WS1 — OTA and update delivery

Programme: https://github.com/DynamicDevices/mender-rt1180-zephyr/blob/main/mender-mcu-integration/PROJECT-NOTES.md#ws1--ota-and-update-delivery · Parent: #1

Milestones

ID	Milestone	Target	Status
M-003	Phase 1 hardware flash + DHCP (EVK or FRDM)	2026 Q3	Open
M-004	Phase 2 OTA + MCUboot swap on hardware	2026 Q3–Q4	Open

Definition of done

• M-003: Serial boot log; DHCP on NETC port; net iface shows IPv4 (evidence)
• M-004: Hosted Mender deployment finished; post-reboot new artifact_name (e.g. reboot to dev-2); MCUboot swap rollback validated

WS1 overall: Hardware-proven zephyr-image OTA on EVK and FRDM with MCUboot swap rollback; documented update SLO; Mender deployments used for security-patch delivery.

Dependencies

• Pre-hardware checklist complete (https://github.com/DynamicDevices/mender-rt1180-zephyr/blob/main/mender-mcu-integration/PROJECT-NOTES.md#pre-hardware-checklist)
• Phase 0 / 0b done (M-001, M-002)
• Lab network DHCP to Hosted Mender; group rt1180-lab
• See Zephyr testing plan Phases 1–2

Blocks

• M-005 (production signing) should follow or run in parallel before fleet
• WS3 security fix via Mender deploy ties to Phase 2 completion
