Broadcom cards for free

Broadcom cards for free

[Michael Buesch]

Hi,

I've currently got two Broadcom cards to offer for free.
http://bu3sch.de/misc/bcmcards.JPG

The cardbus one is a WPC300N V1 802.11n card.
It can be used for development of the b43 N-PHY code.

The USB one is BCM4320 which works over RNDIS-WLAN.
This device is disassembled and the EEPROM, which contains
the on-board operating system, is unsoldered and connected through a pinheader.
That means it can be read and/or reprogrammed outside of the device.
The RF-shield on the RF-side of the board was removed.
The device should work properly. It properly registers to the kernel, but I did
not try if it works with the rndis-wlan driver.

Greetings, Michael.

Sounds interesting... especially now that N-PHY is actually being
reverse-engineered (or is it?).

The modded 4320 is an attempt to replace the built-in OS and use it
with b43 as a softmac device... am I right?

I don't know if somebody is working on it, but the card could be useful for
somebody working on it.

No, it was used to read the EEPROM. There were no attempts to reverse-engineer
and rewrite the EEPROM, however one can do that with this device.
It contains about 300kb data, so it's probably hard to reverse engineer.
However, I think there's no need to start over from zero, because most parts
of the device should be known. They're most likely just running their portable
driver kit on it.

I'm still working on it, although a lot of my time is taken in testing
openSUSE 11.2 pre-release code. As the release date is Nov. 12, that
will soon be over.
