//*****************************************************************************
//
// Main entry point for the USB stick update example.
//
// This function will check to see if a flash update should be performed from
// the USB memory stick, or if the user application should just be run without
// any update.
//
// The following checks are made, any of which mean that an update should be
// performed:
// - the PC and SP for the user app do not appear to be valid
// - a memory location contains a certain value, meaning the user app wants
// to force an update
// - the user button on the eval board is being pressed, meaning the user wants
// to force an update even if there is a valid user app in memory
//
// If any of the above checks are true, then that means that an update should
// be attempted. The USB stick updater will then wait for a USB stick to be
// plugged in, and once it is look for a firmware update file.
//
// If none of the above checks are true, then the user application that is
// already in flash is run and no update is performed.
//
// \return None.
