WL1835mod with kernel 3.2 wl12xx_sdio unkown symbol

Patrick Loef1

Other Parts Discussed in Thread: AM3352, WL1271

Hello,

I have a custom made board with a AM3352 and with a Linux kernel 3.2.21 with an arago filesystem.

Know I have connected the WL183mod on the MMC1 port and followed WL18xx Platform Intergrated Guide to config my board file and my .config file for the kernel. I followed the WL18xx System Build Scripts wiki.

After installing the modules to my filesystem and starting the Linux, I get the follwing errors:

    Hi Patrick,

    On the WiLink8, you don't need the wl12xx_sdio module to be inserted. Following are the required modules (in order): cfg80211.ko, mac80211.ko, wlcore.ko, wl18xx.ko, wlcore_sdio.ko

    Regards,
    Gigi Joseph.

    I see WLAN0 is present, then I will bring the wlan0 up, but then the follwing error occured:

    Hi Patrick,

    [ 217.386624] wl1271_sdio mmc1:0001:2: sdio read failed (-84)
    suggests some hardware issue on the SDIO itself.

    Regards,
    Gigi Joseph.

    Hello Gigi,

    Thanks for the reply, but what kind of hardware issue could this be?

    Because when installed the driver and run the wlconf-mimo.sh script I did get the error that wl1271_sdio could not write (-100),  and no hw could be read. After changing the sdio speed(I found a tip on the forum here) and running the script again, this problem was solved.

    Regards

    Patrick
