Hi,

I'm using FX3 board to thansfer data from my FPGA board. everything is OK when transfer data lenghth is less than 32MB.

When thansfer size is more than 32MB, the  xferData function  did nothing and returned a lenghth 0 immediately.

I need continously transfer acquired data in and some times may be several GB

the time out is set to infinite.

there is no limit in FX2.

anyone can help.

Thanks

Hi all,

In my design, I am sending continous data to FX3 without any clock. Whatever data comes to fx3, it will send to the PC.  How should I configure the FX3 chip to read the data correctly? 

I am generating 8 bit parallel data at 25Mhz externally and sending it through gpif. Is there any similar example design available? . Please note that I am not using any clock in the gpif design.

Thank you.

In the Master/Slave examples, change CY_FX_DMA_SIZE_MULTIPLIER from 2 to 1, and send 1KB packet to master, then slave will receive 1KB packet then zero length short packet, why?

CY_FX_DMA_SIZE_MULTIPLIER

With the Master/Slave example in AN87216, after incresing CY_FX_EP_BURST_LENGTH from 1 to 4 or 8 and loading the firmware to RAM, CYUSB3KIT-003 enumerate successfully but won't show up in Control center. Modify CY_FX_DMA_BUF_COUNT from 16 to 32 or 64 at the same time have the same problem.

How to modify CY_FX_EP_BURST_LENGTH / CY_FX_DMA_SIZE_MULTIPLIER / CY_FX_DMA_BUF_COUNT at the same time to increase the bandwidth of Master/Slave example? GPIF designed may need to be modified too according to a former post - quote

"On changing the DMA buffer size, the Data counter and Addr counter values also need to be modified in the state machine as well as in the firmware. The counter value is calculated  (counter value ) = (DMA buffersize)/ (GPIF bus width in bytes) + 1"

Hello,

I want to use the sample code provided by Cypress for using SPI Interface to read from and write to the SPI Slave but after falshing the image to the FX3 Dev Board and Capturing the signals(MOSI, SSN, SCK) can be seen, that the interface sends too much data over MOSI pin which could not be related to the data that I wanted to send to the slave(see the attached screenshot).

I Think I do a failure somewhere but I'm not sure!! would someone explane me in which order should I call the following methods, Because I could not find any documentation about the methods and regarding the parameters passing to the methods:

CyU3PReturnStatus_t CyFxSpiTransfer (uint16_t  pageAddress, uint16_t  byteCount, uint8_t  *buffer, CyBool_t  isRead);
CyU3PReturnStatus_t CyFxSpiWaitForStatus (void);
static CyU3PReturnStatus_t CyFxSpiEraseSector (CyBool_t  isErase, uint8_t   sector, uint8_t  *wip);

And should I modify the code as well !?

Kind Regards

void

CyFxBulkLpDmaCallback (

        CyU3PDmaChannel   *chHandle, /* Handle to the DMA channel. */

        CyU3PDmaCbType_t  type,      /* Callback type.             */

        CyU3PDmaCBInput_t *input)    /* Callback status.           */

{

    if (type == CY_U3P_DMA_CB_PROD_EVENT)

    {

    CyU3PDebugPrint(4,"PROD_EVENT\n");

    }

    if (type == CY_U3P_DMA_CB_CONS_EVENT)

    {

    CyU3PDebugPrint(4,"CONS_EVENT\n");

    }

}

Another problem is, if use \n then the text on the next line will begin after the last text of the previous line, if use \r\n then it will alwasy scroll down.

Hello,

We are trying to configure our ar0144 sensor to stream with settings RAW10, 30ips, 1280x800 on the denebola board.

Camera input xtal is 27mhz

Mipi errors show 0, but AMCap reports no fps and no picture. Debug output:

Prod = 45 Cons = 45  Prtl_Sz = 22000 Frm_Cnt = 99 Frm_Sz = 1678720 B

0 0 0 0 0 0 0 0 0

Prod = 45 Cons = 45  Prtl_Sz = 19568 Frm_Cnt = 100 Frm_Sz = 1676288 B

0 0 0 0 0 0 0 0 0

Prod = 45 Cons = 45  Prtl_Sz = 18128 Frm_Cnt = 101 Frm_Sz = 1674848 B

0 0 0 0 0 0 0 0 0

Scope traces of mipi clk/data, Pclk, HS and VS are shown below. My project is attached.

mipi clk bottom trace, arithmetic diff:

mipi clk/data, 1=data, 2=clk

Any suggestions of what to test or try?

Thank you,

Hello

There is a PC (NEC PC-GN254U2GA) that carries both intel USB3.0 host device and ASMedia USB3.1 host device. Only when connecting a product using FX3 this time and transferring data, when connecting to ASMedia. The USB transaction error occurs.

Switching between two devices is performed on the customer's HOST GUI.　For the internal system, please refer to the PDF file after the ”EP変更後.pdf”.

Attach the analyzer log in LeCroy.

As a phenomenon, an error occurs during the operation of using a dedicated application on Windows and intermittently downloading image data of about 2MByte, and the application stops data transfer.　The error frequency occurs when tens to hundreds of image frames are transferred from the start of data transfer.

The transaction is considered to be a transaction error because the USBStatus value acquired by the application on Windows has stopped at 0xC0000011.

When an error occurs, the data transfer to FX3 is stopped because the flag on the GPIF side of FX3 becomes buffer full.　When the USB cable is inserted and removed from this state and the data transfer is started again, the data transfer starts normally.　For this reason, the circuit itself on the GPIF side is operating normally, and we have determined that this issue has occurred between FX3 and the host PC.

It seems that the  issue seems to occur only ASMedia.

Based on the attached log, the data packet is Failed.(ex. Transaction 20/Transaction 25/ Transaction 26,,etc)

Q)  Could you please tell  me the root cause based on the above situation?

Hi,

I am trying to develop code in C++ with an FX3 USB Controller.

I started with example applications included in the SDK.

Unfortunately only the applications (Streamer, Control Center) coded in C# do work, within the C++ applications I am not able to detect a connected USB device.

I tried both, just executing the .exe file as provided in the SDK and also recompiled it on my Computer. I am using Windows 10 Enterprise and Visual Studio 2017.

I tried to develop my own C++ application and found out that DeviceCount returns zero although a device is connected.

Any suggestions what could be the problem?

Thanks a lot!

Regards,

Lou

Hello Community,

Can we pass vendor requests without using control center i.e..,can we make it automatic in code itself?

Let me know whether this is possible or not.
