Firmware development
RTOS development: FreeRTOS and Zephyr
Real-time operating systems for devices that need more structure than a super-loop, but not a full Linux.
· by BCF Embedded engineering team
Scope
RTOS selection
Comparing FreeRTOS, Zephyr and other options against your requirements and ecosystem.
Migration
Moving from bare-metal to an RTOS without losing proven behaviour - see legacy modernization.
Memory and energy
Task design, stack sizing and low-power modes measured on hardware.
FreeRTOS or Zephyr?
FreeRTOS is small and widely supported by silicon vendors. Zephyr brings a device model, drivers and networking in one ecosystem. The right choice depends on your MCU, connectivity and the team that will maintain the code.
