In March 2026, Josef Emova addressed a compatibility issue in the nxp-upstream/zephyr repository by implementing a targeted fix for SPI anomaly 58 in the SPI driver for nRF52 chips. Using C programming and embedded systems expertise, Josef restored the anomaly-58 workaround to align with nrfx SDK 4.0.0, adding initialization glue between Zephyr and nrfx. The solution was carefully scoped to a single GPIOTE instance, minimizing risk and maintenance overhead for future SDK updates. Josef validated the change through builds and basic SPI flow testing, ensuring no regressions and maintaining stable driver behavior on affected hardware platforms.
