Using RTI as RTC

Evgenyy

Intellectual 490 points

Other Parts Discussed in Thread: HALCOGEN

Is it possible to use RTI module to provide real-time clock (RTC) functionality in the project which also use FreeRTOS?

The main thing is that OS "vPortPreemptiveTick" interrupt links to "RTI Compare 0" interrupt assignment (as it recommended for FreeRTOS settings in HALCoGen), and OS fails to run when I'm trying to call rtiInit() function. What's the problem can it be, have anybody any suggestions?

Thanks, Evgenyy.

Evgenyy,

I have forwarded your question to the HALCoGen expert. We will get back to you as soon as possible.

Here is a post in forum talking about how to setup HALCoGen with FreeRtos, Using the FreeRTOS component from HALCoGen - TMS570 ...,

Please make sure you follow all the instructions in this post.

Thanks,

Haixiao

Evgenyy,

the FreeRTOS is not designed to work with the RTI driver.

The OS tick is tied to RTI compare 0 interrupt.

To get the RTI and FreeRTOS working together you need to modify the rtiInit function to do not disturb the compare 0 interrupt used for the OS tick.

Cheers

Marcus
