Hello,

In datasheet,they have mentioned as below.

Part  number                               USB        SRAM (kB)        Storage Ports           Package Type

CYUSB3035-BZXI                        3                 512                        2                       121-ball BGA

CYUSB3035-BZXC                      3                 512                        2                       121-ball BGA

CYUSB3033-BZXC                      3                 512                        1                       121-ball BGA

CYUSB3031-BZXC                      3                 256                        1                       121-ball BGA

1)CYUSB3033-BZXC and CYUSB3031-BZXC supports only one storage port.which port  is supported by these two CYUSB3033-BZXC ,CYUSB3031-BZXC?is it s0 port or s1 port?

2)CYUSB3031-BZXC is supports only 256KB.currently we are using CYUSB3035-BZXC  device with slavefifo apllication.how can i find that my application requires whether 256kb or 512kb?let me know?

thank you.

I’m a software guy who's new to USB development and would like to learn more about cypress solutions.  However,  I’m not sure which kit can help me.

If I would like to play (making Windows app by using CyAPI.h) with the firmware library shows on

https://www.cypress.com/documentation/software-and-drivers/ez-usb-fx3-software-development-kit

or the example (maybe there are pointed to the same thing I’m not sure)

https://www.cypress.com/documentation/code-examples/usb-superspeed-code-examples

Is it sufficient by purchasing CYUSB3KIT-003 sololy?  or the above examples are just examples that I have to find a way to get the other experimental board?

Is there a document to walk me through how to play all of them one by one?  Or at least one for getting me a basic start?

Our customers are considering booting an FPGA using FX3S.

In order to download FPGA configuration data from the SD card, the FX3S requires an SD card I / F and SPI(master).

Looking at the FX3S data sheet, it appears that we need to use S1-Port to configure the SD SPI.

In that case, is it necessary to select CYUSB3035 which has 2 Strage ports?

Hi, all.

I am a newman of FX3, and i using SuperSpeed Design Examples V1.2\FX3 Firmware Projects\GPIF_Example10 to set up a 8bits parallel communication with one slave mcu.

for now data send out from FX3 is ok, but i don't know how to trigger FX3 read procession.can any one help me out?

i have tried to set up the signals follow the GPIF design timing but the FX3  do not trigger a read procession.

where is the interface signal specification? i want to konw the signals timing.

and is there any files for good understanding of the GPIF state machine?

Tks

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.
