USB Superspeed Peripherals

Hello all,

I found in CyUsb3.pdf the instructions to configure the inf file, although I don't have much experience with inf files in general. I've added my devices VIDs and PIDs, and they enumerate properly, so that's a good start.

I'm currently trying to get the script feature to download the firmware into the FX3 when it attaches. I have it in a state where it creates the registry entry that points to the script location, and I've made sure that folder exists (and it is a subdirectory of System32). If I copy the script manually, it runs and downloads the firmware when the FX3 connects, so that's excellent. The trouble is that it doesn't copy the script into that location when I install the driver.

Is it supposed to copy the script, or am I supposed to do it myself? If so, what have I missed?

While I'm on the topic, is there any way to make the INF file create the folder if it doesn't already exist, or am I on my own for that? It seemed from other answers I saw that it might not be possible to create the folder from the INF file.

I'll attach the files so you can see what I've done so far.

Hello,

During write transfer (Fx3 to PC), despite having full buffer (indicated by asserted DMA READY flag). After partial flag is asserted i keep writing 3 more data words, watermark value is 3 and I have 16-bit data bus. I used following formula from AN65974 app note: watermark x (32/bus width) –3.

In attachment I send firmware with GPIF project.

Hello,

We have been using CYUSB3014-BZXI and EZ-USB FX3 SDK 1.0 version.

The problem is it takes long time (about 250msec) in function CyU3PUartTransmitBytes.

We send 7Bytes, it takes more than 250msec. I think the time is derived from the wait time in  CyU3PUartTransmitBytes before actually sending UART.

How to improve the UART transfer  speed?

Thanks for your quick response in advance.

When I use GPIF-II sync slave fifo interface with 2-bit address mode, I can successfully set watermark values for the four threads / P-port sockets. Just like the following:

    CyU3PGpifSocketConfigure (0, CY_FX_PRODUCER_1_PPORT_SOCKET, 6, CyFalse, 1);
    CyU3PGpifSocketConfigure (1, CY_FX_PRODUCER_2_PPORT_SOCKET, 6, CyFalse, 1);
    CyU3PGpifSocketConfigure (2, CY_FX_PRODUCER_3_PPORT_SOCKET, 6, CyFalse, 1);
    CyU3PGpifSocketConfigure (3, CY_FX_CONSUMER_1_PPORT_SOCKET, 5, CyFalse, 1);

And now, I switch to 5-bit address mode for more transfer endpoints. And I want to set watermark values for each P-port sockets. Here are fourteen P-ports. However the following code is not availbale.

    CyU3PGpifSocketConfigure (0, CY_FX_PRODUCER_1_PPORT_SOCKET, 6, CyFalse, 1);
    CyU3PGpifSocketConfigure (1, CY_FX_PRODUCER_2_PPORT_SOCKET, 6, CyFalse, 1);
    CyU3PGpifSocketConfigure (2, CY_FX_PRODUCER_3_PPORT_SOCKET, 6, CyFalse, 1);
    CyU3PGpifSocketConfigure (3, CY_FX_CONSUMER_1_PPORT_SOCKET, 5, CyFalse, 1);
    CyU3PGpifSocketConfigure (0, CY_FX_CONSUMER_2_PPORT_SOCKET, 5, CyFalse, 1);
    CyU3PGpifSocketConfigure (1, CY_FX_CONSUMER_3_PPORT_SOCKET, 5, CyFalse, 1);
    CyU3PGpifSocketConfigure (2, CY_FX_PRODUCER_4_PPORT_SOCKET, 6, CyFalse, 1);
    CyU3PGpifSocketConfigure (3, CY_FX_PRODUCER_5_PPORT_SOCKET, 6, CyFalse, 1);
    CyU3PGpifSocketConfigure (0, CY_FX_PRODUCER_6_PPORT_SOCKET, 6, CyFalse, 1);
    CyU3PGpifSocketConfigure (1, CY_FX_PRODUCER_7_PPORT_SOCKET, 6, CyFalse, 1);
    CyU3PGpifSocketConfigure (2, CY_FX_CONSUMER_4_PPORT_SOCKET, 5, CyFalse, 1);
    CyU3PGpifSocketConfigure (3, CY_FX_CONSUMER_5_PPORT_SOCKET, 5, CyFalse, 1);
    CyU3PGpifSocketConfigure (0, CY_FX_CONSUMER_6_PPORT_SOCKET, 5, CyFalse, 1);
    CyU3PGpifSocketConfigure (1, CY_FX_CONSUMER_7_PPORT_SOCKET, 5, CyFalse, 1);

Then no data can be transfered through any P-ports.

So, I wonder what's the correct way to assign watermark values for P-ports - under 5-bit address mode.

Hi, I'm making code to test i2c write operation.

FX3 is sending out data to external FPGA through i2c and if FPGA receive data, turn on the led connecting FPGA.

But when I check the i2c signal on the signal analyzer program,

the i2c scl clock is stopped after sending the device address.

The device address of FPGA is 0x70.

And this is my i2c write code.

If you know what's the problem, please let me know.

Thank you.

Hello everyone,

In my current project, I am required to send 16 bits data from a FIFO inside FPGA (Cyclone  IV E) to PC through FX3.

I followed AN65974 note and ran the given example code for Stream IN Transfer, which I assume is appropriate for the application here. It seemed to work without failures on streamer GUI at 100MHz.

Since the FIFO in FPGA is being written at much slower speed, I wanted to slow down GPIF interface as well. However, when I tried slower clocks, says 50 MHz, the transfer failed. I only changed PLL on FPGA side which drives pclk.

Am I required to change anything from firmware side for the slower clock speed?

Also, since I am clearly a novice in this area, I appreciate any pointers on how I should read the FIFO inside FPGA to send data over GPIF.

Thank you very much for your time.

hi,

Last time i issue a problem is :

https://community.cypress.com/t5/USB-Superspeed-Peripherals/ubuntu-host-cypress-Isochronous-mode-can-t-open-multiple-cameras/m-p/274374

but it closed, so i create a new question for continue debug.

Since i set:

 FX3_EP_ISO_VIDEO_SS_BURST 0x07
 FX3_EP_ISO_VIDEO_SS_MULT   0x01
 FX3_UVC_ISO_PAYLOAD_SIZE = ((FX3_EP_ISO_VIDEO_SS_BURST + 1) * (FX3_EP_ISO_VIDEO_SS_MULT + 1) * 1024) = (0x07+1)(0x01+1)*1024=16k

0x01, /* Servicing interval for data transfers */

It means cypress will report max palyload size is 16k, bandwidth is 16kB/125us *8= 1Gbps. and i capture usb package:

It is correct. Could  i reduce the bandwith further?

How i reduce the wBytesPerInterval and open camera successfully?

Thanks!

Hi,

I am interfacing an Omnivision image sensor (OV9734) with the CX3 bridge .

The image sensor and current cx3 receiver configuration are like below:

But I have two questions:

1.  Why do the following problems occur:

2.I have read the KBA: Streaming RAW10 Format Input Data to 16/24-bit Output Format in CX3 MIPI CSI-2 - KBA224387,

then I realized that I should replace CY_U3P_CSI_DF_RAW10 with CY_U3P_CSI_DF_YUV422_8_2, but I have no ideal how to change  the UVC Descriptor and probe control structures of my firmware and how to calculate the parameter of re-writing . So can I use the code in the example OV5640?
