C6472 HPI interrupt from host to dsp - DSPINT. How to handle?

Yuriy Puchkov

I have C6472 communicating with FPGA via HPI interface (not booting stage). Both sides sends data vise-versa. Host side can set DSPINT bit to issue an interrupt for DSP.

How can I handle this interrupt? I can find any DSPINT- or HPI-releted event constants in CSL.

The problem is I found related event IRQ_EVT_DSPINT in csl_irq.h, but there are no csl_irq.h in latest CSL package for C6472.

There are only csl_intc.h library, but there no IRQ_EVT_DSPINT in csl_intc.h

Hi Yuriy,

Could you please tell me which code of example are you referring ?

Are you trying to boot through HPI or data transfer ?

Please refer the chapter 5 in HPI user guide for HPI interrupt.

Please refer the latest CSL API guide.

Thank you for fast reply!

It's for data transfer , but I found solution, at last! There is event 85 declared as CSL_INTC_EVENTID_HPI_INT. The problem was that I used keyword "_DSPINT" search in latest API guide.

It works perfectly with scl_intc library.

Hi Yuriy,

Sounds good.

Thanks for the update.
