Extension by: dmoerner
Comments: This package includes a script written by dmoerner which will
automatically fetch the source code for the rt2860sta wireless
internet driver. It will compile the code against the running
kernel and then create a portable package that contains the
binary in /tmp.
Requires compiletc and linux-headers-2.6.26
Please note that this currently depends on the .tce of the
above dependencies because it is itself a .tce; however,
to save memory you should feel free to manually use the .tcz
versions of the compile tools if available.
------------
Example howto:
$ compile-rt2860sta.sh
$ tce-load /tmp/rt2860sta.tce
$ modprobe rt2860sta
After making the binary package you no longer need the source.
The binary needs wpa-supplicant.tce to fully work.
