Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:19 reviews, 20 commits, 38 PRs in 3 years 7 months
Contributions summary:Daniel primarily contributed to the Zephyr SDK, focusing on toolchain and build system enhancements for the Xtensa architecture. They addressed issues with MIPS toolchain inclusion, expanded support for the x86_64 toolchain, and added configurations for Xtensa-based SoCs, including Intel Apollo Lake and S1000. Further, they enabled essential functions like `remainderf` and `sqrtf` within the newlib library for Xtensa, ensuring proper functionality on the target architecture.
