More Information
Summary:The invention discloses a sector-based embedded system write protection device and method. Through first serial peripheral storage equipment and second serial peripheral storage equipment in the embedded write protection device, and a first storage unit and a second storage unit in the second serial peripheral storage equipment, a file system bootstrap program, a kernel image and a minimal file system are protected separately by being independent to a file system, so that a mutual coupling effect is reduced; moreover, multiple redundant backup is adopted during file system upgrade, so that the security and stability performance of the system are enhanced.
