Hi,

I created a new package for the (legacy) rt73 driver from rt2x00.serialmonkeys.org using the rt2570 Makefile as a basis. After some tweeking got it to compile (for brcm47xx-2.6) and it actually works too!

The thing was that I had to manually add "EXTRA_CFLAGS" with a lot of options in order to make it compile. The rt2570 did not have it but somehow it was not required there.

Any tips for avoiding this?

So here's the "packages/rt73/Makefile":

The makefile below works for me. You have to manually fix the PKG_BUILD_DIR and PKG_MD5SUM.

include $(TOPDIR)/rules.mk
include $(INCLUDE_DIR)/kernel.mk

Hi is it possible that you can make an ipkg of this driver and put it online.

I have looked into doing this myself but its to hard for me. :-)

The discussion might have continued from here.
