HI,there.

the composite device（UVC+usb-uart  ----they are all use IADs） is work in windows，but when i use it in linux ,it just only one device can work.

dmesg | tail -20

hope someone can help me to solve my doubt.

Many thanks in advance!

hello.

I use CYUSB3014. StreamIN.

Then I connect device with PC, I see in Control Center bootloader, but I download streamin to controller, my device has lost in Control center, or connect/disconnect, or norm worked. 

The controller behaves differently with different cables. That so many are rejected cables or firmware nuance there?

Hi all,

after having updated my AN75779 based project with the help of Technical Support, that gave me Rev Q215, I was happy to see that INVALID_SEQUENCE errors disappeared; and the new frame timeout system saved some bad situation...

But my happiness ended when I discovered that the frame acquisition sometime stops suddenly and there is no way to restore it. This problem is random: may happen after few minutes or hours. From the serial debug I get no errors, it seems all right but the acquisition cannot recover; the only way is a reboot.

I already tried: CyU3PPibDeInit/CyU3PPibInit, CyU3PDmaMultiChannelDestroy/CyU3PDmaMultiChannelCreate, CyU3PUsbResetEndpointMemories, but the acquisition remains stuck or sometime only few garbage bytes are returned.

How can avoid this? Or, at least, restore the acquisition...

Thank a lot!

Dear Sir,

Can you give me some solution to isolate CX3 from HOST?(e.g. PC)?

In medical situation, some instruments need electrical isolation between USB host and USB slave.

I found USB-4630 USB3.0 hub(from advantech,taiwan) and USB204R1(from Humandata, a japanese company) are isolator device, but I want to know a low cost solution. is there IC solution for this case?

Best regards!

How to tune FX3 I2C SCL SDA timing same as MCU, FX3 I2C SDA is not alignment with falling edge SCL.

Can FX3 tune register let waveform same as MCU.png show. SDA edge is alignment with falling edge of SCL.

To whom may concern, 

Hello, we are currently developing a camera using the CX3 (cyusb3065) chip.
There are no problems to use image capture function with the viewer of the PC or smart phone.
But, it is not easy to use  this function as we press the camera button on the camera device.
We try to create a DMA channel and then, press the capture button to try to convey this message to the viewer's PC program but it is not working properly.
Please  support if you have the solution on this problem.
 
As below are some of the code being implemented.
//
 
in  CyCx3Appinit()
 
    /* Create a DMA MANUAL_IN channel for the producer socket. */
   dmaChConfig.size   = 32;
   dmaChConfig.count   = 2;  //CY_FX_BULKLP_DMA_BUF_COUNT;
   dmaChConfig.prodSckId   = CY_FX_EP_PRODUCER_SOCKET;
   dmaChConfig.consSckId   = CY_U3P_CPU_SOCKET_CONS;
   dmaChConfig.dmaMode   = CY_U3P_DMA_MODE_BYTE;
   /* No callback is required. */
   dmaChConfig.notification   = 0;
   dmaChConfig.cb    = NULL;
   dmaChConfig.prodHeader   = 0;
   dmaChConfig.prodFooter   = 0;
   dmaChConfig.consHeader   = 0;
   dmaChConfig.prodAvailCount  = 0;

   status = CyU3PDmaChannelCreate (&glChHandleStatusIn, CY_U3P_DMA_TYPE_MANUAL_IN, &dmaChConfig);
   if (status != CY_U3P_SUCCESS)
   {
    CyU3PDebugPrint (4, "\n\r>CyU3PDmaChannelCreate failed, Error code = %d", status);
 //   CyCx3AppErrorHandler(status);
   }

   /* Create a DMA MANUAL_OUT channel for the consumer socket. */
   dmaChConfig.prodSckId = (CyU3PDmaSocketId_t)CY_U3P_CPU_SOCKET_PROD; //CY_U3P_CPU_SOCKET_PROD;
   dmaChConfig.consSckId =  (CyU3PDmaSocketId_t)CY_FX_EP_CONSUMER_SOCKET; //CY_U3P_UIB_SOCKET_CONS_0;
   status = CyU3PDmaChannelCreate (&glChHandleStatusOut, CY_U3P_DMA_TYPE_MANUAL_OUT, &dmaChConfig);
   if (status != CY_U3P_SUCCESS)
   {
    CyU3PDebugPrint (4, "\n\r>CyU3PDmaChannelCreate failed, Error code = %d", status);
 //   CyCx3AppErrorHandler (status);
   }

