instructions for execution by a computer system, wherein the instructions, when executed by the computer system, cause the computer system to implement a method comprising:determining whether an updating operation is to be performed;determining memory addresses of the memory medium at which a corresponding replacement image can be recorded;erasing the determined memory addresses; andwriting the corresponding replacement image to the determined memory addresses of the memory medium,wherein the one or more binary images comprise:
at least one kernel image,at least one file-system image,a boot-loader image, anda scratch area image,wherein the boot-loader image and the update logic image are recorded at different ends of a first predetermined portion of the memory medium at the start of the memory medium, wherein the scratch area image is recorded directly following the predetermined portion of the memory medium, and wherein the kernel image and the file system image are recorded at different ends of a second predetermined portion of the memory medium, following the scratch area image. |
