    Hi,

    The timer test example is under pdk_am57xx_1_0_x\packages\ti\csl\example\timer, it is bare metal. In RTOS, the timer may be integrated into some driver for functionality, but not separate RTOS examples.

    Attached is a standalone one we used on A15, the timer is setup in the .cfg file:

    var Timer = xdc.useModule('ti.sysbios.timers.dmtimer.Timer');

    var IntXbar = xdc.useModule('ti.sysbios.family.shared.vayu.IntXbar');

    var TimerSupport = xdc.useModule('ti.sysbios.family.shared.vayu.TimerSupport');

    TimerSupport.availMask = 0xF0FF;

    var timer0Params = new Timer.Params();

    timer0Params.instance.name = "timerTest";

    timer0Params.period = 100000;

    timer0Params.extFreq.lo = 20000000;

    timer0Params.periodType = xdc.module("ti.sysbios.interfaces.ITimer").PeriodType_MICROSECS;

    Program.global.timerOwn = Timer.create(5, "&TimerFunction", timer0Params); // ok

    You can use the same for DSP or IPU.

    Regards, Eric
