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.
Use this skill when:
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.
Ask for:
Freeze the flash map. Slot sizes, erase block size, alignment, scratch size, and trailer offsets must match the target flash.
Build a minimal signed image. Verify image header, TLVs, signature, version, and load address before enabling OTA.
Prove first boot. Boot one known-good image from the primary slot and record bootloader logs.
Prove upgrade behavior. Test pending, test, confirm, revert, and permanent upgrade paths for the selected mode.
Add recovery and brick protection. Keep serial recovery, debug access, watchdog policy, and factory image strategy clear.
Lock security policy last. Enable key protection, rollback counters, encryption, or anti-tamper only after the basic upgrade loop is repeatable.

Use when debugging Cortex-R5 or Cortex-R firmware — TCM, MPU, caches, DFSR/DFAR aborts, exceptions, GIC/VIC interrupts, lockstep or split mode, ECC, or JTAG bring-up
Use when integrating or debugging heatshrink embedded compression — encoder/decoder sink/poll/finish loops, window/lookahead sz2, HSER/HSDR codes, or static vs dynamic alloc
Use when integrating, porting, or debugging micro-ecc (uECC) ECDH, ECDSA, key generation, uECC_set_rng, signatures, curve selection, or key/signature byte formats on an MCU
Use when debugging OpenOCD, J-Link, ST-Link, CMSIS-DAP, probe connection, reset scripts, flash algorithms, GDB attach, semihosting, RTT, or SWD/JTAG failures
Use when integrating, refactoring, or debugging PLOOC object-oriented C - def_class encapsulation, private_member protection, vtable dispatch, or inheritance-style structs
Use when integrating or debugging Li-ion charger/fuel gauge ICs (BQ24295, BQ27441, MAX17048) over I2C, covering charge start, watchdog host mode, NTC/JEITA faults, and SOC jumps
