DSP Loadware Upgrade
Similar to the loadware upgrade described above, the DSP loadware may also
be upgraded via two methods, across the network from an FTP server or
locally from the PCMCIA disk.
DSP Loadware upgrade from PCMCIA Flash card
Using this method the loadware binary is first copied onto the PCMCIA flash
card on the Agent Greeting Card. It is then programmed into the flash area of
each DSP section.
To use this method, first FTP into the IP address of the Agent Greeting card.
The FTP username and password are the same as that of the shell, as
described above. Change directory to the “/A:” drive and copy the DSP
loadware file onto the Agent Greeting Card in binary format. Logout of the
FTP session.
From the VxWorks shell execute the command “upgradePCMCIAdsp” as
described below.
The DSP loadware file is loaded via FTP from a file server. The file is stored
in a dedicated 2 MB flash device in each DSP section. The same loadware
strategy is implemented for the Agent Greeting on-board DSP section and the
DSP cards. No special recovery mechanism is required. If the upgrade fails
for some reason (e.g., incorrect file used), the DSP will fail to reboot and the
upgrade must be performed again. The upgrade is performed by running the
upgradePCMCIAdsp command in the VxWorks shell as follows:
-> upgradePCMCIAdsp <dsp no>,“/A:lmag84aa.bin”<CR>
Updating sector:
0..1..2..3..4..5..6..7..8..9..10..11..12..13..14..15..16..17..18..19..20..21..22..23..24..25..
26..27..28..29..30..31..
After a successful upgrade, the following messages are printed (along with
channel deletion/creation messages for existing channels):
DSP Checksum OK!!!
DSP Load upgraded OK
value = 0 = 0x0
After a failed upgrade, the following messages are printed:
