USB superspeed peripherals Forum Discussions

What should be the expected maximum sustained throughput via a USB3 5Gbps connection when using the FX3 device as a video endpoint?  We would connect the FX3 to an FPGA, and the FPGA could feed the FX3 the maximum of 32 bits @ 100 MHz (3.2 Gbps).   

In other words, can the FX3 and the USB3 bus be configured to actually keep up with a 3.2 Gbps transfer rate for streaming video across USB3?   If not, what should be our design goal for maximum sustained video transfer? 

Hi,

I'm using C# streamer code to catch all the status of the stream,

Just like the status that the streamer present in the UI (picture below).

But I there is a different when I config the FX3 for low packet size,

In the C# streamer there is "0" in the " Transfer Rate (KBps) "

But In the C++ there is a "60"  in the " Transfer Rate (KBps) "

I'm using the code on the next location,

C# -- C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\application\c_sharp\streamer

C++ -- C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\application\cpp\streamer 

Can you direct me to the main different in the code that make the different in the "KBps"?

And maybe explain how it works?

(on the right C#, on the Left C++)

Thanks,

EliW.

Dear sir,

I want to use GPIF 32bit bus width in my design and UART for debug, spi flash for booting. but it seems that SPI flash memory signals can not be mapped because they are shared with UART_RX and UART_TX when 32bit gpif is used.

How to deal with this case: 32bit width gpif,uart debug and spi flash booting are working at the same time?

Hi,

I have picked up a task to re-spin a design using the CYUSB3014, completed several years ago.  All the people involved in the original design have since left the company.

I've looked at the firmware and tried to compile it using the latest SDK.  I get two linker errors.

I can't many mentions of these calls anywhere in the documentation supplied with the SDK or online.  I assume the API has moved on, though I can't find a note of their deprecation either.

The two calls are :

CyFx3SetCpuFreq(uint32)
CyU3PUsb2Resume()

I can find one mention of the CyU3PUsbResume function in the "EZ-USB FX3 SDK Troubleshooting Guide, V1.3.4" but sadly it does not say what library it exists in or where it is defined.

Is there an older SDK I should be using or are there new ways to achieve the same function?

Hi,

I would like to use the CYUSB3KIT-003 board.

The  CYUSB301X datasheet defined that GPIF II can operate at 100MHz at 32bit data bus.

When I look on the CYUSB3KIT-003 layout file I can see a big stub between connector J6 and SRAM memory U5.

Does the 32 bit GPIF II bus can operate at 100MHz with that stub when the CYUSB3KIT-003 connected to FPGA (signals goes from U2 to J6 and than to the FPGA and the trace between J6 and U5 is big stub)?

Did you worked at this mode?

What is the usage of the SRAM (U5) on the board? Is it for easy way to test transactions from PC to memory?

I want to pass the FX3 Compliance Test. There is a statement in the KBA at the URL below that "cyfxbulksrcsink" should be used, so I am trying to use it.

I want to enter Loopback Mode by checking the Jitter Tolerance of RX. What should I do? Do you have a sample FW?

Thanks,

Hello,

I am trying to experiment with the examples in AN65974 to buffer my FPGA board using FX3. However, I did not find the links to project files (firmware images and Verilog designs)  by any chance. Would someone kindly point where to download it?

Thank you.

Hi,

We are developing a USB3.0 camera with FX3(CYUSB3014), the camera consist of one image sensor, one FPGA and one FX3. The camera works well on several host PC we have when using 1m usb3.0 cable, and no frame loss, but when we using 2m usb3.0 cable, on a host PC, only several images can be received first, then the host cannot receive any image, we change the 2m cable to 1m cable, on the same PC, the camera works correctly, furthermore, we change to another host PC with the same 2m usb3.0 cable and the camera, the camera works correctly too. So I have some questions:

1, When use 2m cable, for FX3, what is the different with using 1m cable?

2, Could it be a software issue?
