I AM  Trying to Install this ezusbfx3sdk_1.3.5_Windows_x32-x64.exe in my Pc. But it throws an Error showing MICROSOFT.NET version should be above 3.5 or 4 even though my  current version is 4.0 .please guide me for the installation of this sdk exe.Mention below is the error which it shows during Installation.

And mentioned below is my Microsoft.NET Framework verion .

so please guide us in the process of installation of the skd it would be very greatful.

Thanks & Regard's

I need a usb C power delivery (upto 100W) adapter/power bank design files using this chip CYPD7271-68 QXQ to understand the hardware of this chip. can somebody kindly provide that?

AN84868 is followed to implement using CX3 to configure FPGA. To be able use the FPGA configuration utility tool, descriptors are the same for AN84868 for FPGA configuration application firmware. After FPGA configuration, firmware switches to CX3 UVC application.  FPGA configuration  part is good, after switching to UVC application, video streaming is also good. Yet, UART is not able to send out debug information anymore in UVC application.  UART debug works during FPGA configuration and printout information on data count for FPGA configuration process.

IO matrix configuration is the same for FPGA configuration application and for UVC application, i.e.  I2C, SPI and UART peripherals  are all enabled. 

I am using GPIO 48 to 49 as the UART tx and rx. 

What could be the problem?

Thank you for help in advance. 

Hey all, i've been trying to get a YUV2 demo to work on the FX3's memory, so far i've successfully modified the MJPEG demo to output a 96x96 yuv2 image, and on windows the camera preview does work (i see my 4 frame sample), but starting a stream does not work properly and crashes the app.
When running this on linux, it does not work at all, v4L2 reports:

VIDIOC_STREAMON returned -1 (Input/output error)

 Looking at wireshark, the ONLY difference i can spot between MJPEG and YUV2 (besides the config change in the format and frame descriptors obviously) are a wrong bAlternate setting requested by the host to the FX3 when the YUV2 fw is loaded, which causes the isochronous stream to never start:

This should be 1 instead, like in this mjpeg capture of the same command which does start streaming:

This causes an issue with this peice of code and never starts the stream:

            /* Start the video stream if the streaming interface has been selected. */
            if ((interface == CY_FX_UVC_INTERFACE_VS) && (altSetting != 0))
            {
                CyU3PDebugPrint (4, "STARTS\r\n", evtype);
                CyFxUVCApplnStart ();
            }
            break;

I've attached the wireshark log for both the usb descriptors, to show that their endpoint configs are the exact same (attached as C files because the forum doesn't take .txt), besides cyfxuvcdscr.c and the frames themselves nothing has been modified from the sample. I'm on the latest version of the SDK and the working mjpeg demo has been compiled on the same sdk as the non working one.

Any clue as to why this might be occuring?

As mentioned in the title, I use Control Center on PC to recongnize CYUSB3014-BZXI device on PCBA and that's OK. 
Here Control Center  is in Cypress's suite for FX3 device.

However, when I power off my PCBA and PC, or just power off PCBA, Control Center occasionally shows no device after power on. On this circumstance, I could only unplug USB3.0 wire and plug it again, and it's OK again.

Add: PC's OS is win10.

It's not OK as follow:

Next it's OK after re-plug.

Hi ,
 We are working on FX3 cypress CYUSB3014  and using TI (Texas Instrument ) image file to  configure the FX3 . Using Streamer application  we checked the throughput , achieved 256300 KBps . We need to achieve maximum speed around 4Gps . Please help us to achieve this speed and please  suggest correct image file also to achieve the same .

Now we can modify the source pdo use dpm_update_src_cap() , CCG5 send source capability to device, and we want to know if  there is any function can get the rdo from device

Hardware using FX3 kit, FPGA generate image to FX3 display in the host computer, using an75779 project, resolution 1920 * 1080, frame rate 30, 8-bit data line, with amcap image is normal, changed to 32-bit data line, black screen no image. The state machine has been changed to 32 bit, the programmed limit value has been changed to 4091, and isDQ32Bit is set to CyTrune, please correct me as to where the problem is. Attached is the project file.

After trying to debug some of the available C++ examples like BulkLpAutoCpp, i've found out that any C++ based project will not properly debug under openocd and will halt instead. C projects debug just fine and i've already established that my debugger config is exactly the same as in the docs.

So i would like to ask how could i debug my C++ projects using openOCD on boards like the FX3 SuperSpeed explorer? Going back to pure C projects isn't really an option and debugging only through uart is insufficient (especially to check register values after an issue).

Hi,

I am using the following eval board and not using RTOS in my project. I am trying to setup an interrupt based systick timer and looking for some information on how to do so since I haven't setup any interrupts yet.
