Worked on the kholia/zephyr repository to enhance the iCE40 FPGA driver, focusing on improving configuration reliability and maintainability. Addressed hardware interaction challenges by adding build-time assertions in C to catch misconfigurations early and validating CDONE state after reset. Simplified the driver’s mode selection by replacing a complex enum with a boolean flag for SPI versus GPIO bitbang, and updated device-tree bindings in YAML to enforce safer defaults. These changes streamlined hardware bring-up, reduced the risk of deployment errors, and aligned device-tree and YAML bindings, ultimately strengthening the integration of iCE40 FPGA support within embedded Zephyr environments.

Nov 1, 2024November 2024 (kholia/zephyr): Focused on stabilizing the iCE40 FPGA driver, simplifying load-mode configuration, and tightening device-tree bindings. Delivered a robust configuration path for iCE40 with build-time assertions, improved CDONE handling, and corrected SPI waveform behavior. Implemented mode selection simplification by replacing a cumbersome enum with a boolean flag for SPI vs GPIO bitbang and updated device-tree bindings to reflect safe defaults. These changes reduce misconfiguration risk, speed hardware bring-up, and improve overall maintainability across the Zephyr iCE40 integration.
