Abstract:
An electronic device includes an input/output (I/O) interface and a plurality of memory elements comprising a non-volatile memory portion for storing a default firmware and a working memory portion having a firmware area. The device also includes a controller coupled to the I/O interface and the memory elements, where the controller is configured for operating the memory elements, according to the firmware area, and for monitoring the I/O interface. In the device, the controller is also configured for loading the default firmware into the firmware area when the controller is enabled and for granting access to the firmware area for loading an alternate firmware if a bypass code is detected at the I/O interface.
