Files related to file authentication and device
configuration settings can be included in a
partial OS download.
Following a partial OS download, the device
does not restart and returns control to system
mode or the issuing application. The file
authentication module is not invoked, and the
new OS is not processed until you manually
restart the device from within system mode. If
the new OS is authenticated, it updates
(replaces) the existing OS.
Application files stored in the memory area
where the OS downloads into (Group 1) are
retained.
Here are a few more points on the topic of full and partial downloads:
•
The most common download procedure is a full (complete) application
download.
•
Partial application downloads are useful when developing and testing new
applications, but are seldom performed by those who deploy devices on-site.
•
Full OS downloads are usually performed by VeriFone at the factory and, on
occasion, by those who deploy devices on-site to upgrade older devices to a
newer OS version.
