  • Method and apparatus of remotely updating firmware of a communication device
    Patent number: 6640334
    Abstract: A method and apparatus for remotely updating firmware saved in a FLASH memory of a communication device connected to a network is presented. The FLASH memory is partitioned into at least a first and a second portion. A first firmware load is stored in the first portion. During run-time of the first firmware load, at least a portion of an updated firmware load is transmitted through the network to the communication device. The transmitted portion of the updated firmware load is temporarily stored in a buffer of the communication device. At least a portion of the first firmware load is copied into a random access memory (RAM) of the communication device. Execution, from the RAM, of the copied portion of the first firmware load is triggered. Under control of the copied portion of the first firmware load, the transmitted portion of the updated firmware load is saved to the second portion of the FLASH memory.
