Apache Mynewt Bootloader for Reliable and Secure Firmware Upgrades
Talkat Embedded Linux Conference + OpenIoT Summit North America 2017 · on Wednesday, 2017-02-22· at 15:00· Galleria South·
summary
An open bootloader refactor (MCUboot) runs on Cortex‑M devices, compiles to about 12 KB bootloader code, and implements two image slots plus a scratch sector to do atomic swaps across power loss. Images use SHA‑256 plus RSA or ECC signatures verified at boot; unconfirmed boots roll back automatically. Builds include image_tool for signing and a simulator for tests; project already runs hundreds of thousands of upgrades on Mynewt and Zephyr platforms.
