Abstract

A method includes receiving, by a microcontroller, a live firmware update (LFU) command from an external host; and downloading, by the microcontroller, an image of a new version of firmware responsive to the LFU command. During a first time period, the method includes initializing only variables contained in the new version that are not contained in an old version of firmware. During a second time period, the method includes updating one or more of an interrupt vector table, a function pointer, and/or a stack pointer responsive to the new version. The second time period begins responsive to completing initialization of the variables.
