Abstract

The invention provides a system and a method of selecting a version of a program code from a series of program codes for a program element associated with a hardware element for a circuit board. The invention identifies a compatible program code for a particular hardware element and downloads the compatible program code. A record is associated with the hardware element to identify its compatible program codes. The program codes are stored in a bundle and are associated with a software code. A program loader, associated with each bundle, checks the compatibilities of the hardware element to both the software code and the selected program code. Another record stores compatibility information of the program codes with hardware element versions and is also associated with the bundle. Code downloads are made first to an inactive memory bank and after the codes are verified, the inactive memory bank is made active.

Claims

1. A method for updating software and firmware operating with hardware located in a main controller device and at least one associated module device in communication therewith, said method comprising:

receiving at the main controller device an updated application bundle, the updated application bundle having an updated software element, a set of firmware elements relating to the updated software element, and a firmware loader for loading the firmware elements relating to the updated software element;

determining whether the updated application bundle is operable with a hardware element of the main controller device and the at least one associated module device;

installing the updated application bundle in the main controller device and the at least one associated module device if the updated application bundle can be operated with the hardware element; and

,

utilizing an existing application bundle at the main controller device and the at least one associated module device if the updated application bundle cannot be operated with the hardware element;

wherein the determining whether the updated application bundle is operable with the hardware element includes;

storing a hardware/software compatibility level value and a hardware/firmware compatibility level value on the main controller device and the at least one associated module device;

retrieving the hardware/software compatibility level value and the hardware/firmware compatibility level value with the firmware loader; and

,

searching a matrix with the firmware loader using the hardware/software compatibility level value and the hardware/firmware compatibility level value to determine whether a version of the software element and a version of the firmware elements provided in the updated application bundle are compatible with the hardware element, the matrix listing versions of the software elements compatible with the hardware element for the hardware/software compatibility level value and versions of the firmware elements compatible with the hardware element for the hardware/firmware compatibility level value.

2. The method of claim 1, wherein:

the main controller device controls the at least one associated module device;

the installing of the updated application bundle in the main controller device is performed remotely; and

,

the installing of the updated application bundle in the at least one associated module is performed by the main controller device.

3. The method of claim 1, wherein the matrix is stored remotely from the main controller device and the at least one associated module device.

4. The method of claim 3, wherein the matrix is accessible by the main controller device.

5. The method of claim 1, wherein the existing application bundle includes an existing software element, a set of firmware elements relating to the existing software element, and a firmware loader for loading the firmware elements relating to the existing software element.

6. The method of claim 1, wherein the updated application bundle and the existing application bundle are stored in the main controller device.

7. The method of claim 1, wherein:

the receiving at the main controller device of updated application bundle includes storing the updated application bundle in a memory bank at the main controller device having an inactive status; and

,

the existing application bundle for the main controller device is stored in a memory bank at the main controller device having an active status.

8. The method of claim 7, wherein the installing of the updated application bundle includes:

exchanging the inactive status of the memory bank storing the updated application bundle for the active status of the memory bank storing the existing application bundle;

downloading to the at least one associated module device the updated application bundle from the memory bank storing the updated application bundle; and

,

utilizing the updated application bundle instead of the existing application bundle for the main controller device and the at least one module device.

9. The method of claim 1, wherein the updated application is received from a library of application bundles stored external to the main controller device and the at least one associated module device.

10. The method of claim 1, wherein the main controller device and the at least one associated module device are located on a circuit card of a communication switch.

11. The method of claim 1, wherein the main controller device and the at least one associated module device are located on respective circuit cards in a communication switch.

12. A system for updating software and firmware operating with hardware located in a main controller device and at least one associated device connected thereto, said system comprising:

a processor coupled to memory and a communication device at the main controller device and at the at least one associated device; and

,

modules within the memory and executed by the processor, the modules including;

a module for receiving at the main controller device an updated application bundle, the updated application bundle having an updated software element, a set of firmware elements relating to the updated software element, and a firmware loader for loading the firmware elements relating to the updated software element;

a module for determining whether the updated application bundle is operable with a hardware element of the main controller device and the at least one associated device;

a module for installing the updated application bundle in the main controller device and the at least one associated device if the updated application bundle can be operated with the hardware element; and

,

a module for utilizing an existing application bundle at the main controller device and the at least one associated device if the updated application bundle cannot be operated with the hardware element;

wherein the module for determining whether the updated application bundle is operable with the hardware element includes;

a module for storing a hardware/software compatibility level value and a hardware/firmware compatibility level value on the main controller device and the at least one associated device;

a module for retrieving the hardware/software compatibility level value and the hardware/firmware compatibility level value with the firmware loader; and

,

a module for searching a matrix with the firmware loader using the hardware/software compatibility level value and the hardware/firmware compatibility level value to determine whether a version of the software element and a version of the firmware elements provided in the updated application bundle are compatible with the hardware element, the matrix listing versions of the software elements compatible with the hardware element for the hardware/software compatibility level value and versions of the firmware elements compatible with the hardware element for the hardware/firmware compatibility level value.

13. The system of claim 12, wherein:

the module for receiving at the main controller device the updated application bundle includes a module for storing the undated application bundle in a memory bank at the main controller device having an inactive status; and

,

the modules further include a module for storing the existing application bundle in a memory bank at the main controller device having an active status.

14. The system of claim 12, wherein:
