摘要：
An electronic device is disclosed comprising a non-volatile memory storing a first version of a control program (CP), a first header comprising a first version identifier (VID) identifying the first version of the CP and a first VID check code generated in response to at least the first VID. The non-volatile memory further stores a second version of the CP, and a second header comprising a second VID identifying the second version of the CP and a second VID check code generated in response to at least the second VID. When the first and second VIDs are valid, the electronic device selects between the first version and the second version of the CP in response to the first and second VIDs, and executes the selected version of the CP.
