Other Parts Discussed in Thread: AM1808, WL1271, OMAPL138

Hi,

I am novice in embedded Linux, I have AM1808 board and WL1271 and what all I know is this should work as WLAN. I have a series of doubts.

1. Is there any driver which is already developed in OMAPL138 for  WL1271? If developed where can i get? Else how to start developing driver for WL1271 using SDIO interface.

2. Where exactly to include the SDIO,  WLAN and other related configuration(if any) in MENUCONFIG.

 

Thanks,

G

    Hi,

    we do have support for 1271 over OMPL138, please try ower wiki page in http://processors.wiki.ti.com/index.php/ARM_Processor_Wireless_Connectivity_Downloads

    and download SW-008 package.

    in addition for the SDIO you also need to have some switches in the .config, yo can see more information with the release itself.,

    Regards,

    I download SW-008 package, it has SDIO support according to release document. My intension is to test WLAN so I followed the instruction as per the Software development kit documentation.

    To test WLAN demo, followed this link http://processors.wiki.ti.com/index.php/AM18x_Wireless_Connectivity_Demo, Under system settings "WIFI" icon is missing, Need to install manually?.

    Tried to install but gives this following error.

    root@arago:~# /usr/share/wl1271-demos/wlan/install-wlan.sh
    Installing WL1271-WLAN kernel modules...
    sdio: version magic '2.6.33-rc4 preempt mod_unload modversions ARMv5 ' should be '2.6.33-rc4 preempt mod_unload ARMv5 '
    FATAL: Error inserting sdio (/lib/modules/2.6.33-rc4/kernel/drivers/net/wireless/wilink/sdio.ko): Invalid module format
    Failed to insert sdio.ko


     kindly,  let me know how to make this work.

    Hi Gopi K T,

    the release for OMAPL138x works with Terminal only, and GUI is not working, for that reason the WiFi icon is missing.

    As for bringing the board up, we did not see the issues that you see, however please note that the SD card to be used is one that works with 1.8V. Rather than using  3.3
