Hello

I´ve experienced problems with burstsize > 8 when setting up a bulk endoint at the fx3.

Using code like:

        endPointConfig.enable = 1;

        endPointConfig.epType = CY_U3P_USB_EP_BULK;

        endPointConfig.burstLen = 16;

        endPointConfig.streams = 0;

        /* Configure the Endpoint */

        apiRetStatus = CyU3PSetEpConfig(CY_FX_EP_PRODUCER,&endPointConfig);

        if (apiRetStatus != CY_U3P_SUCCESS)

        {

            /* Error Handling */

            CyU3PDebugPrint (4, "USB Set Endpoint config failed, Error Code = %d\n",apiRetStatus);

        }

One update

it looks like i can go up to 

endPointConfig.burstLen = 15;

whitout getting an error ??

Does that mean burstLen = 15 means a burst of 16 ???

regards

usbstream

Yes, like the descriptor value the value is burst length -1 there. 0 is for 1 packet per burst.

Thanks.

That instresting because at least at the  example cyfxbulklpmanual there is a descritor-setting for burst of 0 and a burstlen-setting of the endpoint of 1.  This pushed me the wrong direction....
