[edit] Installation

linksys-wrt54g2v11 folder (14929): flashing.txt instructions for updating RedBoot and loading dd-wrt are below.

Since Linksys (or the firmware vendor, maybe gemtek or cybertan) disabled networking within the redboot bootloader (and also the partition management), we must replace it using a serial console (baudrate 9600).

First set a static IP (e.g. then run a local tftp server.

  • Enter the following line into the redboot with serial console to enable network access:
ip_address -l -h
  • Start a new redboot:
load -r -b 0x80041000 redboot_ap65.ram
  • Start the new bootloader:
fis init 
load -r -b 0x80080000 redboot_ap65.rom
fis create -l 0x10000 -e 0xbfc00000 RedBoot
  • Create linux partition:
fis init
load -r -b 0x80041000 linux.bin
fis create linux

  • Configure the bootscript with fconfig:
the script must be
fis load -l linux
  • Save the config and type "reset" again to boot up the system

To enter the redboot console with this new bootloader you must push the reset button. This will also allow tftp recovery mode to send a dd-wrt webflash file, using tftp to the bootloader for flashing.
