Month 2025-08 — mcuboot CI: Centralized test container management by migrating to GHCR-hosted fih-test container, with a new configuration script and updated install/run scripts to pull images from ghcr.io/mcu-tools. This standardizes container usage across CI, improves reproducibility, reduces setup complexity for contributors, and lays groundwork for potential CI performance gains.

June 2025: Delivered a PSA Crypto build compatibility fix for MCUBOOT to prevent build errors when using the TF-PSA-Crypto backend. Implemented conditional inclusion of crypto/common.h in ecdsa.h only when MCUBOOT_USE_PSA_CRYPTO is not defined. The patch is isolated, well-documented, and aligns MCUBOOT with PSA cryptography integration, reducing downstream build failures and enabling smoother adoption of PSA crypto stacks.

March 2025 monthly summary for zephyrproject-rtos/trusted-firmware-m: Focused on reliability improvements in the TF-M RPC path, stability of the test suite, and security hardening through cryptographic library upgrades. Delivered concrete fixes and upgrade work that reduce risk and improve maintainability.

February 2025 monthly summary for zephyrproject-rtos/trusted-firmware-m. Key features delivered include TF-M Test Suite Version Synchronization and Initial Attestation Service simplification with t_cose alignment. No major bugs fixed this month. Overall impact: improved testing fidelity, reduced maintenance burden, and better upgradeability by aligning dependencies with upstream tf-m-tests and the t_cose library. Technologies demonstrated: build automation for dependency bumps, code simplification, documentation updates, and upstream integration. Business value: more reliable CI/testing, smoother upgrades, and reduced configuration drift across the TF-M project.

January 2025 monthly summary for zephyrproject-rtos/trusted-firmware-m: Completed maintenance work to improve build stability and test reliability in the PSA Crypto adaptor and test environment. Implemented code cleanup and test optimizations across COSE/PSA Crypto paths and BL2 bootloader to reduce dead code and flaky tests. Major commits focused on removing unused HKDF function, disabling irrelevant encrypt/decrypt tests, increasing secure test partition stack for t_cose tests, and removing deprecated flash_area_read_is_empty() from BL2. These changes reduce runtime risk, streamline CI, and improve overall product quality.

Month: 2024-11 | Focus: zephyrproject-rtos/trusted-firmware-m. This month centers on delivering a targeted size and performance optimization through COSE EDDSA removal in the signing/verification modules, with no reported major bugs fixed in scope of the provided data. The work aligns with goals for lean cryptographic code, faster builds, and better LTO outcomes.
