Hi,
I am trying to understand why my FreeBSD router with a new PCI->PCMCIA
bridge is working. From what I read, a few things are missing.
On my $.6-Stable machines (last cvsup'ed a few weeks after 4.6-Release
came out) I installed a Siemens SpeedStream PCI->PCMCIA bridge two days
ago. I have an Orinoco Silver PCMCIA card. The Siemens card has a big
PLX on its chip. Everything just "worked" after making a few additions
to the kernel, rc.conf etc. After being up for a few days, I had a
problem (wi0: watchdog timeout) after the second day (the router is up
all the time.)
I started investigating and can't explain why it ever worked. A reboot
"fixed" everything, my laptop (Win2K) can get to work using the wireless
connection again. Since I'm passing traffic, I'll worry about the
watchdog timeout later. I'd like to understand why it works at all.
What doesn't make sense is when I boot, I get an error from pccardd
complaining that /dev/card0 isn't configured:
pccardd[571]: fatal error: no PC-CARD slots
Looking at dmesg, there is no pcic nor pccard messages. The Orinoco and
Siemens both show up as wi0:
wi0: <Siemens SpeedStream> port 0xec00-0xec3f,0xec80-0xecff mem
0xfdfff000-0xfdffffff irq 9 at device 7.0 on pci1
wi0: 802.11 address: <deleted>
wi0: using Lucent Technologies, WaveLAN/IEEE
wi0: Lucent Firmware: Station 6.06.01
What I expected, from checking out the archives and from using a similar
box in work (but with an ISA->PCMCIA adapter) would be for pccard and
pcic to show up in dmesg, rc.pccard to succeed when calling pccardc to
configure memory etc. and pccardd to find /dev/card0.
My _guess_ is that this bridge makes wi0 look like a traditional PCI card.
Various config files etc are below:
mcambria# cat /etc/start_if.wi0
/usr/sbin/wicontrol -i wi0 -n adhoc
/usr/sbin/wicontrol -i wi0 -q adhoc
/usr/sbin/wicontrol -i wi0 -s MikeC-BSD
/usr/sbin/wicontrol -i wi0 -c 1
/usr/sbin/wicontrol -i wi0 -p 1
/usr/sbin/wicontrol -i wi0 -f 10
ifconfig shows that there is no carrier:
mcambria# ifconfig wi0
wi0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 172.16.6.1 netmask 0xffffff00 broadcast 172.16.6.255

>>>>> status: no carrier
ssid adhoc 1:adhoc

My kernel has:
device pcic
device card
mcambria# pccardc dumpcis
0 slots found
rc.conf also tries to bring up wi0 like any other ethernet adapter:
network_interfaces="vx0 xl0 wi0 lo0"
ifconfig_xl0="inet 172.16.8.1 netmask 255.255.255.0"
ifconfig_wi0="inet 172.16.6.1 netmask 255.255.255.0"
#
ipv6_network_interfaces="xl0 wi0"
ipv6_ifconfig_xl0="3ffe:b80:9b3:8::1 prefixlen 64"
ipv6_ifconfig_wi0="3ffe:b80:9b3:6::1 prefixlen 64"
Should I be doing this elsewhere?
Thanks for any help.
