Unable to bring up the wl1271 interface the second time

Hi,

We have ported the TI WL1271 driver to the i.MX51 platform and are using it with Android. We can enable and disable the Wi-Fi interface for the first time. On trying to enable the wlan interface for the 2nd time it gives the following error log:

--- start log ---

--- end log ---

We are unable to communicate with the device after this.

We have tried this on 2 platforms:
1. BeagleBoard-xM with Linux 2.6.37 and above
2. i.MX51 Android Tablet Platform with Linux 2.6.35

In both cases we have the same issue.

This failure is seen either when doing

{

"ifconfig wlan0 up", "ifconfig wlan0 down", "ifconfig wlan0 up"

}

{

rmmod wl1271_sdio; rmmod wl1271

insmod wl1271.ko

insmod wl1271_sdio.ko

}

We have tried disabling WLAN_EN between the down and the up of the interface and the unload and load of the driver but it does not seem to make any difference.

Could someone please help in resolving this issue.

Thank you

Divya,

This seems to be SDIO issue. Please upload the complete log - with commands and output. Thanks,

-Saurabh

Hi Divya,

have you verified that the WLAN_EN signal is actually disabled and enabled correctly?

please verify that signal with oscilloscope and not only logs since without disabilng the WLAN_EN signal between “ifconfig wlan0 down” and then “ifconfig wlan0 up”, it will be the exact behavior as you see.

Regards,

Eyal

Hi Eyal,

Thanks for the reply.

We made sure that WLAN_EN pin goes LOW and HIGH between interface down and up. At the end of the post ,contains the detailed log messages for the sequence we followed.

Sequence:

========

ifconfig wlan0 down

WLAN_EN = 0 #verified in the scope that WLAN_EN is zero

WLAN_EN = 1 # verified in the scope that WLAN_EN is HIGH

#ifconfig WLAN0 up

Note that WL1271 is directly connected to iMX MMC1 interface, so there is no option for us to disconnect and connect the module. Here SDIO initialization sequence doesn't happen when we enable the interface for the second time.

Is SDIO initialization required (work done in the mmc_rescan function) when the interface is enabled for the second time ?

Regards,

Divya

Hi All,

I have attached two files FYI which contains detailed log messages(debug_level enabled) .

The below file provides the log messages when interacting with the WLAN module through Android GUI.

4403.wlan-debug-GUI.txt

The below file provides the log messages when interacting with the WLAN module through command mode.

Hi All,

       We ported the Wl1271 driver to the AM3703 platform.
       We are also using it with Android.
       We are facing the same issue as mentioned above. i.e We can enable and disable the Wi-Fi interface for the first time only.
       The second time enabling is resulting in error.

       Please find the error logs

Sandeep,

Based on the error:

omap_hsmmc omap_hsmmc.1: could not set regulator OCR (-22)

It looks like your wlan disable/enable function is not working correctly and the wlan chip is probably not being reset when you do a down/up of the interface.

This is why the driver fail to load on the second time as the firmware was not really reset. Did you verify that the enable line is actually toggling?

Please refer to the following link:

http://processors.wiki.ti.com/index.php/OMAP_Wireless_Connectivity_Hardware_Porting_for_AM37x_Platform

refer to the "Power Control and Platform Data Initialization" section and make sure your board file has a similar intialization.

In case you are doing the same and still have issues, it is possible that the fixed volatage reulator in your kernel is not working correctly (which kernel version are you using?).

You can also refer to the following link:

http://processors.wiki.ti.com/index.php/OMAP_Wireless_Connectivity_Hardware_Porting_for_new_Platform

and refer to the "Power Control – without voltage regulator" section for an alternate method of power control.

Best Regards,

Eyal Reizer

Hi Eyal,

What is the expected behavior of the WL1271 firmware after performing a WLAN_EN Disable and WLAN_EN Enable? Does the firmware have to be downloaded again or is the firmware ready to accept wireless commands and communication.

Regards

Ian

the firmware needs to be reloaded after power down

Does the firmware have to be reloaded even if we do not power down the chip but just disable WLAN_EN and then re-enable it?

Hi,

Yes, after disabling the WLAN_EN signal, the firmware has to be reloaded.

Hi Eyal,

Is SDIO initialization required (work done in the mmc_rescan function) when the interface is enabled for the second time ?

Thank you

Hi,

Yes you need to intialize the SDIO on every WLAN enable.
It's of course a system configuratio, but in our refernce design we turn off the SDIO bus when we turn off the WLAN.

Thanks,
Alon.S

Hi Alon,

We are having the exact issue as described above. In our design VBAT and VIO are hardware wired and can't be powered down. As such we cannot power down the chip but instead simply toggle WL_EN low on power down and toggle WL_EN high on power up. We experience SDIO timeouts (-110). I see in your previous posts that you turn off the SDIO bus. Is there a way to turn off the SDIO without invoking MMC/SDIO power management and voltage regulation. We do not have our board startup configure PM/regulators because the chip's power (VIO,VBAT) are hardwired to the PCB.