   /* Set DMA Channel transfer size */
   status = CyU3PDmaChannelSetXfer (&glChHandleStatusIn, CY_FX_BULKLP_DMA_TX_SIZE);
   if (status != CY_U3P_SUCCESS)
   {
    CyU3PDebugPrint (4, "\n\r>CyU3PDmaChannelSetXfer  glChHandleStatusIn Failed, Error code = %d", status);
 //   CyCx3AppErrorHandler (status);
   }

   status = CyU3PDmaChannelSetXfer (&glChHandleStatusOut, CY_FX_BULKLP_DMA_TX_SIZE);
   if (status != CY_U3P_SUCCESS)
   {
    CyU3PDebugPrint (4, "\n\r>CyU3PDmaChannelSetXfer  glChHandleStatusOut Failed, Error code = %d", status);
 //   CyCx3AppErrorHandler (status);
   }

After pressing Capture Button, Function call

static void
CaptureIrqCallback (CyBool_t isButtonPressed)
{
 CyU3PDmaBuffer_t bufferToSend;
 CyU3PReturnStatus_t status = CY_U3P_SUCCESS;

 CyU3PMemSet(glStatusPacket, 0x00, 16);

 glStatusPacket[0] = 0x02;          /* bStatusType = VideoStreaming interface */
 glStatusPacket[1] = 0x01;          /* bOriginator = ID of VideoStreaming interface */
 glStatusPacket[2] = 0x00;          /* bEvent       = Button press */
 glStatusPacket[3] = isButtonPressed ? 0x01 : 0x00; /* bValue   = Button press state */

 bufferToSend.buffer = glStatusPacket;
 bufferToSend.count = 4;
 bufferToSend.size = 16;
 bufferToSend.status = 0;

 //CyU3PDebugPrint (4, "\n\r>Before Button press send");
 status = CyU3PDmaChannelSetupSendBuffer (&glChHandleStatusOut, &bufferToSend);
 if (status != CY_U3P_SUCCESS)
  CyU3PDebugPrint (4, "\n\r>SendButtonPressToHost(%d): SetupSendBuffer failed with 0x%x\n", isButtonPressed, status);
 else
  CyU3PDebugPrint (4, "\n\r>Commmand DMA channel setup, wait for completion");

 status = CyU3PDmaChannelWaitForCompletion(&glChHandleStatusOut, CYU3P_WAIT_FOREVER);
 if (status != CY_U3P_SUCCESS)
 {
  CyU3PDebugPrint (4, "\n\r>SendButtonPressToHost(%d): WaitForCompletion failed with 0x%x\n", isButtonPressed, status);
  CyU3PDmaChannelDestroy (&glChHandleStatusOut);
 }
 CyU3PDebugPrint (4, "\n\r>Capture command sent to host\n");
}

The error occurs at this point at  CaptureIrqCallback ().

status = CyU3PDmaChannelSetupSendBuffer (&glChHandleStatusOut, &bufferToSend);
 if (status != CY_U3P_SUCCESS)
  CyU3PDebugPrint (4, "\n\r>SendButtonPressToHost(%d): SetupSendBuffer failed with 0x%x\n", isButtonPressed, status);
 else
  CyU3PDebugPrint (4, "\n\r>Commmand DMA channel setup, wait for completion");

 status = CyU3PDmaChannelWaitForCompletion(&glChHandleStatusOut, CYU3P_WAIT_FOREVER);
 if (status != CY_U3P_SUCCESS)
 {
  CyU3PDebugPrint (4, "\n\r>SendButtonPressToHost(%d): WaitForCompletion failed with 0x%x\n", isButtonPressed, status);
  CyU3PDmaChannelDestroy (&glChHandleStatusOut);
 }

I have CYUSB3ACC_005 and Superspeed Explorer Kit, and ZC706. 

My requirement is to transmit 32-b UVC from FPGA and allow quick download a block of control/calibration data (10 MB+) into FPGA via USB3 when the UVC is idle. 

After some research my idea is as follows. Would like to check whether it makes sense. 

1) Change the data width in fx3_uvc.cyfx to 32-bit, add a state machine (DOWNLOAD) to do 2~5. 

2) Add a INTR_FPGA pin to interrupt the Zynq CPU when the FX3 Firmware has a sub-block of control data in EP0. 

3) FX3 Firmware moves state machine by CyU3PGpifSMStart(DOWNLOAD_START) state, wait for 1ms. 

4) Zynq CPU instructs FPGA to control READ pin and read 32-bit data. 

5) Repeat 2/4 until all 10MB data is transmitted. 

6) Move state machine to UVC by CyU3PGpifSMStart (START_SCK0, ALPHA_START_SCK0);
