EMBEDDED SYSTEMS WITH ZIG: BARE METAL TO IOT: Build Safe and Efficient Firmware for ARM and RISC-V Microcontrollers. Real-Time Systems, Hardware Drivers, and IoT Applications

About This Product

Build production-grade embedded firmware that is safe, fast, and testable, from bare metal bring up to connected IoT systems. Modern firmware teams face strict reliability requirements, tight memory budgets, and evolving toolchains. Getting clocks, interrupts, and linkers right, then layering networking and security, takes a clear process, not guesswork. This book gives you that process. Using Zig as the build spine, it walks through Cortex-M and RISC-V bring up, robust drivers, real-time scheduling, low-energy design, secure networking, and field-ready updates. Each topic is grounded with code and hardware-level measurements. pin toolchains and produce reproducible builds with zig stage2, clean project layout, and c and assembly integration bring up cortex m correctly, vector tables, clock trees, flash wait states, systick time bases that do not drift stand up risc v machine mode, mtvec setup, clint timer ticks and alarms, plic priorities with proper claim and complete control image layout with lld, sections and regions, mcuboot integration, uf2 packaging, and map file size audits debug with openocd pyocd j link and black magic probe, log over itm and swo, measure latency with the dwt cycle counter run freertos and zephyr, set max syscall interrupt priority, configure devicetree and kconfig, use sysbuild with mcuboot build durable drivers, gpio with emi-safe debouncing, nonblocking uart spi i2c with ring buffers, timers and pwm, dma with cache coherency on cortex m7 design low power systems, select sleep states on arm and risc v, stm32u5 lpbam pipelines that run while the cpu sleeps, current residency math and wake budgets network with lwip raw api, mqtt over tls with keep alive and reconnect, coap with oscore, ble and ieee 802154 via zephyr secure and update devices, trustzone m and tf m services, risc v pmp isolation, ota using mcuboot and suit manifests, rollback and recovery simulate and test, qemu m profile and virt boards, renode multi node networks, hardware in the loop in ci, version pinning for zig sdks and probes apply patterns in capstones, stm32u5 secure sensor node with low power proof, rp2040 pio dma pipeline with deterministic timing, sifive e310 timer and plic clinic, end to end iot sample with transport selection and safe ota This is a code-heavy guide. Working Zig and C snippets show exact registers, linker directives, and build steps so you can replicate results on real boards and ship with confidence.
