The guide covers: - Background on HS-FS and HS-SE device sub-types - The fuse_otp binary blob structure with a diagram illustrating the layout - Step-by-step key writer example flow - Post-programming note that eFuse changes require a full SoC power cycle to take effect Register the new page in the AM62LX Linux TOC and U-Boot Users Guide index.
