- BCM43XX Linux Driver Project
- ============================
- About this software
- -------------------
- http://wireless.kernel.org/en/users/Drivers/b43
- b43-fwcutter is a tool to extract firmware from binary Broadcom 43xx driver files.
- Usage
- -----
- b43-fwcutter FILE extracts the firmware from a source FILE to
- the current directory, creating a directory
- "b43" or "b43legacy" with files in it.
- b43-fwcutter -i FILE identify the driver file; print information
- but don't extract.
- b43-fwcutter -w /tmp FILE extract and write firmware to /tmp.
- b43-fwcutter -l prints a list of supported driver source files.
- After extraction, copy the "b43" or "b43legacy" directory to your firmware
- directory (usually /lib/firmware or similar, see below). Alternatively you
- can use the -w option to b43-fwcutter.
- Different distributions use different directories to load firmware from.
- If the driver complains about missing firmware files look for the correct
- directory. For some distributions you have to use /lib/hotplug/firmware
- or /usr/lib/hotplug/firmware but other directories are also possible.
- Because firmware file are stored in big endian, extraction doesn't depend
- on the system you're using. You can use extracted firmware from any driver
- on any system and also copy the extracted files to any other system (e.g.
- if extraction on the target system isn't feasible.)
- Where can I find some driver source files?
- ------------------------------------------
- Please check the references at
- http://www.linuxwireless.org/en/users/Drivers/bcm43xx#devicefirmware
- It is recommended that you extract firmware for both b43 and b43legacy in
- order to support both types of cards on your system.
