WL1273 LSR: watchdog interrupt recovery

Gunter Schmer

Hi all,

a customer is seeing a difference in firmware behavior, that shows itself in the occurence of a watchdog based recovery. They are using two different firmwares with the same driver release.

They are using FW Rev 6.3.10.0.133, driver R5_SP3_06

which shows this trace

[10028.255157] wl12xx: firmware booted (Rev 6.3.10.0.133)

[10028.260650] wl12xx: Driver version: R5_SP3_06

[10032.885955] ieee80211 phy0: Hardware restart was requested

 

However if they drop in FW Rev 6.3.10.0.139 , the recovery goes away.

 

Could you explain the firmware behavior difference?

 

Thanks,

--Gunter

    Hi Gunter,

    I would need a fw log to understand what is happening inside the fw. Is it possible to share?
    In any case, ol_R5.SP3.06 is a very very old release. They should upgrade to the latest release (ol_R5.SP7.01)

    Regards,
    Gigi Joseph.

    About upgdaring to SP7.01, is there a compat-wireless -style release package for the drivers & stack or is only released here https://github.com/TI-OpenLink/wl12xx/tree/ol_R5.SP7.01 ?

    For older releases (such as http://processors.wiki.ti.com/index.php/Wireless_Connectivity_release_notes_Post_AMSDK05.05.00.00) there were also compat-wireless tarballs.

    Yes, everything is available for this release (same tag: ol_R5.SP7.01).
    The build script should assist you: https://github.com/TI-ECS/build-utilites/blob/master/wl12xx_build.sh
