Firmware update in electronic devices employing update agent in a flash memory card

摘要

A controller in a removable memory card operatively coupled to an electronic device is employed by the electronic device to create a newer/updated version of firmware/software in the non-volatile memory of the electronic device. Update agent code in the removable memory card may use an old/original version of firmware/software in the electronic device to create the newer/updated version of firmware/software. During the creation of the newer/updated version of firmware/software in the flash memory card, the electronic device may be operational. A separate update agent in the electronic device may subsequently update the old/original version of firmware/software in the non-volatile memory of the electronic device using contents of the removable memory card, after a reboot or power-up of the electronic device.
