USB Superspeed Peripherals

Hi Everybody.

   

I lost my post, so i repost this question.

   

 

   

I'm using FX3 and GPIO Slave FIFO Interface with FPGA.

   

BulkOut Endpoint somtimes fail to XferData.

   

I used medify SlaveFIFO Application firmware.

   

( When I use USBBulkSourceSink firmware, XferData working good. )

   

 

   

XferData return value is false.

   

UsbdStatus=0xc0000011, UsbdStatus=0xc000009d

   

 

   

If an error occurs, the USB is look list reenumuration.

   

 

   

========================This is UART Log Message========================

   

About to connect to USB host

========================GPIO Error Callback Function========================

   

void appGpifErrorCallback(CyU3PPibIntrType cbType, uint16_t cbArg)

   

{

   

 

   

if (cbType == CYU3P_PIB_INTR_ERROR)

   

{

   

switch (CYU3P_GET_PIB_ERROR_TYPE(cbArg))

   

{

   

case CYU3P_PIB_ERR_THR0_WR_OVERRUN:

   

zDebugPrintf(4, "CYU3P_PIB_ERR_THR0_WR_OVERRUN\r\n ");

   

break;

   

case CYU3P_PIB_ERR_THR1_WR_OVERRUN:

   

zDebugPrintf(4, "CYU3P_PIB_ERR_THR1_WR_OVERRUN\r\n");

   

break;

   

case CYU3P_PIB_ERR_THR2_WR_OVERRUN:

   

zDebugPrintf(4, "CYU3P_PIB_ERR_THR2_WR_OVERRUN\r\n");

   

break;

   

case CYU3P_PIB_ERR_THR3_WR_OVERRUN:

   

zDebugPrintf(4, "CYU3P_PIB_ERR_THR3_WR_OVERRUN\r\n");

   

break;

   

 

   

case CYU3P_PIB_ERR_THR0_RD_UNDERRUN:

   

zDebugPrintf(4, "CYU3P_PIB_ERR_THR0_RD_UNDERRUN\r\n");

   

break;

   

case CYU3P_PIB_ERR_THR1_RD_UNDERRUN:

   

zDebugPrintf(4, "CYU3P_PIB_ERR_THR1_RD_UNDERRUN\r\n");

   

break;

   

case CYU3P_PIB_ERR_THR2_RD_UNDERRUN:

   

zDebugPrintf(4, "CYU3P_PIB_ERR_THR2_RD_UNDERRUN\r\n");

   

break;

   

case CYU3P_PIB_ERR_THR3_RD_UNDERRUN:

   

zDebugPrintf(4, "CYU3P_PIB_ERR_THR3_RD_UNDERRUN\r\n");

   

break;

   

 

   

default:

   

zDebugPrintf(4, "No Error :%d(%x)\r\n ", CYU3P_GET_PIB_ERROR_TYPE(cbArg), CYU3P_GET_PIB_ERROR_TYPE(cbArg));

   

break;

   

}

   

}

   

}

   

 

   

Please Let's me know how to debug this problem?

   

 

   

Best Regards.

   

Thanks all.
