WL1837 wlcore crash joining network [R8.3 SP1]

Dav01
Expert 2300 points

Please see sequence of wlcore crashes while failing to join work a network.

PHY firmware version: Rev 8.2.0.0.195
Firmware: Rev 8.8.0.0.13

Let me know how we can track down the root cause.

Thanks /David

    Hi David,

    This also looks to be from the fw side...
    Please share the complete description of the steps you performed to get to this error. I need to recreate the issue and get the fw logs...

    Also, please share the complete driver logs as well.

    Regards,
    Gigi Joseph.

    Ok, in this other scenario it gets stuck in a crash loop during 10 minutes, sometimes crash after crash after crash, sometimes 30s in between.

    This seems to be a recurrent phenomenom when trying to join a wpa2 AP, crashing before it has chance to succeed. The last line before the stack dump has several times been: wlcore: Scan completed due to error.

    Indicating that it might be crashing during a scan, and then failing the scan - and as our current logic need to see the ap in a scan before joining we will never join as long as we fail to scan.

    Anyway, more verbose dumps coming up.

    best /d
