Hi.,i use the j-link to debug the FX3,but it can not enter the CyU3PKernelEntry ();How can i debug enter the thread_enter function?

Hello,

I followed AN75779 to implement an 8 bit interface UVC. I have a card with a fx3 and a fpga. With fpga, I generate signals lv, fv and pixels (1920 * 2 * 1080 /  Y = counter;  U / V = 0x80). Everything works and I have a grey-scale image. But when I want to switch to 16-bit interface, it does not work. However, I modified the GPIF with a 16-bit bus and a limit of 8183 meter. Obviously, the state machine is stuck in a state PARTIAL/FULL_BUFF_IN_SC0/1. Any idea?

Thank you!

If any of you folks need a demo app using Qt that does USB transfers over a device, you can use the one attached to this post.

This project is compiled with MinGW and so CyAPI was also recompiled accordingly. The source project for that is in the CyAPI_lib_cpp folder and a simple makefile is included with that (you may need to modify that to make it work on your PC).

The Qt app itself is very simple -- it lists out all devices attached to cyusb3.sys and then enumerates the endpoints in a ComboBox. When you then click the "transfer data" button, it reads/writes 1 packet from/to the device.

Note that this is a very crude demo project. It's probably has bugs and is not good for production use as-is.

Does Infineon provide the Verilog or VHDL that would go on the Xilinx FPGA to support the CYUSB3035?
I searched through the FX3 webpage and related link starting @ https://www.infineon.com/cms/en/product/universal-serial-bus-usb-power-delivery-controller/peripheral-controllers/ez-usb-fx3-superspeed-usb-3.0-peripheral-controller/
I also looked through Application Note AN65974 "Designing with the EZ-USB FX3 Slave FIFO Interface" and the associated source files.
I’m looking for the RTL (Verilog or VHDL) for the Spartan FPGA that interfaces to the GPIF interface.

Hi,

I want the FX3 to Boot in bootloader mode so I'm using "Fx3BootAppGcc" project, I also want him to boot in SSC disable.

I'm trying to add the function "CyU3PUsbSSCDisable();" to the file "usb_boot.c"

Just before calling the function "CyFx3BootUsbConnect (CyTrue, CyTrue);"

When I try to build the project I get the next error:

11:04:14 **** Incremental Build of configuration Release for project Fx3BootAppGcc ****

cs-make: *** [Fx3BootAppGcc.elf] Error 1

11:04:15 Build Finished (took 737ms)

Can you help me add the function to this project and understand why the build doesn't work?

I attached the project that I'm trying to build.

Thanks,

• Hardware

  • host: tinker board 2s(rk3399)，kernel 5.13

  • slave: sg130gs(1280*720, YUYV, 30fps) + fpga(spartan 6) + cyusb3014, isochronous mode

• Problem

  • Run this script on host

    #!/bin/bash
    ​
    while : 
    do
            yavta -c30 /dev/video0
            sleep 2
            yavta -c30 /dev/video1
            sleep 2
    done

  • After random time(from minutes to hours), one of these cameras would be stuck

  • USB packets captured by tcpdump indicate that the host keeps polling(isochronous) the slave while the slave keeps responding with a data packet with zero-length

  • After this, if I restart the test script, the device that is stuck will be missed

• some trials on other settings also failed

  • ov5640(1280*720, YUYV,30fps) + cyusb3014, bulk mode

  • sg130gs(1280*720, YUYV, 30fps) + fpga(spartan 6) + cyusb3014, bulk mode

• In addition, test with a single camera is fine

Any ideas? thanks

Greetings,

I was wondering anybody encountered this failure: "Error, "Write failed. Aborting" while programming the firmware to the particular eMMC device, which is Koxia THGBMJG6C1LBAIL (8GB, eMMV 5.1 compliant). We use SanDisk iNAND7250 and this device has no issues to program the firmware using 'cyfwstorprog.exe.'

[Problem description]

Two partitions, and a user partition were successfully created but while programming the firmware, I got the following error:

Hi, I am working on interfacing ov7670 with CYUSB3KIT-003 as per this blog:

https://www.circuitvalley.com/2019/12/diy-cypress-fx3-usb3-usb-3-uvc-camera-ov7670.html?showComment=1638868010788#c6525421354026482197

Checked all the signals like PCLK,HREF,VSYNC,XCLK, all looks fine. firmware loaded to FX-3 but failed to display anything on vlc/webcamoid application. Here s the frame/buffer log...

Please help to resolve this issue. What more I should figure out.

Best Regards,
