WL1271 can not wake up Omap4430 from suspend mode

Hi,

The first thing I would try is setting up an "any" filter:

iw phy0 wowlan enable any

Then ping / send traffic to the device and see if it wakes up.

If this doesn't work, make sure you have followed the steps found here:

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

Hi Barak,

Thanks for your information,

we have already followed the procedure :

1. iw phy0 wowlan enable any
2. echo mem > /sys/power/state
   System goes to Suspend mode.

3.Ping the IP address from PC side.

4.System does not wakeup.

and the log as like below, if I am wrong, please correct mi.

Hi,

Please make sure you have made the HW changes and SW patches mentioned here: 

http://processors.wiki.ti.com/index.php/OMAP_Wireless_Connectivity_AM335x_EVM_adding_Suspend_Resume_WOW_mode

Regards,

Barak

Hi Barak,

May I know the changed of GPIO is for Wifi IC or AM335 ?

• WLAN_IRQ: moved from GPIO3_17 to GPIO0_19 (for waking up SA from suspend on WOWLAN event)

Thanks

Hi,

The change of the GPIO is for the AM335x.

Regards,

Barak

Hi Barak,

Thanks for your information,

we have checked HW&SW setting are same as GPIO 53 for Wlan IRQ on the OMAP4430 Blaze & Panda board.

is there any other detial I missed  ?
