4. Upgrade using fixed multicast groups
In this variant the utility
mcast
(Linux) or
mcast.exe
(Windows) is used for organizing the
process of upgrading. This utility provides broadcasting of two multicast groups
simultaneously. The
Bootstrap
is broadcast in the first group at the address
224.50.0.50:9000
. The
imageupdate
prepared by the manufacturer or communication
operator is broadcast in the second group at the address
224.50.0.51:9001
. The «MC
Upgrade» function is started in the bootstrap loader menu, which initiates receiving
Bootstrap
from the group
224.50.0.50:9000
. After loading,
Bootstrap
in its turn receives the main
image of
imageupdate
from the address
224.50.0.51:9001
. After reception is completed
the image received is being checked for correctness. Providing everything is correct the
image is being written into the flash-memory of the device.
Thus, if Windows is used, the whole process is performed practically automatically. It is
enough to load the files
mcast.exe
,
Bootstrap
and
imageupdate
to the computer acting as the
server, activate mcast.exe utility and having selected the item of the bootstrap loader menu
«Upgrade Tools» > «MC Upgrade» initiate the automatic upgrade procedure on the device.
