Installation

You are doing everything at your own risk! Nobody is responsible for what you are doing. Don't do it if you don't know what you are doing! Incomplete BETA version of text!

Operating system

  • Set your IP: 10.10.12.2 (alt. 192.168.1.101)
  • Mask: 255.0.0.0

TFTP

  • Start server listening on: 10.10.12.2 (alt. 192.168.1.101)

Putty

:redboot
putty.exe -telnet -P 9000 10.10.12.72
goto redboot 

RedBoot

  • Verify config ( last point where you can stop the procedure )

fconfig -l

  • Clear flash

fis init

  • Agree with format

y

  • Download kernel from TFTP server

load -r -b %{FREEMEMLO} openwrt-atheros-vmlinux.lzma

  • Create partition for kernel

fis create -r 0x80041000 -e 0x80041000 vmlinux.bin.l7

  • Download RootFS from TFTP server

load -r -b %{FREEMEMLO} openwrt-atheros-root.squashfs

  • Check free space

fis free

  • Create partition for RootFS. Replace 0x2E0000 for number you get as difference between last number of free space and the first number. All in hex.

fis create -l 0x2E0000 rootfs

  • Verify partition table

fis list

  • Reboot into OpenWrt

reset

FIXME

Verify OpenWrt installation

  • Telnet to 192.168.1.1 on standard port(23)
  • If it does not work try:

1) Telnet to 10.10.12.72 (alt. 192.168.1.1) on port 9000 to get Redboot prompt

RedBoot> fis load -l vmlinux.bin.l7
RedBoot> go 0x80041000 

2) Now you can see Open Wrt promt.

root@OpenWrt:/# 
3) Thus you have to correct booting procedure. Reboot device
Telnet to 10.10.12.72
RedBoot> fconfig -l 
RedBoot> fconfig boot_script_data

Enter following:

fis load -l vmlinux.bin.l7
go 0x80041000

Save and reboot.

Serial on JP1

  • brown = gnd
  • red, orange = tx and rx (sry, I don't know which is which and now I can't test it)
