kernel XIP 1.8MB and a target device spec of 4MB RAM / 8MB XIP flash. Build uses Yocto Poky Tiny producing a full image and uses CramFS XIP rootfs for zero-RAM code execution; writable storage is a littleFS port halfway into Linux (power-loss resilient, wear-leveling). OpenAMP handles A‑to‑M messaging; plans include upstreaming littleFS and size cuts via clang LTO/outline.
