TDA3: Use POSIX APIs in Processor SDK for VISION

Part Number: TDA3

Hi,

I have implemented a new use case for my application in Processor SDK for VISION. It is working fine.

Now I want to add pthread APIs in my use case. But I could not find any .cfg file for adding support for SYS/BIOS(xdc.useModule(‘ti.sysbios.posix.Settings’)) as mentioned in the link: processors.wiki.ti.com/.../BIOS_POSIX_Thread_(pthread)_Support

I have implemented those APIs, included header file <ti/sysbios/posix/pthread.h>. But I'm getting an error for pthread APIs such as "unresolved symbols remain".

How can I add support for SYS/BIOS POSIX thread in Processor SDK for VISION?

    Hi,

    POSIX support was validated only on A15 when OPENCV was introduced in VSDK.(Please check release notes for exact release version)
    Since then its not validated.

    Add below lines in vision_sdk\links_fw\src\rtos\bios_app_common\tda2xx\a15_0\a15_0.cfg file

    var Settings = xdc.useModule('ti.sysbios.posix.Settings');
    Settings.supportsMutexPriority = true;

    Regards,
