Part Number: AWR2944

Hello all,

I hope all is good, we are resetting the R5 core by using 2 APIs in the following sequence:

SOC_rcmR5PowerOnReset();

SOC_rcmR5TriggerReset();

now we have started to use the DSP core but we don't know how to control the DSP resetting from the R5 core, we have used this API:

SOC_rcmDspPowerOnReset(); before the above two APIs, but nothing changed, the DSP core is powered on and not halted.

What should be done here?

Thanks,

Hello Mahmoud,

It is not possible to reset the DSP via a register you can power it down, the same sequence for the same you can find in the power measurement demo present in the SDK 4.4.1.2.
For more details you can refer to the technical reference manual as well.

Hello Saswat Kumar,

I have checked there and found nothing can you please give the exact demo name or path to which you are referring in the SDK?

Thanks,

Also, where can this be found: DSS_DSP_PDC_INT, no ISR is named like this in the documentation.

You can go through the document for it as well, for more understanding.
