BCM43xx Linux Driver Project
|
||||
============================
|
||||
|
||||
About this software
|
||||
-------------------
|
||||
|
||||
The goal of this project is to develop a linux driver for Broadcom
|
||||
BCM43xx chips, based on the specification at
|
||||
http://bcm-specs.sipsolutions.net/
|
||||
|
||||
The project page is http://bcm43xx.berlios.de/
|
||||
|
||||
|
||||
Requirements
|
||||
------------
|
||||
|
||||
1) Linux Kernel 2.6.16 or later
|
||||
http://www.kernel.org/
|
||||
|
||||
You may want to configure your kernel with:
|
||||
|
||||
CONFIG_DEBUG_FS (optional):
|
||||
-> Kernel hacking
|
||||
-> Debug Filesystem
|
||||
|
||||
2) SoftMAC IEEE 802.11 Networking Stack extension and patched ieee80211
|
||||
modules:
|
||||
http://softmac.sipsolutions.net/
|
||||
|
||||
3) Firmware Files
|
||||
|
||||
Please try fwcutter. Fwcutter can extract the firmware from various
|
||||
binary driver files. It supports driver files from Windows, MacOS and
|
||||
Linux. You can get fwcutter from http://bcm43xx.berlios.de/.
|
||||
Also, fwcutter comes with a README file for further instructions.

Please note that PIO transfers are slow (compared to DMA).
|

|
||||
Also note that not all devices of the 43xx series support PIO.
|
||||
The 4306 (Apple Airport Extreme and others) supports PIO, while
|

the 4318 is known to _not_ support PIO.

|

Only use PIO, if DMA does not work for you.
