4.2.4 Redboot and Firmware Update
The MWI-5000 System includes a utility to manage the firmware update process,
which uses the Trivial File Transport Protocol (TFTP) to upload the revised
firmware. The following describes the procedure for performing the update.
A TFTP server is required to accomplish these updates. The flash update uses a
TFTP client on the AP to download the new firmware image from a TFTP server
on the network.
4.2.4.1
Updating Redboot
Set up a TFTP server on either a Linux or Windows system and connect it to the
network.
With the MWI-5000 booted to normal mode enter use TFTP to copy the new
Redboot image to the unit. It is recommended that the /tmp directory be used:
tftp –r <redboot file> -l <redboot file> hostaddr
Ex: tftp –r X890-ixp425-le-gnu_redboots.bin –l X890-ixp425-
le-gnu_redboots.bin 192.168.1.1
Once the file has been transferred, use the dd command to load it into the flash:
dd if=/tmp/<redboot file> of=/dev/mtdblock0
The output of this command should show:
651+1 records in
651+1 records out
It is important that the records in and out match with 651+1 being the output. If the
numbers do not match then Do Not Reboot the unit. Ensure the Redboot filename
is correct (not compressed with gzip or some other issue) and retry the dd
command. If necessary repeat the TFTP sequence to re-copy the file to the unit.
Once the process is completed successfully, the unit can be rebooted.
4.2.4.2
Update from the Command Line
Setup a TFTP server on either a Linux or Windows system and connect it to the
network.
Copy three image files (XXX_ixp425-le-gnu_waps.jffs2, XXX_ixp425-le-
gnu_rootfs.jffs2, and XXX_ixp425-le-gnu_kernel.bin, where XXX is the build
number) to the TFTP server directory (/tftpboot on Linux).
Start the AP and configure its IP address so it can reach the TFTP server.
Type flash at the AP command line prompt ( IXP425> ).
