Upgrade of the device software
Variants of the device basic software upgrade
There are several variants of upgrading the basic software:
1. upgrade using cyclic multicast groups;
2. upgrade using the nfs-image of the root file system;
3. upgrade from the USB-storage;
4. upgrade using fixed multicast groups
The fourth variant is the simplest of all above-mentioned variants. It is described in detail
further in the text.
The first three variants are shortly described as to their realization and specifics. More
detailed information and description of utilities used in these variants can be found at the
address

.
1. Upgrade using cyclic multicast groups
This variant provides software upgrade for a large number of devices simultaneously.
The server side is configured for broadcasting two multicast groups, the first of which
broadcasts Bootstrap, and the second – the image prepared by the manufacturer or
communication operator. DHCP server is configured in such manner that it can recognize
different stages of the device loading by various
vendor-class-identifier
and return
the data required for the process of software upgrade at each stage of loading.
The device is transferred to the mode of loading from «DHCP». This can be achieved either
from the bootstrap loader menu or on the command of communication operator including via
JavaScript API.
Then the device will load and start Bootstrap, which receives the image of the basic software
and saves it in the flash-memory of the device. After flashing (writing data to flash-memory) is
completed the device is restarted in the mode of loading from «NAND».
2. Upgrade from USB-storage
This upgrading method is quite simple but it cannot be used if there is a probability that the
basic software does not function correctly.
The directory containing necessary utilities and images is created in the USB-storage. The
USB-storage is connected to the device. Using ssh-client one enters the device and runs
utilities, which help to upgrade the basic software.
3. Upgrade using the nfs-Image of the root file system
The following preparations should be done on the server side:
•
tftp–server which gives the core;
•
nfs-server with prepared root file system;
•
dhcp-server which gives the address of the core and the root file system on request.
The device is put into loading from «DHCP» mode, and the software is loaded. Then the
same actions are performed as described in the variant of «Upgrade from USB-storage». In
