Planned Support for BCM 43162 [14e4:43ae] rev 02 ?

[Jan Sobotka]

Hello,

is planned to add support for BCM 43162 [14e4:43ae] to b43 in near future? Unfortunately I bought the notebook with this WLAN card. Bug reported here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1576815 I'm willing to help, for example with testing.

Regards.

is planned to add support for BCM 43162 [14e4:43ae] to b43 in near future? Unfortunately I bought the notebook with this WLAN card. Bug reported here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1576815 I'm willing to help, for example with testing.

Noone is working on new hw support right now, but essential question
is what PHY is used in this chipset. Can you load bcma for this card
and get us bcma (and potentially b43) logs?
modprobe bcma
echo "14e4 43ae" > /sys/bus/pci/drivers/bcma-pci-bridge/new_id
dmesg | egrep "bcma|b43"

Don't drop ML from To/Cc. It's a bad habit and there are other ppl who
are interested in this and may be able to help as well.

Hi,
sudo echo "14e4 43ae" > /sys/bus/pci/drivers/bcma-pci-bridge/new_id
bash: /sys/bus/pci/drivers/bcma-pci-bridge/new_id: Permission denied
lsmod | egrep bcma
bcma 53248 0
than dmesg | egrep "bcma|b43" produce no output.
Do you have some advice for echo "14e4 43ae"... command modification?

Not sure why it happens. Could you try
sudo su
echo "14e4 43ae" > /sys/bus/pci/drivers/bcma-pci-bridge/new_id
instead?

Sorry, I used reply instead reply to all. It was not intention.

Great, now it works. Output:

So this is device with BCM4335 chipset which is a FullMAC one AFAIK.
It may be supported by brcmfmac. There is already support for BCM4335
in brcmfmac but it was developed for SDIO devices only. I don't think
we ever met BCM4335 on PCIe device.

You may try:
sudo su
rmmod bcma
echo "14e4 43ae" > /sys/bus/pci/drivers/brcmfmac/new_id
dmesg | grep brcmfmac

However I think brcmfmac may need some extra changes to support
BCM4335 on PCIe. Lets also see if Broadcom team can help us with this.

It does have an ARM core, but for fullmac we need RAM as well and I
don't see that listed. So I guess it is a 43162 and needs softmac
driver. Also could not find any fullmac firmware for it. The only thing
I found was a hybrid wl driver release for it.

sudo echo "14e4 43ae" > /sys/bus/pci/drivers/bcma-pci-bridge/new_id

bash: /sys/bus/pci/drivers/bcma-pci-bridge/new_id: Permission denied

Not sure why it happens

echo "14e4 43ae" | sudo tee /sys/bus/pci/drivers/bcma-pci-bridge/new_id

That should work. The reason why the other didn't work is because you
were running the 'echo' command as root, but then the re-direction was
being done by a shell that was running as a user.

`sudo` is not a magic shell built-command, it's just a suid-root binary,
and merely passes on the arguments the shell gives it.
