Howto fconfig redboot from shell
http://openfsg.com/forum/viewtopic.php?f=7&t=4926



If there is a partition created between "kern2" and "RedBoot config" the fsg-3 can't manage the recovery procedure.
It seems "RedBoot" needs "RedBoot config" on MTD4 to get his IP&BootP and TFTP information to load the recovery image.

It looks like the recoverytool needs the RedBoot config at MTD4.

HowTo flash the Nightwing firmware using RedBoot

Lugro-Wireless Task Force - Redes de Despliegue rápido

RedBoot is a complete bootstrap environment for embedded systems. Based on the eCos Hardware Abstraction Layer. RedBoot has many features, including the use of the command line interface (CLI).

Through the CLI we can manipulate the flash memory of our device (in our case the router), we can also upload and download the images to flash memory through a tftp server.

Redboot can be access via a serial interface or Ethernet.

FSG-3 has 2 Ethernet Engines

NPE-B/eth0 and NPE-C/eth1

NPE-B is connected to a 4 Port Switch, only three of them go from PCB to outside
NPE-C is connected to the outside

If the platform has flash memory, RedBoot can use this for image storage. Executable images, as well as data, can be stored in flash in a simple file store. The fis command (fis is short for Flash Image System) is used to manipulate and maintain flash images.
