The software image will now be uploaded to the unit. This upload should only take a few
seconds. Once complete the image is verified and validated to ensure that no errors occurred
during transfer and that the image is valid to run on the current platform. If there are any
problems a warning screen will appear.
The unit being upgraded will now display information about the build it currently has stored in
the image bank and the one that’s just been uploaded. If the image is not the right one, the
user has the option to go back and reload a new image. (See
1123HFigure 71)
Figure 71 - Software Upgrade Image Check
The user should ensure that the correct image is shown before pressing the “Program
Software Image into Non-Volatile Memory” button. Once this button has been pressed the
image is stored into non-volatile memory, this process can take up to 60 seconds and must
not be interrupted.
If the upgrade process is interrupted during the erasure of the image bank, or during the
reprogramming of the image bank, the image bank will be left in a corrupt state. If this occurs
the software must be reloaded. All software images that are stored in non-volatile memory are
protected via the use of CRCs. If the software detects an invalid CRC the image bank is
marked as ‘corrupt’ and the 600 Series bridge boot code will boot the fixed software image. If
this occurs the user must attempt to reload the correct version of software.
