February 2025: Expanded kernel support for the AD916x family on the analogdevicesinc/linux repository by implementing Device Tree Source integration for AD9161 and AD9163 on ZCU102 platforms, and by fixing critical interpolation logic to ensure JESD204 functionality remains consistent with the AD9162 baseline. These changes improve hardware evaluation readiness and reduce integration risk for customers relying on Xilinx-based setups.

Jan 1, 2025

January 2025 monthly summary for analogdevicesinc/linux. Focused on delivering AD9162 DAC support for ZCU102 in MODE 8. Implemented a complete Device Tree Source (DTS) configuration and related hardware settings to enable MODE 8 operation on the AD9162 FMC evaluation board, including clocking, SPI, and JESD204 parameterization. No critical bugs were reported this month; all planned work completed on schedule. The work accelerates MODE 8 evaluation readiness, improves hardware integration, and strengthens our ARM64/Xilinx kernel capabilities. Technologies demonstrated include DTS authoring, Linux kernel configuration for peripheral interfaces (SPI, JESD204), clocking orchestration, and ARM64/Xilinx platform development.
