Abstract

A method of in-place updating an original version of content to an updated version of content, in a non-volatile memory storage device, wherein the storage device comprises a non-paged part of the content, wherein the non-paged memory part includes an original update library, and wherein the storage device is being used in a normal mode of operation or in an update mode of operation, the method includes: obtaining an update package required for updating the original version of content to the updated version of content; obtaining a new update library; storing the new update library in a second non-volatile storage; and updating the original version of content to the updated version of content, in a non-volatile memory storage device, using the at least new update library and the update package.

Claims

1. A method of in-place updating an original version of content to an updated version of content, in a non-volatile memory storage device, wherein the storage device comprises a non-paged part of content, wherein the non-paged part comprises an original update library, and wherein the storage device is being used in a normal mode of operation or in an update mode of operation, the method comprising:

obtaining an update package required for updating the original version of content to the updated version of content;

obtaining a new update library;

storing the new update library on a second non-volatile storage; and

updating the original version of content to the updated version of content, in a non-volatile memory storage device, using the new update library and the update package.

2. The method of claim 1, wherein obtaining the new update library comprises extracting the new update library from the update package.

3. The method of claim 1, wherein obtaining a new update library comprises:

deriving from the update package, a part required for at least updating the original update library to the new update library;

storing the part of the update package on a third non-volatile storage; and

generating the new update library using the original update library from the non-paged part and the part of the update package from the third non-volatile storage.

4. The method according to claim 1, wherein the updating comprises:

in update mode, providing in a volatile memory associated with the device, an updated version of the non-paged memory part.

5. The method according to claim 1, wherein the updating further comprises invoking the updated version of the non-paged part in the volatile memory.

6. The method according to claim 4, wherein the providing of an updated version of the non-paged content further comprises:

invoking the new update library; and

generating in the volatile memory an updated version of the non-paged content using the original non-paged content in the non-volatile memory and the update package wherein the generating is such that the updated version of the non-paged part does not override the new update library on the volatile memory.

7. The method of claim 4, wherein the providing of the updated version of the non-paged memory further comprises:

loading into the volatile memory an updated version of part of the non-paged content and invoking said part, wherein said invoked part constructs in volatile memory or loads into volatile memory an updated version of said non-paged content.

8. The method of claim 4, wherein said providing of an updated version of the non-paged content further comprises:

loading into the volatile memory an updated version of the non-paged content.

9. The method of claim 4, wherein the providing of the updated version of the non-paged content further comprises:

loading into the volatile memory an updated version of part of said non-paged content and invoking said part, wherein said invoked part constructs in the volatile memory or loads into the volatile memory an updated version of the non-paged content excluding said part.

10. A system for updating an original version of content to an updated version of content, in a non-volatile memory storage device that enables a normal mode and an update mode, the system comprising:

a non-paged memory part on a non-volatile memory, wherein the non-paged memory part comprises an update library and an update agent; and

a boot loader,

wherein the update agent is arranged to;

obtain an update package comprising a update file that comprises commands and data required for updating an original version of content to an updated version of content;

derive, from the update file, a library file comprising commands and data required for at least updating the update library on the non-paged memory part of content;

store the library file on a non-volatile memory;

wherein the boot loader is arranged to;

obtain a new update library to the volatile memory; and

store the new update library on the non-volatile backup buffer.

11. The system according to claim 10, wherein the update agent and the boot loader are arranged, in cooperation, to update the original version of content to the updated version of content, in the non-volatile memory storage device, using the new update library, stored on the non-volatile memory.

12. The system according to claim 10, wherein the update agent obtains the new update library by extracting the new update library from the update package.

13. The system according to claim 10, wherein in obtaining a new update library, the update agent is further arranged to:

derive from the update package, a part required for at least updating the original update library to the new update library;

store the part of the update package in a third non-volatile storage; and

generate the new update library using the original update library from the non-paged memory part of content and the part of the update package from the third non-volatile storage.

14. The system according to claim 11, wherein in updating, the update agent and the boot loader are arranged, in cooperation, to provide in a volatile memory associated with the device, an updated version of the non-paged part.

15. The system according to claim 14, wherein the update agent and the boot loader are further arranged, in cooperation, to:

invoke the new update library;

generate in the volatile memory an updated version of the non-paged content using the original non-paged content in the non-volatile memory and the update package wherein the generating is such that the updated version of the non-paged part does not override the new update library on the volatile memory.
