MCUboot Integration

Overview

Use this skill to integrate MCUboot by proving the boot chain, flash map, image format, signing flow, and upgrade policy. Most failures come from slot geometry, trailer layout, or signing metadata mismatches rather than the application itself.

When To Use

Use this skill when:

• The user wants to add MCUboot to Zephyr, Mynewt, NuttX, RIOT, Mbed OS, ESP-IDF, or a custom MCU platform.
• The issue involves image validation, swap, overwrite-only upgrade, rollback, confirm flags, serial recovery, or signed images.
• The project has dual slots, external flash, encrypted images, secure boot, or OTA requirements.

Do not use this skill for application-level firmware transfer alone. Use ota-update-integration first if the bootloader is already fixed and the issue is delivery. For generic bootloader jump/handoff debugging, use bootloader-debug.
