This is the firmware for the Atheros ar9170 802.11n devices. The firmware, carl9170.fw, can be used with the carl9170 Linux driver or the tools supplied in the repository.
To build the firmware you will need an SH-2 toolchain. You can use the makefile in this repository to build your own toolchain:
$ make -C toolchain
but be aware that this will take some time and requires about 3-5 GiB disk space.
The firmware configuration and build process requires the following tools and libraries:
-
gcc 6.0+ (including library and header dependencies)
-
bison/flex
-
cmake 3.8+
to start the configuration, run:
$ autogen.sh
The configuration is based on the Linux's KConfig utility CLI.
For each configurable option, a prompt will appear. To choose
the default/previous option simply hit <Enter>-key on your
keyboard.
If you encounter the error:
../toolchain/inst/bin/sh-elf-objcopy: 'carl9170.elf': No such file
, run
$ make carl9170.elf
if you want to "install" your own firmware, you can either do this manually, or by executing:
# autogen.sh install
This will place a copy with the right filename [adds API rev] into /lib/firmware/[the default path on most Distributions].
If you have any patches, you should write to linux-wireless@vger.kernel.org and include "carl9170" in the subject line.
