RedBoot> reset

After this command, there should be a normal boot, you can also go to RedBoot

Useful commands:

fis list –shows the contents of Flash memory

fis list –c –d –shows the contents of Flash memory and Checksum

6.1

Create a copy of the operating system and configuration

settings

In the directory

/dev/mtd/IXP4XX-Flash.0

Located a file (character device) with the whole 16 MB of flash files.

For example you can copy from him everything without RedBoot file:

dd bs=$((0x20000)) if=/dev/mtd/IXP4XX-Flash.0 of=input_file skip=3

In this way we write down flash image to RAM.

If we want to write down flash image to local computer we should execute on this computer following

command:

nc –l 1234 > flash_image

and on router we execute:

dd bs=$((0x20000)) if=/dev/mtd/IXP4XX-Flash.0 skip=3 | nc xxx.xxx.xxx.xxx

1234

where: xxx.xxx.xxx.xxx local computer IP address and 1234 is the port number of this local computer

(skip=3 skips 3 RedBoot blocks, it means that specific setting for hardware router version are not

copied.)

You can do the opposite direction (MultiLink routers only!):

dd bs=$((0x20000)) of=/dev/mtd/IXP4XX-Flash.0 if=output_file seek=3

For MicroRouter update have to use RedBoot application p.6

Warning!

Do not just wrong directions: skip=X skips blocks to the entrance,

seek=X starts recording from the block X to exit bs=block size, if=input

file,

of=output file. ???????

Read-only filesystem" means that a block is protected

record, you need to do then RedBoot eg

fis unlock -f 0x50060000 -l 0xFA0000

dd output can also refer to the pipe (if we do not give of = XXX)

description is in google man dd.

Backup and Restore Features

The router's Flash memory has been set aside two areas of configuration:

- Conf (core area which is read the current configuration)

- Conf2 (additional area to which you can save the configuration of the reserve)

To save the current configuration in addition to conf2 area should be from the console command:

/etc/UI/scripts/backupGUI

To recover the reserve configuration is the console command:

1 2 ... 30 31 32 33 34 35 36 37 38 39 40 41
