发明名称 A method and system of locating a firmware image in non-volatile memory
摘要 <p>A method of locating a starting point of a firmware image in a non-volatile memory unit may include checking (151) each of a number of possible starting points within the non-volatile memory unit (101) until a code space signature (120) is located that indicates the starting point of the firmware image (100). A system for implementing this method in a host device (108) may include a non-volatile memory unit (101) of the host device (108), and a boot module (102) stored in the host device (108) for execution by a processor (107), where the boot module (102) is configured, when executed, to check (151) each of a number of possible starting points for the firmware image (100) within the non-volatile memory unit (101) until a code space signature (120) is located that indicates the starting point of the firmware image (100). A method of locating where in a non-volatile memory unit (101) an incoming firmware image (100b) can be stored may include, on receipt of a the incoming firmware image (100b), attempting (164) to erase at least one block (101a) of the non-volatile memory unit (101) and storing (166) the incoming firmware image (100b) in the non-volatile memory unit (101) where the attempt to erase succeeds. A system for implementing this method in a host device (108) may include a processor (107) of the host device (108) for running an existing firmware image (100a) and a non-volatile memory unit (101) of the host device (108), where the existing firmware image (100a) is configured, on receipt of a the incoming firmware image (100b), to attempt (164) erasure of at least one block (101a) of the non-volatile memory unit (101), and store the incoming firmware image (100b) in the non-volatile memory unit (101) where the attempted erasure succeeds. &lt;IMAGE&gt;</p>
