bcm43236 complient in the compat-wireless-3.6.81???

[Naughtboy]

hi erveryone !
i  have a usb dongle bcm43236
i wan to trsan it in the mips bcm47xx
but i search in hte www , and didn't find the driver for bcm43236
linux soucre code !!
i have find and study  http://wireless.kernel.org/en/users/Drivers/b43

and  find   http://wireless.kernel.org/en/users/Drivers/b43 do nothing
usefull !!

anyone can do one hand?
thanks advance !!

Hi,

I assume you have a bcm43236 rev 2 as all the bcm43236s connected to a
MIPS BCM47XX SoC I saw have that rev.  There is probably no open source
driver for the bcm43236 rev 2, just rev 3 is supported by brcmfmac.

This device is supported by brcmfmac:
http://wireless.kernel.org/en/users/Drivers/brcm80211

The source code is in a recent linux kernel or in backports:
http://drvbp1.linux-foundation.org/~mcgrof/rel-html/backports/

It is in the kernel tree under
'drivers/net/wireless/brcm80211/brcmfmac'. We only support rev 3 because
rev 2 and earlier do not have enough memory to run fullmac firmware.
However, I have not found any rev 3 on the market. If you have please
let me know.

Could you say something more about rev 2? How does it work with
internal Broadcom driver? Is the firmware stored somewhere else? Does
it have some another kind of memory?

Apart from the firmware storing issue, is the communication between
driver and hardware the same?

Your "english" is difficult to follow. Anyway, we are talking about chip
revisions. It has nothing to do with linux kernel versions. However, if
you want to use it on an ancient 2.6.22 kernel you better use the
backports that Hauke referred to. Unfortunately for BRCMFMAC it only
goes back to 2.6.29. Maybe in general backports only goes back till
2.6.24 (not sure). If you get the driver working it will spill out in
the kernel log whether your bcm43236 has a good *chip* revision, ie.
chiprev >= 3.

It has a split-mac design. So at one end the spectrum there is
mac80211-type drivers and at the other side are fullmac drivers like
brcmfmac. rev 2 driver sits right in the middle of that with part of the
802.11 stack running on the host and part on the device. This device has
not enough memory to run the fullmac firmware.

Thanks for your explanation. I think I understand now what means
WLC_HIGH, WLC_LOW, WLC_SPLIT you can see in
0001-Staging-Add-initial-release-of-brcm80211-Broadcom-80.patch. I
guess that softmac devices need WLC_HIGH and WLC_LOW, split devices
(like BCM43231) need WLC_HIGH (because LOW is implemented in firmware)
and full MAC devices need none of above.

As questions about these chipset come over and over, I added a new
section to the brcm80211 wiki page:
http://wireless.kernel.org/en/users/Drivers/brcm80211#Unsupported_Chips
I hope it's OK for you.

Btw. if anyone is interested, I've written a minimal user-space app to
read device info (DL_GETVER) from Broadcom USB dongle.

Yeah. The brcmfmac driver for fullmac devices is a separate driver
design based on bcmdhd.

Fine and thanks. Let's see how often another such question pops up.

I see fixed definition for vendor and device id. Given that they differ
from what we have in brcmfmac it may be good to use command line
argument(s) for these.

I don't see any real usage possibilities for this app, I just wanted
to see how "libusb" works and see what's really inside of my WNA3100.
I don't think anyone is really going to use it ;) Just shared it since
I already got it ;)

Well, we could put it on the wiki page so people can check before asking
