[dss-developer] Improved firmware update process

[Troß, Michael]

Hi,

I'm glad to announce that the DSS firmware _u_pdate process has been
greatly improved. This new process will get active soon, production
release is planned in the next weeks. The highlights are:

- secured the update image with signatures to ensure integrity and
authenticity
- changed from package files to a single versioned image file
- the update data for DSS Addons is included in the image file to
simplify the upgrade, e.g. the second update step is no longer necessary
- the upgrade dialogue informs about new version number of new image
file instead of long list of package data

The upgrade is performed by erasing and reprogramming the flash-memory,
the user settings written via Configurator are retained, but all
"manual" changes to the file system will get lost. If you e.g. uploaded
data to the "dssadmin" home directory or applied other changes directly
to the filesystem they will not be restored. If this is an issue for
your systems or your customers please take care to preserve the data
before updating. The new update process will be available for the
hardware models DSS11-1GB, DSS11E, DSSIP, DSS20.

Best regards,
Michael
