Hello

I have a stupid question.

I import example project from USBVideoclass sample from sdk.

import->general->existing project into workingspace and select copy project to the workingspace.

I just want to change the prodcut name to try first.

I modiyf "FX3 "to "AAA" then i use control center to burn into ram.

After doing that, I stll see the name "FX3" from windows device manager.

Could anyone give me a suggestion?

const uint8_t CyFxUSBProductDscr[] __attribute__ ((aligned (32))) =

{

    0x08,                           /* Descriptor Size */

    CY_U3P_USB_STRING_DESCR,        /* Device descriptor type */

    'F',0x00,

    'X',0x00,

    '3',0x00

};

I know that MIPI cameras are what are usually used with the CX3, but sometimes it is necessary

to support old-fashioned hardware, and that's where the ADV7280A-M comes in.

I am working on Cypress FX3 USB3.0.I am using EZ USB FX3 SDK/1.3/Application/cpp/Streamer.In streamer.h code ,there is one function called "Xferloop()".I collected the data of "buffer" stored in "myfile.txt".The throughput of the streamer decreased from 395MBps to 110MBps because of writing data into the myfile.I think if I write data into disk using different thread then speed could increase.How to do this? Please help.

hi there, these days i was designing the GPIFII interface of FX3. cypress company has provided four image file (streamout.img, streamout.img,loopback.img,short_zlp.img,) for learning different configuration of GPIFII.  now i want to see the source project of the streamout.img and modify some code to generate different configurantion.. And i have read the AN65974, there is not enough description of how to modify and use the source project to generate the streamout.img. besides, there is a project file (slaveFifoSync) with AN65974, i don't know if it is the source code of those four image files.

I updated SDK 1.3.3 with 1.3.4, rebuilt my project and now the .img file size generated is 132K which won't fit into our 128K eeprom. The old SDK produced a 127K file. The source code did not change. What changed?

I'm having problems in sending consecutive "CyU3PI2cSendCommand" commands.

I modified the FX3 i2c example in this way:

            case CY_FX_RQT_I2C_EEPROM_WRITE:
                status  = CyU3PUsbGetEP0Data(wLength, glEp0Buffer, NULL); // Here I receive the data
// Here I'm trying to send 4 times the same message...
                if (status == CY_U3P_SUCCESS)
                {
                    CyFxUsbI2cTransfer (wIndex, i2cAddr, wLength,
                    glEp0Buffer, CyFalse);
                }
                if (status == CY_U3P_SUCCESS)
                {
                    CyFxUsbI2cTransfer (wIndex, i2cAddr, wLength,
                    glEp0Buffer, CyFalse);
                }
                if (status == CY_U3P_SUCCESS)
                {
                    CyFxUsbI2cTransfer (wIndex, i2cAddr, wLength,
                    glEp0Buffer, CyFalse);
                }
                if (status == CY_U3P_SUCCESS)
                {
                    CyFxUsbI2cTransfer (wIndex, i2cAddr, wLength,
                    glEp0Buffer, CyFalse);
                }
                break;

Observing SDA and SCL with an oscilloscope, the weird thing is that if data has "wLength" up to 33 bytes, all transactions go fine, while if wLength is 34 or more, only the first transaction goes through.

HI， everyone，

      I had a problem and I don't know how to handle it:

      When I use Cypress 3014 platform(FX3) AN75779 project to achieve binocular camera  through USB super-speed transmission of images to the PC. The camera uses two OV9281 cameras. This is an 8-BIT camera. The original project used a 16-bit data camera.So the schematic is designed as follows.DQ0 to DQ7 and DQ8 to DQ15 are connected by different cameras.The two cameras are synchronized.

When I configure the two cameras to 480P, they work normally, so I infer that my GPIF configuration is okay, but when I configure them to 720P, “DMA Reset Event: Commit buffer failure” mistake occurred.PC can receive some data, but there is no image. It is supposed that DMA has some data commit failures,but the original project is not to transfer 720p-16bit image?  My two cameras are also 16 bit(8bit+8bit) images.I made some changes as follows. Is there anything else such as DMA configuration  that needs to be changed?

Hi,

is it possible to read the actual counter values of DATA_COUNT, ADDR_COUNT and CTRL_COUNT registers?

Thanks in advance.
