Tool/software: Linux

Hi,

Target : DRA7xx Jacinto 6 EVM running on Android O.

we are seeing WiFi driver crash often (around even 2 minutes).

Wifi is started on boot up.

we verified wlcore is loaded and wlan0 is up and we are able to discover J6 upon issuing 'p2p_listen' command in wpa_cli.

But Wifi driver crashes often with following crash log

Crash log is as follows,

    wlcore: Hardware recovery in progress. FW ver: Rev 8.9.0.0.48

     

    Can you try updating your firmware file "wl18xx-fw-4.bin" to the latest?:

    Shout be version 8.9.0.0.78.

    The one you have may not match the kernel you are using and is in any case obsolete.

    BR,

    Hi Eyal,

    Thanks for your reply.
    we have updated the firmware suggested by you.

    But it didn't solve the issue. we are facing two issues,

    1. Not receiving P2P events properly.

    2. wlcore crash - restart

    In addition to that, sometimes J6 goes to hang state with following log

    Hi,

    Based on this error that is seen multiple times:

    [ 381.911351] wlcore: Scan completed due to error.

     

    It may indicate that you are not able to get reliable responses from the firmware (gpio based interrupt from the wlan_irq pin)

    Are you sure that you are configuring the wlan_irq pin correctly in you .dts file?

    Is this a standard J6-EVM or a custom hardware based on it's design?

     

    If you can use the console to perform manual scan's (not through the Android GUI) I suggest trying this and see what happens.

     

    Best Regards,

    Eyal
