AWR2944: Changing the number of HWA&EDMA processes will affect the successful entry of the EDMA callback function

Part Number: AWR2944

Hi，TI，

  • I found a phenomenon ：I only do HWA shuffle，only do ping processing，and only one loop。when i change the number of processing，

  • Some scenarios will not be able to access the edma callback function，but the data has been moved correctly。

    Hi Carl,

    • Is it possible for you to quantize these missed callbacks a little better?
    • Are you using EDMA in polling or interrupt mode? When using polling mode, you would need to make sure that the status bit does not get cleared by the time the callback processing is done.
    • Are you using our processing chain in the SDK demo or your own customer code? If it's our demo, can you mention the SDK version?

    Regards,
