May 2026 monthly summary focusing on key accomplishments, with cross-repo recovery optimization for nRF92 implemented in Zephyr and SDK Zephyr. The work delivers faster device recovery, reduced risk of partial MRAM recoveries, and alignment with Ironside SE’s full-erase flow. Upstream collaboration and cross-repo consistency improve maintainability and time-to-recovery for field devices.

Month 2025-11 highlights: Delivered IronSide SE compatibility integration for the nRF9280 in sdk-zephyr by merging the cpuapp iron variant into the base variant and deprecating legacy firmware. This aligns with security/compliance goals, reduces maintenance burden, and ensures consistent builds across hardware. Key actions included updating board configurations (nrf9280pdk), removing support for running samples/tests on obsolete firmware, and aligning with IronSide SE standards. The work was implemented via two commits, including a cherry-pick from the original patch branch.
