[Madwifi-devel] xscale compilation warning

[Nitin M. <sum...@gm...>]

Hi All,

I am trying to cross compile madwifi on kernel 2.4.25 (snapgear linux
distro) for  xscale (ixp 425 specifically).

I can compile the source code but am having 2 issues.

1) While compiling it gives a warning 
cc1: warning: switch -mcpu=xscale conflicts with -march= switch

I have set the necessary KERNELPREFIX, TARGET (=xscale-be-elf) and TOOLPREFIX 

Is this an issue with toolchain for arm I have ?? can anyone conform
the toolchain with which this doesnt come ?

2) Bigger problem is that when I download the necessay .o's onto the
board the  ath_pci.o is crashing .. i.e insmod itself is giving a
segmentation fault ..

some points I will like to mention:
-> I have recompiled hal with the correct tool chain also I have (have
source code)

dump below at the last

Can someone please tell me what I am missing here ??

or how to go about finding whats causing this segmentation fault ?

Cheers,
Nitin

DUMP
