Hello,
I have a compaq R300z (okay, I'm sorry already!) running
freebsd-amd64 current. I recently tried to use ndisulator for the
built in broadcom wireless and used the 64 bit windows drivers to try
to generate a loadable module for the wireless device. I have had some
trouble generating the loadable module, though. I last updated world
and the kernel on Monday.
I've tried searching the freebsd-amd64 and freebsd-current lists, and
I've tried to search using google. So far I can't find anything to
help. Has anyone managed to get this beast working? Any help would be
appreciated. I will paste an overview of what I've tried below:
Here is the device info:
root@localhost# pciconf -lvvv
none3@pci2:2:0: class=3D0x028000 card=3D0x12f4103c chip=3D0x432014e4 rev=3D=
0x03 hdr=3D0x00
vendor =3D 'Broadcom Corporation'
device =3D 'BCM4306 802.11b/g Wireless LAN Controller'
Copies of the driver files that I am using can be found at
http://blackk.union.edu/~black/freebsd/BCMWL564.SYS
http://blackk.union.edu/~black/freebsd/netbc564.inf.ascii
This is a 64 bit driver, and the inf file was converted to ascii using icon=
v.=20
Here is the message I get when I use ndisgen:
Compiling stub... done.
Linking loadable kernel module... /usr/bin/ld: windrv_stub.o:
relocation R_X86_64_32S can not be used when making a shared object;
recompile with -fPIC windrv_stub.o: could not read symbols: Bad value
linking failed. Exiting.
I read through the ndisgen script to try to figure out what it was
doing. I then did this (I added -fPIC):
/usr/bin/cc -D_KERNEL -DDRV_DATA_START=3DBCMWL564_SYS_drv_data_start
-DDRV_NAME=3DBC MWL564_SYS -DDRV_DATA_END=3DBCMWL564_SYS_drv_data_end -I.
/usr/share/misc/windrv_stub.c -data -symbolic -c -o windrv_stub.o
-fPIC
/usr/bin/ld -Bshareable -d -warn-common -o BCMWL564_SYS.ko
windrv_stub.o windrv.o
/usr/bin/ld -r -d -warn-common -o BCMWL564_SYS.o windrv_stub.o windrv.o
(The files windrv_stub.o and others were created when ndisgen called
ndiscvt so I just left them alone.)
When I do this the file compiles and links with no error messages. It
creates a file called BCMWL564_SYS.ko. When I try to load the file
using kldload I get these messages:
kldload: can't load /tmp/broadcom/BCMWL564_SYS.ko: Exec format error
and from the console window:
kldload: Unsupported file type
kldload: unexpected relocation type 7
link_elf: symbol windrv_load undefined
Any ideas?
Sincerely,
Kel
