Part Number: WL1835MOD


Tool/software: Linux

Dear Ti Community,

I am now working with AM335x and WL1835MOD. My application need to synchronize all STAs in a infrastructure network (sync by TSF in beacon of Access Point).

I have find out that TI has a thread for WL18xx Clock Synchronisation with NTP:

processors.wiki.ti.com/.../WL18xx_Clock_Synchronisation_with_NTP

processors.wiki.ti.com/.../WL18xx_Clock_Synchronisation_with_NTP_in_SDK3

I understood that for synchronize 2 H/W AM335x & WL1835MOD. I need to create some modification as applying some patches to modify Wilink Driver R8.7 and NTP

But currently, the link for package patches of Wilink Driver R8.7 and NTP has been disabled. Could you please help to tell me, where can i find out these patches?

or How can i continue to do my application without patches?

Thank you very much!

    Hi
    Please refer to following software patch that was applied temporarily to test time sync feature:
    git.ti.com/.../4a10364537b4798fde51afc7f28026d58a017e71

    This GPIO is asserted from Host periodically to request TSF from WiLink8

    Thanks

    Hi,
    The server where these patches were uploaded seems to have been decommissioned .
    I am not able to find backup of these patches . I will keep checking and if I find patches I will let you know.

    Thanks
    Saurabh
