Embedded Linux platform engineering: from boot chain to production image
An embedded Linux product is not just a kernel image. A maintainable platform includes bootloader, board support, reproducible build, services, diagnostics and update behavior.
Start with the boot chain
Power, reset, clocks, storage and bootloader behavior must be deterministic before higher-level software can be trusted.
Make the BSP reproducible
Device tree, kernel configuration, patches and package selection belong in version-controlled build infrastructure, not in manual workstation steps.
Design field service early
Logging, watchdogs, recovery and update strategy affect both software architecture and the way the hardware is deployed.
Treat Linux as part of the product architecture
The right boundary between MCU firmware, Linux services and application software depends on timing, startup and reliability requirements.
