During five months on the tenstorrent/tt-zephyr-platforms repository, Bli developed and maintained embedded firmware for high-speed Ethernet hardware, focusing on ERISC firmware upgrades and robust device integration. Bli engineered features such as enhanced Ethernet training, mailbox-based link monitoring, and dynamic configuration for ASICs, using C, DTS, and Zephyr RTOS. The work included resolving system hangs, improving telemetry accuracy, and expanding firmware partitioning to support larger images. Through disciplined release management, detailed documentation, and close hardware-software alignment, Bli delivered stable, traceable updates that improved reliability, performance, and observability for complex networking workloads across multiple board configurations and release cycles.

Mar 1, 2025Month: 2025-03 — Summary for tenstorrent/tt-zephyr-platforms. This period focused on delivering a critical firmware upgrade and ETH training optimization that materially improves reliability and throughput for high-speed networking workloads. Key features delivered: - ERISC firmware upgraded to v1.2.0 with SerDes ETH FW 0.9.16. This update enhances ETH training stability and performance, and lays groundwork for future optimizations. - ETH training optimization implemented to reduce training variability and improve connection readiness under load. - Default ETH training speed increased to 400 Gbps, enabling higher throughput for supported configurations. Major bugs fixed: - Resolved a potential system hang during ETH training, significantly improving reliability in edge cases and during rapid ramp scenarios. Overall impact and accomplishments: - Improved platform reliability and predictability for high-speed ETH links, reducing risk of outages and service interruptions. - Faster time-to-deploy for network workloads thanks to faster training readiness and a more stable firmware baseline. - Strengthened hardware-software integration through firmware versioning, release discipline, and cross-team collaboration with the ERISC/ETH subsystems. Technologies/skills demonstrated: - Embedded firmware development and release management (Zephyr RTOS, ERISC/esoteric SerDes integration). - Firmware versioning, build/test pipelines, and traceability from commit to vulnerability-free release. - Performance tuning and reliability engineering for high-speed networking hardware.
