Secure provisioning is a foundational step in productizing embedded Linux systems, especially when enabling secure boot and establishing silicon identity through eFuses or one-time programmable (OTP) memory. Yet many teams still rely on manual fuse programming flows that are error-prone and difficult to scale particularly when dealing with complex, vendor-specific fuse maps. This talk explores how modern U-Boot capabilities streamline secure device provisioning in real manufacturing workflows. It introduces an upstream enhancement to U-Boot’s fuse subsystem that supports bulk, structured eFuse programming. This approach makes fuse provisioning more automation-friendly, and suitable for production use. Attendees will gain practical insights on integrating U-Boot-based provisioning into factory flows.
Agenda:
1. Challenges in Traditional eFuse Programming on Embedded Systems
2. U-Boot’s Existing Fuse Subsystem and Its Limitations in Production Flows
3. Design and Upstream Integration of the 'fuse writebuff' command
4. Structured, Automated Provisioning using Memory Buffers
5. Practical Provisioning and Production Workflow Considerations
