### Pre-Filled Template & Production Source

# Embedded Firmware taste of a reliability-minded firmware engineer
- Keep hardware access behind a thin hardware abstraction layer so application logic can be built and unit-tested on the host machine. Confidence: 0.90
- Run unit tests on the host in CI with Unity or GoogleTest, and keep on-target tests for drivers and timing only. Confidence: 0.85
- Avoid dynamic memory allocation after startup; allocate buffers statically or from fixed-size pools sized at compile time. Confidence: 0.90
- Use a small RTOS such as Zephyr or FreeRTOS once there are more than two independent timing concerns, instead of growing a hand-written super loop. Confidence: 0.75
- Keep interrupt handlers short: capture the data, set a flag or push to a queue, and do the real work in a task. Confidence: 0.95
- Mark data shared with interrupts as volatile and guard multi-byte access with critical sections or atomics. Confidence: 0.90
- Enable the hardware watchdog in production builds and feed it only from a health check that confirms every critical task is alive. Confidence: 0.90
- Build with -Wall -Wextra -Werror and run a static analyzer such as cppcheck or clang-tidy on every pull request. Confidence: 0.85
- Pin the exact cross-compiler version in a container image or toolchain file so every build is reproducible. Confidence: 0.90
- Use fixed-width integer types like uint32_t everywhere hardware registers, protocols or storage formats are involved. Confidence: 0.90
- Track flash and RAM usage per build in CI and fail when either crosses an agreed budget. Confidence: 0.80
- Ship over-the-air updates with an A/B partition scheme, signed images and automatic rollback if the new image fails to boot. Confidence: 0.90
- Verify firmware signatures in the bootloader with a key the application cannot overwrite. Confidence: 0.85
- Lock debug ports such as JTAG and SWD on production units, with a documented process for authorized recovery. Confidence: 0.80
- Store a crash record with the program counter, fault registers and reset reason in retained RAM and report it on the next boot. Confidence: 0.85
- Use structured, compact logging with log levels and a ring buffer, and avoid printf in interrupt context. Confidence: 0.80
- Write wear-aware storage code: batch writes, use a flash file system like littlefs, and never rewrite the same sector in a tight loop. Confidence: 0.85
- Version configuration stored in flash and migrate it on boot, rather than assuming the layout never changes. Confidence: 0.80
- Design for low power from the start: sleep by default, wake on interrupts, and measure current draw with real hardware. Confidence: 0.75
- Run a hardware-in-the-loop test rig in CI for the main boards before releasing a firmware version. Confidence: 0.70
- Embed the git commit hash and build time in every image and expose them through a version command or register. Confidence: 0.85
