D-Link DWL-650+ Problems

pdepass · 11-12-2003, 09:00 PM

I've abandonded my new kernel attempts..

After tedious searching, reading, testing, etc. I found a few good forums with people having the same problems I am.

Here are a few I've found, in case anyone is interested:

http://sourceforge.net/forum/forum.p...&forum_id=7049

And... the most important:

http://groups.google.com/groups?hl=e...l%3Den%26lr%3D

My oh my! That last one really helped... Bascially, my Cardbus adapter (the TI PCI1130) does not support PCI IRQ's, which the Linux 2.4 pcmcia drivers want/need.

By using the pcmcia-cs drivers, I still get the warning about no IRQ found, but I am told it can be safely ignored...

Not too sure now as the acx100 readme says it requires 2.4 kernel pcmcia drivers...

OK, here's the status. I'm still at it

It is very doubtful the kernel's pcmcia drivers will (ever) work with my laptop. My TI 1130 just doesn't (seem) to support PCI IRQ's.

I've installed the latest pcmcia-cs beta drivers 3.2.6, and they get my cardbus slots up and running just fine. Now, the problem comes to client drivers.

David Hinds has suggested I use his dummy_cb driver for the DWL-650+. This driver is basically a "point enabler" that allows people to use HotPlug PCI drivers (which normally rely on kernel pcmcia drivers).

Here's what I am getting when I insert the acx100:

Code:

cs: cb_alloc(bus 5): vendor 0x104c, device 0x8400
cs: cb_config(bus 5)
fn 0 bar 1: io 0x100-0x11f
fn 0 bar 2: mem 0x60030000-0x60030fff
fn 0 bar 3: mem 0x60020000-0x6002ffff
irq 3
cs: cb_enable(bus 5)
bridge io map 0 (flags 0x21): 0x100-0x11f
bridge map 0 (flags 0x1): 0x60020000-0x60030fff
dummy_attach(device 05:00.0)

dummy_cb recognizes the card, and sets up memory for it.

Now, when I "modprobe acx100_pci":

Code:

...
acx100_init_module: TI acx100_pci.o: Ver 0.2.0pre6 Loaded
acx100_probe_pci: acx100: Cannot reserve PCI memory region 1 (or also: are you sure you have CardBus support in kernel?)
Trying to free nonexistent resource (60030000-00000000)
Trying to free nonexistent resource (60020000-00000000)

"lspci -v" with the card in gives some clues:

Code:

pcilib: Cannot open /proc/bus/pci/05/00.0
Unable to read 64 bytes of configuration space.
...

Not sure if anyone here can help, but I have also been posting on the pcmcia-cs forum at http://sourceforge.net/forum/forum.p...&forum_id=7049

I know it's been a while, but I've been pretty busy lately. I got it.

If you install apt rpm (whether you use a front end or not, doesn't matter), include

rpm http://apt.sw.be redhat/9/en/i386 dag

it has a full working version of the acx100 drivers pre6 for red hat 9, kernel version 2.4.20-24.9 as well as the kernel package for that release.

recompile the kernel with wireless internet support, add the module to your loaded modules, you're ready to go.

I know this isn't as "fun" as building it all on your own and getting it to work right, but I had given up for quite a while until I ran into this.

hope you have some luck with it.
