TMS570LS3137: FreeRTOS not using RTI driver

rob philip

Part Number: TMS570LS3137
Other Parts Discussed in Thread: HALCOGEN

I found myself wanting to use the RTI driver to program/access the 2nd freerunning counter while letting FreeRTOS use the first one. A little digging and I notice that HalCodeGen is configured *not* to generate the RTI driver if FreeRTOS is being used, and FreeRTOS directly configures the RTI.

Is there a reason for this? Ideally FreeRTOS should force the generation of the RTI drive and use it. But maybe I'm missing something.

Hi Rob,

The HALCoGen only enabled 1 RTI compare for freeRTOS.

You can add other RTI compares to prvSetupTimerInterrupt() function.

prvSetupTimerInterrupt() is in os_port.c

Thanks.

I guess my question was why you're not using the RTI driver that HCG will generate? I haven't looked closely, but it seems like it should do what we want - and then it's available for anyone else to use as well..

Also, on a slightly different note, FreeRTOS is at release 10.1.0 but it's not clear what HCG is using, or how to update it.

Could you perhaps write up the process so I can be sure I'm using the latest FreeRTOS?

Hello Rob,

Checked with HalCoGen developer that we don't have plan to port the latest FreeRTOS to HalCoGen. The freertos used by HalCoGen is 8.2.freertos.

I don't have the procedure to port new freertos to our device. HALCoGen provides a link to freeRTOS quck start guide:
