System and method for updating and distributing information

A method of operating an electronic client device having a non-volatile memory, the non-volatile memory comprising a change indicator for signaling the availability of an update package received via a communication medium, the method comprising:

• detecting a state of the change indicator Indicating the availability of the received update package;
• performing a fault tolerant update of non-volatile memory if the change indicator is set;
• refraining from performing a fault tolerant update of non-volatile memory if the change indicator is not set;
• and
• resetting the change indicator upon completion of the fault tolerant update.

A method of operating an update server, the update server communicatively coupled to an electronic client device containing a code, the update server having stored upon it at least one update package, the method comprising:

• receiving at least one identifying characteristic from the electronic client device;
• selecting one of the at least one updated package based on at least one identifying characteristic, the selected update package comprising a set of instructions for converting the code into an updated code;
• and
• communicating to the electronic client device the selected pudate package comprising a set of instructions for converting the code into an updated code.

A method of operating an electronic device having a non-volatile memory, the non-volatile memory comprising a plurality of banks, the method comprising:

• (a) selecting one of the plurality of banks;
• (b) determining whether or not the selected bank has been updated;
• (c) updating the selected bank if it is determined that it has not been updated;
• (d) refraining from updating the selected bank if it is determined that it has been updated;
• (e) repeating (a) through (d) until it is determined that all of the plurality of banks have been updated;
• and
• wherein the determining compares a first value to a second value, the second value being calculated from a contents of the selected bank.

A method of operating an update distribution system for delivering to an electronic device an update package, the electronic device having at least one identifying characteristic, the method comprising:

• provisioning the update package using the at least one identifying characteristic, the update package comprising a set of instructions for converting a first code version to a second code version;
• retrieving using at least one retrieval criterion the update package comprising the set of instructions for converting a first code version to a second code version;
• and
• providing to the electronic device the retrieved update package comprising the set of instructions for converting a first code version to a second code version.
