Abstract
A method (100) is provided for initializing a processing system. The method (100) includes a plurality of steps. Those steps are: loading a primary code block in a flash memory (104); loading an alternate code block in a secondary storage (106); testing the primary code block upon power up of the processing system (134); loading the primary code block from the flash memory into a shadow RAM if the primary code block is not defective (140); and loading the alternate code block from the secondary storage into the shadow RAM if the primary code block is defective (139).
