After a BaB meeting at Southampton some while back where I brought my
GuruPlug and fiddled with some setting because the University network
was down when I got home the Plug no longer worked on my LAN.
I have finally got round to trying to solve the problem.
When connected via a JTAG I get the following information from the GuruPlug.
After booting with no changes:-
sheevaplug-debian:~# ifconfig
eth0 Link encap:Ethernet HWaddr MACaddress
inet6 addr: fe80::f2ad:4eff:feff:158b/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

sheevaplug-debian:~# dmesg |grep fail

btmrvl_sdio_download_helper: request_firmware(helper) failed, error code = -2
btmrvl_sdio_probe: Downloading firmware failed!
sheevaplug-debian:~#
Manually setting up ifconfig thus:-
sheevaplug-debian:~# ifconfig eth0 LAN_IP broadcast 192.168.2.255
netmask 255.255.255.0
sheevaplug-debian:~#
sheevaplug-debian:~# ifconfig lo 127.0.0.1
sheevaplug-debian:~#
Rerunning ifconfig gives:-
sheevaplug-debian:~# ifconfig
eth0 Link encap:Ethernet HWaddr f0:ad:4e:ff:15:8b
inet addr: LAN_IP Bcast:192.168.2.255 Mask:255.255.255.0

After this I can connect over the LAN to the GuruPlug and it works as
before but as soon as I reboot the Plug it no longer works!
My question is how can I make these changes stick? I have tried
changing these 2 files /etc/udhcpd.conf and
/etc/network/interfaces with the connection data but to no effect.
I do not know what the failed messages from dmesg mean but they do not
seem to stop the plug working as normal once ifconfig has been set up.
All help welcome please.
