Tool/software: TI-RTOS

Hi TI,

beaglebone black, ccs 7.4, processor SDK RTOS 4.0.2.9

Tried to migrate from StarterWare to TI-RTOS, but cannot find DMTimer example in TI-RTOS.

StarterWare has functions such as DMTimerCounterSet(), DMTimerCounterGet(), etc...

and I configured the DMTimer in one-shot mode by,
DMTimerModeConfigure(DMTIMER_INSTANCE, DMTIMER_ONESHOT_NOCMP_ENABLE);

I am wondering whether TI expert would be able to provide DMTimer example project for my reference.

Thanks in advance

Mike,
Undfortunately, we don't have a ported Starterware example for DMTimer.
However, did you take a look at the timer example in the DIAG directory of the PDK
C:\ti\pdk_am335x_1_0_10\packages\ti\board\diag\timer

I'm thinking that you may be able to use the timer APIs in those examples. The DIAG seems to be configured for autoreload.

Hi Lalindra Jayatilleke,

Unable to make "DIAG directory of the PDK" work, however, found alternative /pdk_am335x_1_0_9/packages/ti/csl/src/ip/timer/V1/priv/timer.c, which is exactly same as StarterWare DMTimer.

Implemented DMTimer2ModuleClkConfig(), TIMERCounterSet(), TIMERCounterGet(), TIMERModeConfigure(), TIMERIntEnable(), TIMEREnable(), then everything back to StarterWare procedure.

Best

Mike
