brcmfmac driver does not work with a BCM4335 WiFi module

brcmfmac driver does not work with a BCM4335 WiFi module

[Dong Aisheng]

Hi ALL,

I'm verifying BCM4335 WiFi module on i.MX6SL EVK board.
The kernel i ran is latest from:
git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless.git

The firmware is used is from:
git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

NVRAM file is got from the vendor which should work for the module.

But i ran into the following issues, hope somebody can give me some hints.

First, i met error when module is auto loaded, but seems the driver is
still loaded successfully since i found the new WiFi interface with
ifconfig.
But it can not work after run rfkill unblock wlan and a lot error
messages comes out.

I'm wondering if this driver can support bcm4335 well, can anybody
provide some help?

Regards
Dong Aisheng

Below is the log FYI.

I can try. I have used the bcm4335 with a SDIO3.0 controller on a x86 
PC. Looking at an issue right now, but your log does not show that so 
you have a different issue. Could you load the module with parameter 
'debug=0x146'.

Do you  mean the error message during probe is also fine?

I'm using yocto rootfs, seems rfkill is always enabled by default.
I could try another rootfs without rfkill.
But i don't think rfkill should block WiFi driver to work properly.

I tried another rootfs without rfkill, met the same issue when doing
ifconfig wlan0 up, just like 'rfkill unblock wlan'.

I looked into a bit more about the error and found there's CMD timeout
on the bus during SDIO
command transfer.

I'm not sure how this happened, whether caused by host side or wifi driver side.
But for the host, i tried this host driver with another WiFi
card(Atheros AR6103) with same kernel,
and it worked well. So the host driver seems more like ok to me.

Since i'm not familar with the WiFi driver, i wonder if you could
provide suggestion
from WiFi driver layer to see what the issue could be.

Below is the detailed log when run 'ifconfig wlan0 up'

It seem this is the last command being sent. Could you provide file 
contents in /sys/kernel/debug/brcmfmac/mmc*/

Not sure if Yocto mounts debugfs on /sys/kernel/debug. Otherwise you can do:

# mkdir /tmp/debugfs
# mount -t debugfs none /tmp/debugfs

>>>>>>> Hi ALL,
>>>>>>>
>>>>>>> I'm verifying BCM4335 WiFi module on i.MX6SL EVK board.
>>>>>>> The kernel i ran is latest from:
>>>>>>> git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless.git
>>>>>>>
>>>>>>> The firmware is used is from:
>>>>>>>
>>>>>>>
>>>>>>> git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
>>>>>>>
>>>>>>> NVRAM file is got from the vendor which should work for the module.
>>>>>>>
>>>>>>> But i ran into the following issues, hope somebody can give me some
>>>>>>> hints.
>>>>>>>
>>>>>>> First, i met error when module is auto loaded, but seems the driver
>>>>>>> is
>>>>>>> still loaded successfully since i found the new WiFi interface with
>>>>>>> ifconfig.
>>>>>>> But it can not work after run rfkill unblock wlan and a lot error
>>>>>>> messages comes out.
>>>>>>>
>>>>>>> I'm wondering if this driver can support bcm4335 well, can anybody
>>>>>>> provide some help?
>>>>>>
>>>>>>
>>>>>>
>>>>>>
>>>>>> I can try. I have used the bcm4335 with a SDIO3.0 controller on a x86

>>>>>> Looking at an issue right now, but your log does not show that so you

>>>>>>
>>>>>
>>>>> Thanks for the help.
>>>>> So that means the brcmfmac driver should support bcm4335 module well,
>>>>> right?
>>>>> The difference is that i'm using a ARM platform.
>>>>> Below is log with 'debug=0x146'.
>>>>> It only includes driver probe log.

Nothing exciting there either. Let's take a step back. The rfkill seems 
an issue, but I first would like to know if you can get connectivity. 
Does the 'ifconfig wlan0 up' complete at all and is it successful.

As you noticed during the up sequence there is a timeout. I would like 
to know what command that is. Could you run it again with debug=1546?

One more question. I looked up the board you mentioined. What I found 
has a dedicated SDIO slot for Wifi. Are you using that and do you know 
if that is an SDIO3.0 or not? Earlier in the thread i found this logging:

 > root@imx6slevk:~# mmc0: queuing unknown CIS tuple 0x91 (3 bytes)
 > mmc0: new high speed SDIO card at address 0001

I think it means it is a SDIO2, but I like to be sure.
