March 2026: Delivered a TMCM-3216 Stepper Motor Controller Demo sample in nxp-upstream/zephyr to validate and demonstrate end-to-end stepper control capabilities. This provides a repeatable reference for customers to evaluate TMCM-3216 and accelerates integration with the Zephyr ecosystem. No major bugs reported or fixed this month, with emphasis on feature delivery, test coverage, and code quality.

February 2026: Delivered end-to-end TMCM-3216 RS485 support in nxp-upstream/zephyr, including device-tree bindings and a dedicated Zephyr driver for up to 3 motors. Implemented robust TMCL transport with 9-byte datagrams, checksum validation, half-duplex handling, and DE pin control; added semaphore-protected bus access. Exposed public API (tmcm3216_set_max_velocity/get_max_velocity, set_max_acceleration, get_actual_velocity, get_status) and built comprehensive build-time options (Kconfig) with automatic RS485 bus selection when TMCM-3216 is enabled.

October 2025 (linux-riscv/linux) — Focused on power management driver maintenance to ensure firmware compatibility and measurement accuracy. Delivered a targeted coefficient update for the ADPM12160 power module in the max34440 hwmon driver to align with the latest firmware, ensuring accurate readings and reporting from the device. This fix addresses drift introduced by the firmware update and improves overall system visibility into power usage. The change was implemented as a single, clearly documented commit for traceability (hwmon: (pmbus/max34440) Update adpm12160 coeff due to latest FW).

April 2025 performance highlights across two repositories (analogdevicesinc/linux and analogdevicesinc/hdl): strengthened hardware monitoring and PMIC integration, expanded device support, and improved documentation. Deliverables focus on improved protection accuracy, broader device coverage, and clearer developer guidance, enabling faster hardware integration and reduced risk.

March 2025 monthly summary for analogdevicesinc/hdl: Delivered comprehensive documentation updates to support developer onboarding and integration with ADI components. Focus areas included the DC2677A demonstration circuit, AXI LTC235x IP core, obsolete AD-FMCLIDAR1-EBZ project, AD4170/AD4190 support, and AD353XR devices. There were no code defect fixes this month; the work enhances maintainability and reduces time-to-value for customers and internal teams.

December 2024: Delivered two high-impact features that advance hardware bring-up, configurability, and cross-board support, with clear business value for customers and faster time-to-market. Key features delivered: - ADP5055 regulator support added to the Linux kernel configuration (Kconfig.adi). This ensures REGULATOR_ADP5055 is implied when KERNEL_ALL_ADI_DRIVERS is selected and enables configuration and use of the ADP5055 PMIC within the kernel. Commit: ea9ff1f4bb2e409f2f069200f91d59dc3a42c1a3. - AD353XR HDL driver multi-board integration: initial HDL driver project including documentation and multi-board setup with build files, constraints, and top-level modules for coraz7s, zedboard, and de10nano. Commits: f4f0c866e8055163aedb9c184ca11c4098fdd03f, 76b8ce5781fafd28d99dd5d2fefebddd5f79aafa, 5a07d8fff61a5a2af9d46a89141072870e4d7574, 3cfeca45b27ec5f979c9d1d963eb23987f005fec. Major bugs fixed: - No major bugs fixed this month according to the provided data. Overall impact and accomplishments: - Enabled reliable hardware bring-up for the ADP5055 PMIC in Linux, improving kernel configurability and device support for end users. - Established a cross-board HDL driver framework for the AD353XR, accelerating future feature work and testing across coraz7s, zedboard, and de10nano. This foundation supports faster validation, reduced integration risk, and clearer documentation for customers and internal teams. Technologies/skills demonstrated: - Linux kernel configuration (Kconfig.adi), PMIC integration, and kernel build considerations. - HDL driver development workflow, multi-board integration, hardware constraints, and top-level module organization. - Documentation and project scaffolding across multiple platforms to enable rapid adoption and testing.
