 |
|
I been at this card for many hours but still can't quite get it running. Looks like I'm almost there but now I'm stuck. I hope someone here in the forum can help me. It seems to me that the PCMCIA part is working, I have another card, an IBM 10/100 EtherJet CardBus adapter which works. It is a 32-bit card whereas the 3Com card is 16-bit. Could it make a difference?
On to the problem. I get these errors when I try to start the card: | Code: | sterna ~ # atmel_fwl eth3 /lib/firmware/atmel_at76c502_3com.bin
atmel_fwl: eth3 is not an Atmel interface.
sterna ~ # /etc/init.d/net.eth3 start
* Starting eth3
* Loading networking modules for eth3
* modules: wpa_supplicant essidnet iptunnel ifconfig dhcpcd apipa
* wpa_supplicant provides wireless
* ifconfig provides interface
* dhcpcd provides dhcp
* Bringing up eth3
* dhcp
* eth3 does not exist [ !! ] |
The reason i use eth3 is that I have other network cards configured for eth0-2, which all work, eth1 beeing a wlan card.
I have no idea what to do next. One thing that I don't understand is how the system knows which network card to map to which ethX. If I have more than one card active how does it know which one is eth0 and which one is eth2? The configuration for both of them look exactly the same (see /etc/conf.d/net below). It somehow magically seems to select the right one. I did configure them in the order eth0-eth2 but does that matter?
Any ideas?
Below are things that might be relevant.
Note
eth1 is not the 3Com card, it is the built in wireless card.
eth2 is not visible in the lists below because the card is not present.

[solved:] there are two drivers for the Atmel at76c50x in the kernel. both must be selected.

Seron,
The logical names eth0, eth1 ... are allocated in the order in which the interfaces are initialised.
When you remove the card that is usually eth2, eth3 will be discovered as eth2, unless you remove eth2 after all four interfaces have been configured,
Your | Code: | sterna ~ # atmel_fwl eth3 /lib/firmware/atmel_at76c502_3com.bin
atmel_fwl: eth3 is not an Atmel interface. |
fails because there is no eth3.

I see. Then it must be that the card is not fully discovered. I write fully because it is discovered by cardctl but the interface is not listed by iwconfig. How can I know if eth2 is correct in | Code: | | sterna ~ # atmel_fwl eth2 /lib/firmware/atmel_at76c502_3com.bin |
Do I just pick the next free ethX in line listed by iwconfig or is there another way to find out the interface?
I don't understand the order in which these things should come. If I modprobe the nic driver should the interface become available even though the card firmware has not yet been loaded? Then it would be obvious which interface to use for the firmware. Or is it supposed to be the other way, to load the fw into the interface to make the interface available?
[EDIT: typo]
