Compact Linux Distro and NV MRAM Technology:
Bring performance to resource constrained system

Presented byLinaro Limited

Meeting automotive boot time requirements, such as the 2-second rearview camera mandate presents a challenge on ECUs, especially during recovery from failures. This talk approaches combines a highly optimized, Compact Linux with Spintronics MRAM technology to overcome the challenges. We demonstrate a complete, minimal-footprint system built with Yocto, featuring a tiny U-Boot (< 87 KiB) and a Linux kernel with rootfs 12 MiB MRAM partition. By leveraging MRAM's fast read speeds + SRAM-like interface, we implement XIP for the bootloader and kernel, achieving 100ms boot times to the U-Boot shell. This architecture elimitates external FLASH and DRAM, resulting in a startup time that is 30 times faster and an 1/50 power consumption compared to conventional systems, providing a robust solution for safety-critical automotive applications.* This presentation was obtained as a result of a project (JPNP23015) commissioned by NEDO (New Energy and Industrial Technology Development Organization).
