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 .

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).

I try to debug the example firmware of the Super Speed Explorer Kit USBBulkSourceSinkLED on our custom PCB with a FX3S on it via JTAG. I changed the LED_GPIO define to (49) because our LED is at this pin. I Am using EZ-USB FX3 SDk V1.3.4. on a Windows 10 PC.

For debugging we tried to use the SEGGER Jlink  PLUS Compact with the ARM 14-pin Adapter and  J-Link Software and Documentation Pack v7.96b. We followed the Section 3.1 in the EZUsbSuite User Guide, but without success.

Error Message from EZ USB Suite with JLINK:

 Error in final launch sequence

Failed to execute MI command:

tbreak main

Error message from debugger back end:

Cannot access memory at address 0x40004a00

Cannot access memory at address 0x40004a00

So we build a PCB with a 14-pin JTAG Header and the schematic from the Explorer Kit with the CY7C65215-32LTXI on it to get an integrated Debugger. We configured it like the Explorer Kit using the Cypress USB-Serial Configuration Utility User Guide. We followed the Section 3.7.2 JTAG from the SuperSpeed Explorer Kit User Guide as well as 3.2. Debugging with OpenOCD Section from EZ USB Suite User Guide.

Error Message from EZ USB Suite with CY7C65215:

Error in final launch sequence

Failed to execute MI command:

continue

Error message from debugger back end:

Warning:\nCannot insert breakpoint 1.\nError accessing memory address 0x400040b0: (undocumented errno -1).\nCannot insert breakpoint 3.\nError accessing memory address 0x400040dc: (undocumented errno -1).\nCannot insert breakpoint 2.\nError accessing memory address 0x40004a00: (undocumented errno -1).\n

What does these error messages mean ?

Are there known issues with custom hardware and debugging via JTAG with the FX3S ?

We are working on a project that streams 1936x1552 RAW12 data from IMX623 imager from Sony. I was able to get an image, but only if I set the output pixel clock for the CX3 MIPI config over 100 MHz and the image does not display correctly(on Windows camera app, VLC) and after some time the stream stops and I get a CB Failure. 

I made another thread and the solution was to allocate more memory to the DMA buffers, but I wasn't able to.
I modified CY_U3P_SYS_MEM_TOP to 0x40080000 and CY_U3P_MEM_HEAP_BASE in cyfxtx.c and the fx3.ld file like here, but I still have the CB failure, do I need to change anything else? I tried increasing CX3_UVC_DATA_BUF_SIZE in cycx3_uvc.h, but I don't get an image at all after that.

I refer to someone else's project on the Internet, but after loading it in, I found that I can't find any of its header files, how should I add the path to the header files?
