    Renode with Michael Gielda

    Michael Gielda, co-founder and VP of Business Development at Antmicro, discusses Renode, an open-source simulator for embedded systems that allows developers to run production binaries on a computer. He explains how Renode’s determinism and multi-node capabilities enable repeatable continuous integration testing, serving as a drop-in replacement for physical hardware rigs in many scenarios. Gielda details the tool's support for various architectures like ARM Cortex-M and RISC-V, its integration with the Zephyr OS via device trees, and the company's strategy of building commercial simulation models for clients while maintaining an open-source core.

    433: Getting Mad About Capes

    Michael Gielda, co-founder of Antmicro, explains Renode, an open-source simulator for embedded systems and distributed networks that allows developers to test software on virtual hardware without physical boards. He details how Renode models peripherals and supports multi-node simulations to catch 90% of bugs early, while discussing the company's deep involvement in the RISC-V ecosystem and the challenges of open-source hardware fragmentation. The conversation also covers the practicalities of using Renode in education and CI/CD pipelines, as well as the current state of Rust adoption in embedded development.

    274: Swiss Knife of Embedded Systems

    Ivan Kravets, founder of PlatformIO, explains how his open-source toolchain simplifies embedded development by providing a unified build system, library registry, and debugger that works across multiple IDEs and operating systems. He discusses the platform's architecture, which allows developers to switch between frameworks like Arduino and mbed with minimal configuration changes, and highlights the benefits of its unified debugging engine. Kravets also shares insights from the RISC-V Summit, noting Western Digital's adoption of RISC-V for custom controllers and the growing commercial viability of open-source processor architectures.

    044 - Scots Army Knife

    Piotr Esden-Tempski of 1BitSquared discusses the company's role in manufacturing open-source hardware, specifically the Glasgow digital interface explorer, the iCEBreaker FPGA board, and the Black Magic Probe debugger. He explains the economic rationale for using an old Quad 4C pick-and-place machine for small-batch production and details how Glasgow uses an FPGA to dynamically generate hardware protocols via the nmigen HDL. The conversation also covers the geopolitical shift toward RISC-V in China, the challenges of debugging legacy industrial equipment, and the importance of documentation and community education in the open-source hardware ecosystem.
