7.8.2 Program Software Image into Memory

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.
CAUTION
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 PTP 500 Series bridge boot code
will boot the fixed software image. If this occurs the user must attempt to reload the
correct version of software.
During the write process the progress of the upgrade is displayed on the progress tracking
page (Figure 68). The upgrade process should not be interrupted. Interruption of this process
can result in a corrupt main software image, which will result in the recovery image been
booted at the next reset cycle.

7.8.3 Software Upgrade Complete

When the software image has been written to non-volatile memory, Figure 69 is displayed
showing the status of the software upload.
