[Berlin-wireless] DIR-300: Flash report

Sa Nov 8 12:57:35 CET 2008

Hey,

hab' von Alina so ein Teil im Tausch bekommen. Wenn die D-Link FW nicht drauf 
ist, kann der RAM-Redboot-Loader nicht geladen werden. Wenn schom mal ein 
DD-WRT redboot drauf war existiert "Redboot Config" mit irgendwelchen 
Einstellungen. In meinem Fall reagierte der RAM-Redboot nicht auf 192.168.1.1 
sondern auf 192.168.20.81. Also:

root at pcnet:/usr/src/dir300-flash# telnet 192.168.20.81 9000
Trying 192.168.20.81...
Connected to 192.168.20.81.
Escape character is '^]'.
DD-WRT> ip_address -l 192.168.1.1/24 

Egal - nachdem ich hab' jedenfalls den Ursprungszustand wiederhergestellt 
hatte (D-Link-Redboot + D-Link-Firmware) - dann lief es durch (zwischendurch 
das ip_address wie oben ausfuehren).

Details wollte ich hier hin stellen http://blog.freifunk.net/ aber das will 
nich. Also Textdatei anbei.

I recently exchanged a spare Atheros MiniPCI-Express wireless card for a new router. The box says, it's a D-Link DIR-300 currently available in the supermarket for approx. 30,-- Euros. After unboxing, I removed the label cying "!Stop, insert CD first" and attached an ethernet cable to the WAN port. According the the previous owner, I can telnet into redboot by using these commands. Start ALT-F2-"kdesu konsole" and type in:

killall NetworkManager;killall NetworkManagerDispatcher
killall dhcdbd;killall dhclient
ip addr add dev eth0 192.168.20.80/24
ip link set dev eth0 up
while true;do sleep 1;telnet 192.168.20.81 9000;done
  switch on router, wait for "Escape is", press [ret]

Note, that this is a first test and there are other ways to stop DHCP from interfering a static IP address on the Ethernet port. The following steps are done on my netbook which runs under Kubuntu/Hardy. I also added the group "src" to my linux login using the Kubuntu user manager. Your Linux may vary...

After rebooting the netbook, I searched for the easy-flash tool announced by alina in order to flash ff-lucy on that thing. Docs on the DIR-300 and ff-luci can be found here:

http://wiki.openwrt.org/OpenWrtDocs/Hardware/D-Link/DIR-300
http://luci.freifunk-halle.net

Now start by issueing ALT-F2-konsole and grab/unpack alinas script:

cd /usr/src
wget http://x-alina.freifunk-potsdam.de/downloads/dir300-flash/dir300-flash-0.9.5.tar.gz
tar xvzf dir300-flash-0.9.5.tar.gz
cd dir300-flash
sudo mkdir /usr/share/dir300-flash
sudo chgrp src /usr/share/dir300-flash
sudo chmod g+w /usr/share/dir300-flash
sudo chgrp 
./dir300-flash.sh

Which complains something about "no tftp found". So I do:

sudo apt-get install tftpd-hpa
sudo chgrp src /var/lib/tftpboot
sudo chmod g+w /var/lib/tftpboot
sudo kwrite /etc/default/tftpd-hpa
  [change to RUN_DAEMON="yes"]
sudo /etc/init.d/tftpd-hpa start
./dir300-flash.sh

Which says something about "No kernel". So I do:

wget http://dev.luci.freifunk-halle.net/freifunk-snapshots/atheros/openwrt-atheros-root.squashfs
wget http://dev.luci.freifunk-halle.net/freifunk-snapshots/atheros/openwrt-atheros-vmlinux.lzma
./dir300-flash.sh

Which mutters blabla about the IP addr of eth0. So I

sudo kwrite /etc/network/interfaces
  [add the following statement]
iface eth0 inet static
        address 192.168.1.2
        netmask 255.255.255.0
        up ip addr add dev $IFACE 192.168.20.80/24
        up ip addr add dev $IFACE 192.168.0.2/24
        down ip addr del dev $IFACE 192.168.0.2/24
        down ip addr del dev $IFACE 192.168.20.80/24
  [now restart eth0]
sudo ifdown eth0
sudo ifup eth0
./dir300-flash.sh

Which starts flashing that thing (needs some minutes). After successful flashing, you may "telnet 192.168.1.1" as a first step while eventually http://192.168.1.1/ may also work for you.

----------

For my special device, there was no original firmware on it. I needed to restore the D-Link FW using the emergency web UI under http://192.168.20.81/ to be able to flash successfully. Heres what is displayed, if no D-Link FW on the device:

RedBoot> load ap61.ram.dir300-flash
Using default protocol (TFTP)
Entry point: 0x800410bc, address range: 0x80041000-0x800680d8
RedBoot> go
[fload] execution fail! [go] abort...
