Linux/WILINK-BT_WIFI-WIRELESS_TOOLS: Could any guy here help me interpret wl12xx firmware log: fwlog

Part Number: WILINK-BT_WIFI-WIRELESS_TOOLS

Tool/software: Linux

Hi,

We have a problem in wl1271 on Linux. Sometimes its firmware will crash. And I have gotten the firmware log: /sys/devices/platform/sdhci-esdhc-imx.1/mmc_host/mmc2/mmc2:0001/mmc2:0001:2/wl12xx/fwlog.

Could some guys kindly help me to parse this log fwlog1.tar.gz?

My wl1271 driver info is as following:

wl12xx: driver version: ol_R5.SP7.01
wl12xx: compilation time: Wed Mar 22 17:58:55 2017
wl12xx: Beacon threshold set to 12
wl12xx: BSS timeout set to 400
add wake up source irq 107
wl12xx: loaded
wl12xx: state: 0
wl12xx: firmware booted (Rev 6.3.10.0.141)

If you need more information about my issue, tell me.

Thanks and Best regards,

Vito Kang

    Hi , We do not support WL12xx anymore . It is discontinued version of WiLink family. We suggest you use WiLink8

    This wifi issue I encountered is really rough. Following is the dmesg:

    There are too many "ERROR exceeded max RX BA sessions" (printed every several seconds or several minutes).
    But what I am concerned with is "wl12xx: ERROR watchdog interrupt received! starting recovery."(appeared occasionally).

    I have no idea to know what happened. Have traced several days. found there is a fwlog that maybe tell me why.

    So, looking forward to our WiFi expert. :)

    Thanks Saurabh, but this is already a commercial production. We found this bug in field. If you could interpret the fwlog file for me, I would really appreciate that.

    Best regards,

    Hi, Saurabh,

    The wl12xx firmware crash is so hard to capture, my only hope is in fwlog. Could you help me to parse it?

    Thanks,

    Vito
