The Issue to port Wl18xx R8.5 driver to OMAP4470(4AJ.2.5P2)

Hi TI,

My board is based on Android4.2.2(4AJ.2.5P2 OMAP4). Now I already ported the WL18xx R8.5 drivers to my board. But it seems libhardware_legacy have some problems to support the new wifi driver. Is it related to libnl? But in Blazetablet board, I can't find the libnl* file. 

If I use the old driver, there has no libnl* file too. But there is no the errors below. Could you kindly show me what should me to port or change?

    Hi TI,

    The driver is already loaded, but why the wlan0 is not found? If I insmod wlcore_sdio.ko, the wlan0 is ready.

    Hi,

    We don't have an R8.5 version on Android. The latest is: R8.4. Please see: www.omappedia.com/.../6AK.1.2_Release_Notes for more details.

    But, wlcore_sdio is required to be inserted for wlan0 to be created. This needs to be added in the init.rc.

    Regards,
    Gigi Joseph.

    What cause the error "<6>[ 194.744293] wlan0: deauthenticating from c4:04:15:1b:c8:94 by local choice (Reason: 1=UNSPECIFIED)"?
    It can scan APs and try to connect AP, but it can't connect to AP, as the above error. Could you help me?

    Hi Joseph,

    The WPA got errors. And why set PTK failed? What conf for Wpa for me to use?

    Hi,

    Can you advise which supplicant you are using (and how was it built)? Please use the supplicant that comes as part of the official release.

    Regards,
    Gigi Joseph.

    Hi Joseph,

    The supplicant comes as part of 4AJ.2.5P2 OMAP4. Does it have problem? It works well with the old drivers.

    Thanks,
    Wei

    Lastly, I enable "CCM" in Kernel. Then It works.
