Embedded bootloaders: MCU, Linux and FPGA approaches compared

Short summary

Bootloaders are critical to device reliability across embedded platforms. MCU, Linux, and FPGA systems require different approaches, but all need image validation, rollback capability, and power-loss testing. Treat bootloader design as product reliability architecture, not an afterthought.

• •Bootloader design is critical for device reliability and OTA updates across MCU, Linux, and FPGA platforms
• •Professional bootloaders require image validation, version policy, rollback capability, and failure diagnostics
• •Power-loss testing and metadata protection are essential to prevent field failures during updates
