BCM43224

[Faissal Bensefia]

Good day all,
To my knowledge the only drivers for this card are brcmsmac and
broadcom-wl, both of which require proprietary firmware, which I'd like
to do without. How can I assist in reverse engineering the BCM43224
firmware? Are there any resources that explain how to use b43-tools?

b43 also has (very) limited support for BCM43224, after all you
e-mailed b43 mailing list.

For open firmware implementation my best suggestion is to contact
OpenFWWF team http://netweb.ing.unibs.it/~openfwwf/

I've attempted to use b43 but on my card but it doesn't work, the module
never loads, despite me removing brcmsmac making sure that everything
has been unloaded and then loading b43, as well as blacklisting
brcmsmac, none of which worked. From what I've read there is meant to be
support but it's not been tested (I don't remember where the site was
but it had a list of Broadcom cards and their support status).

Thanks very much, I'll look into this.

Please be specific.

"the module never loads" - what error do you see after doing "modprobe b43"?

I got it to work, sort of, but ended up upgrading to a new old card, and
I've been VERY happy with it.

I did research and found one of the few N cards that was made for the type
of slot in my older notebook.

I get no error when I do that. When I say the module never loads I'm assuming it hasn't because I have no network connection and network manager doesn't detect a Wi-Fi interface.

Ok, just a follow up, I was looking through my journalctl and found this:
Dec 03 10:29:27 macbook-xubuntu kernel: b43: probe of bcma0:1 failed
with error -524
