More on the Orinoco + XI-825 + StrongARM platform...

[Ben Greear]

Well, I feel I'm very close to having my little embedded
strongarm device (cerfcube) talking to the world...but it's not quite
working yet!

I copied the driver/wireless/* source from the 2.4.17 kernel
into a 2.4.9 kernel and made the necessary changes to port it
over (had to manually do the min/max methods because 2.4.9 doesn't
seem to have them)..

The cerfcube's pcmcia scripts are a bit wierd, but I manually
configured things as best I could.

First, I added entries to the config file:

device "orinoco_cs"
   class "network" module "orinoco_cs"

...

# This is the XI-825 card from ZCOMAX
card "IEEE 802.11 Wireless LAN/CF Card"
   manfid 0xd601, 0x0005
   bind "orinoco_cs"

When I insert the card, I see this in /var/log/messages:

It doesn't seem to set my ESSID or any other variable I set in wireless.opts,
so I manually try to poke it in with iwconfig.  The end results:

[root at CerfLinux pcmcia]$ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

Warning : Device eth1 has been compiled with version 11
of Wireless Extension, while we are using version 13.
Some things may be broken...

So, I think I'm really close.  The problem is that I still can't
ping my other machine running in Ad-Hoc.  (That other machine talks
to a third, though, so I think it's the cube's fault.)


[root at CerfLinux pcmcia]$ ifconfig eth1
eth1      Link encap:Ethernet  HWaddr 00:60:B3:69:56:67
           inet addr:172.1.1.100  Bcast:172.1.255.255  Mask:255.255.0.0

           Interrupt:43

[root at CerfLinux pcmcia]$


The interesting thing is that when I ping between the other machines, I
see packets received on the cube.  When I ping from the cube to the laptop,
while sniffing the wireless port on the laptop with tcpdump, I see this:


[time-stamp] 0:60:b3:69:56:67 > Broadcast null I (s=85,r=85,C) len=50
(more of the same)


I am open to any suggestions you all might have!

Thanks,
Ben
