Hello, I am working with the CX3 Denebola Dev Kit. I am trying to get the device to enumerate as a USB 3.0 device and it will not. It does not seem to want to connect to my host computer after CyU3PConnectState(CyTrue , CyTrue) is called. I am using FX3 SDK 1.3.4 and the default firmware from e-con systems for this board with the OV5640 imager, along with the default USB cable included with the board. USB 2.0 works just fine and I can stream with the imager when I disable Super Speed or just connect it to a USB 2.0 port.Show Less
I have FX3 and I use it for ISOC/Interrupt/BULK testing with the streamer app (add the app below)
I wonder if there is an API for the app,
Like Windows CMD command for
And so on…. Just like in the UI of the app
And if there is, does it have documentation?
I think it will be useful for developing tools.
Thanks for helping,
Hello all, I am working on FX3 while interfacing a camera sensor with it. I need to debug and as mentioned that there are some ways to do so using segger debugger. I want to connect it on board. What pins I need to use to connect the segger JTAG (2*10 pins connector).

We are using CYUSB3KIT-003 (the P/N of the chip is CYUSB3014) to design a camera. We need to send a leader and a trailer as single transfers before and after each frame. So I used the override mode to add the leader and trailer. I modified the AN75779 to test the override mode.
I add the leader in the GPIF CB function and the trailer in DMA CB function. I also added 2 states in the GPIF state machine: SOF0 and SOF1 to get the SOF signal from the camera (it’s a pulse 5ms before FRAME VALID signal ) to interrupt the CPU. In these 2 interrupts, I add the 52 bytes Leader of the frame. The resolution of my design is 1920*1200 Mono8 (1 byte per pixel) and the frame rate is 30 FPS. I set the buffer burst size to be 18K (18*1024). So there should be 125 transfer of 18K blocks, one leader and one trailer for each frame. I used AMCap to start the transfer though I know there will be no video in the viewer. I only need to see the USB traces.
But the trace I got is not as my expectation. The data blocks will sometimes be 124, and sometimes there will be one data block between the leader and trailer. The app will stop running after several seconds with an EP_UNDERRUN error. You can see the details in the attachment.
Please kindly give me some help.
Thank you much in advance.
I'm using CX3(CYUSB3065).
When test using Stremer Program, the USB hub Operates normally.
But Fail occurs when connecting directly to PC.
How can I fix the problem?
Hi, I'm Jay.
The question below has ended, so I'm posting the question again like this.
1. As the message is not working with the default SDK provided firmware also, could you tell me how the uart is connected to the PC?
- I use to connect USB 3.0 cable or USB2.0.
- As shown in the picture below, connect it directly to the PC.
- There is using 32bit set mode, but It occurred same problem from 16bit set mode.
2. Could you try using different cables and check if the issue is seen there also?
- There are same problems from USB 2.0 cable and usb 3.0 cable. It receive the same broken data to connect from various cables.
3. Could you also try using different PC and see if the issue persists.
- I used to another PC's, then It occurred same situations(received broken data).
4. Check the last point in the given KBA : https://community.infineon.com/t5/Knowledge-Base-Articles/FX3-CyU3PDebugPrint-Not-Printing-UART-Debu.... Also compare your schematics with AN70707 schematic checklist.
- This check list are usb setup configurations setup from 16bit or 32bit. and My test board operates normally.
- But Broken data continues to enter intermittently, causing problems.
- Please advise if this problem can occur in software or hardware regarding data breakage.
We've tried so many software attempts, and we can't find a clear answer to this intermittent data breaking problems.
Please help me as much as possible.
I wonder if Cypress can confirm that there is no software problem.
If you are confident that there is no SW problem, it will be a hardware problem and redesign the hardware.
Thank you.Show Less
I am trying develop an UVC application with the FX3 board(CYUSB3KIT). I am using as a base the AN75779 document and the UVC_AN75779 example project. I needed to modify the project, based on the FX3 Technical reference guide. I had to add some simple GPIO and one complex GPIO for a clock signal. The documentation says i had to bitmasking the gpios(like in the cyfxgpiocomplexapp and the cyfxgpioapp example projects), but if i masked them the board not even enumerate. I could successfully setup the simple gpio pins if i did not masking them, but initialize them with override in the "CyFxUVCApplnInit" thread. But for the complex gpio pin i was not able to use this method. Can you help what can be the problem?Show Less
