Does the 6446 support the gpio interrupt on the DSP side?

Excuse me, I want use the gpio interrupt on the DSP side, and my platform is 6446.

But I found in the datasheet that there is no envent indicate gpio interrupt in DSP side, only in ARM side.

So I wonder if 6446 supports the gpio interrupt on DSP side and where can I find any demo of it?

Thank you!

    Hi,

    Yes, you can. It is supported. When we first came out with the device we did not claim the support for it which is the reason that you are observing that.

    Since lots of customers have extended their interest, we have verified the operation and now claim the support for it.

    I think you are correct that the DSP Interrupt Event is not present in the data sheet. However, the GPIO User's Guide section 2.7 has them listed. We will include those event numbers on the next release.

    Thank you for bringing this to our attention.

    Best regards, Zegeye

    Hi:

       Thanks for your answer. For I have use another production of dual-core: omapl137. And I download the csl_lib from ti web, and the file contains the gpio interrupt demo.  So I would like to know where could I down load GPIO User's Guide section 2.7 or any demo using gpio interrupt, as well as when the next release comes out?

       Thanks for your help!

       Best regards, showming

    Hi,

    You can download the doc from the product folder located at the external web:

    http://focus.ti.com/docs/prod/folders/print/tms320dm6446.html

    I am not aware if a CSL for this device exists. The DSP core used for OMAP L137 and this device are most likely the same, if not identical. So, part of the CSL code might work. I am not sure. However, if you have already used other part of the DSP and have a working interrupt the interrupt handling from the DSP perspective is the same.

    Best regards, Zegeye
