wireless with 3517evm

Trying to get the wireless to work with this board, and followed the user and porting guides.  But, I end up with a kernel panic when trying to manually bring up the interface.  The 2 docs I followed are

http://processors.wiki.ti.com/index.php/TI-Android-FroYo-DevKit-V2.2_UserGuide

and

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

 

Before going further, I should ask if this is even the correct path to take?  I just noticed code in the rowboat tree in the external directory, and have to wonder if that is what should be used. 

If the guides are the right path, the panic looks like:

    From the links you are referring to  it appears that you are attempting to run android Froyo version with kernel 2.6.32.

    The wlan wilink driver supplied with this devkit release does not support am3517evm. Please use the patches supplied by LogicPD to enable wlan.

     

    ALso note that from the gingerbread release (and kernel 2.6.37) onwards we do not support the wilink driver and instead use wl12xx_compat driver as documented in our Porting guide:

    Yeah, I was coming to that conclusion with Froyo.  I haven't had much luck with the LogicPD patches, and just started down the Gingerbread route.

    Moving in this direction, I don't see a direct way to build wl12xx_compat for the am3517evm.  From the porting guide, I have configured the kernel and built wpa_supplicant.  From the source tree, I can see how to build the other driver in hardware/ti/wlan, but from what I've read that isn't what I want.  Is there a recommended method for building wl12xx_compat on the am3517evm?

    Did you manage to port the changes from the LogicPD patches on the DevKit kernel?

    I think these would be about the wlan platform data, pinmuxing etc

    To compile the wl12xx_compat driver for am3517evm you can modify the top level Makefile as follows. You will need to first make the file writable first.

    To build the wlan drivers and install issue the following command from the top of DevKit sources:

    -- What patches should be taken from LogicPD?  What I have doesn't build and has a 2.6.32 kernel.

    -- Oddly enough, I did exactly what that patch does right after posting.  It ends with a cannot stat 'drivers/net/wireless/wl12xx/wl12xx.ko': No such file or directory.  it does build compat.ko, cfg80211.ko, and mac80211.ko.  It looks like it goes into ti/wlan/WL1271_compat/drivers/drivers/net/wireless/wl12xx/ and builds built-in.o and wl12xx_platform_data.o.  It's been a while since I've wading into kernel Makefiles, but I'm thinking this is a config issue. I've made sure CONFIG_CFG80211,  CONFIG_LIB80211, and CONFIG_MAC80211 are off, and hacked the Kconfig to enable CONFIG_WIRELESS_EXT and CONFIG_WEXT_*.   Any other ideas?

    Hi Nordstrand，

    Do you resolve it?

    I debug it on am3517evm, but it don't work well.I don't know how to control WLAN_EN pin. Can you give me some advices?
