Missing WLAN files in latest AM18x EZSDK

Martin Ambrose
Intellectual 1510 points

Hello.

I am using the latest EZSDK from here

http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/sdk/AM1x/latest/index_FDS.html

 

Looking at the documentation here

http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/sdk/AM1x/latest/exports/sitara-linuxsdk-sdg-05.02.00.00.pdf

 

I would expect to find the install-wlan.sh script on the filesystem but do not. Nor is there a wlan_cu utility. E.g.

root@am180x-evm:/usr/share/wl1271-demos# ls /usr/share/wl1271-demos/

bluetooth

Is there a new or alternate method for configuring the wl271 from the command line?
I did run the Wifi demo from the matrix gui and can scan to find my local essid.
However I wasn't able to actually connect to the network via the gui.

    Hi Martin,

     

    We have lots of material in our WiKi page that presents how to configure the WiFi and the Bluetooth, specifically for the SDK5.02

    Please visit our WiKi page in http://processors.wiki.ti.com/index.php/ARM_Processor_Open_Source_Wireless_Connectivity#Demos

     

    Regards,

    Eyal

    Hi Eyal,

     

    Thanks for the link. Do you agree that the SDK documentation is outdated in this regard? Specifically

    http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/sdk/AM1x/latest/exports/sitara-linuxsdk-sdg-05.02.00.00.pdf

     

    Is it correct that this is the best/only location for configuring station mode via the command line?

    Unfortunately that recipe doesn't work for me. In particular these two steps fail

            root@am180x-evm:~# ifconfig wlan0 down

            ifconfig: SIOCGIFFLAGS: No such device

            ...

            root@am180x-evm:~# modprobe wl12xx_sdio

            root@am180x-evm:~# calibrator plt calibrate

            Fail to set PLT power mode on

     

    I think I may have a hardware problem.

    Going back to the legacy driver (I presume) in DVSDK 4.02.00.06

    I get a kernel oops when loading the firmware

            root@arago:/etc/rc5.d# /usr/share/wl1271-demos/wlan/install-wlan.sh

    Any suggestions/ideas?
