About this task
It takes the following steps:
- Perform a signature check of the manifest file.
- Open the manifest file to lookup for the filename of the image and its relative path.
- All images and signature files are first downloaded
and saved to temporary files in the embedded Slot1 compact flash.
- After all the images are successfully downloaded,
the system will first perform a CRC check and then proceed to verify all the
signatures of each binary. If there's any failure, the upgrade is aborted and a
Syslog message is posted.
It will repeat the same steps for all images necessary for the upgrade.
If an image cannot be located, an error is logged and it will proceed to boot with application and monitor images synced from the MP.
