I am trying to stream 1080p60 video through a MultiChannel DMA buffer however we are running into a problem where after writing some amount of buffers to the FX3, we are seeing the current thread WATERMARK and READY flags stay asserted. This causes video data to backup on the FPGA side (because it cannot write due to buffers reporting as full) and then the system breaks. This issue is not present when streaming 480p60, 720p60 or 1080p30. I tried increasing the number of buffers in the  MultiChannel DMA from 4 to 8 to try and increase the number of available buffers but I saw no difference. If I switch to a single channel DMA, video can be sent out as expected however I am unsure if it is truly 1080p60 because the docs say I need to use a MultiChannel DMA to get the FX3 data bandwidth required to output 1080p60.

In the included photo, You can see multiple writes and then suddenly both WATERMARK and READY assert at the same time.

Is there any way to check if buffers are getting stuck or are full through the FX3 firmware? Could I attach a UART debug print to when this is occuring?

The BT601 format data of the f 5640 module has been successfully debugged according to the 《Infineon-AN75779 _How_to_Implement_an_Image_Sensor_Interface_with_EZ-USB_FX3 _in_a_USB_Video_Class_(UVC)_Framework-ApplicationNotes-v13_00-CN.pdf》document and the "cyfxuvc_an75779.zip" code. Is there any reference material for the f 5640 module BT656 format data to fx3 ?

Hi,

Following this thread Looking-for-FX3-descriptors-that-work-with-WinUSB/td-p/101661 , we are using the WinUSB driver to communicate with our FX3 chip (CYUSB3011). 

Now, we are at a point where we would want to be able to reprogram the chip without using the Control Center given in the SDK.

We saw that the code for the Control Center was also in the SDK so we took a look into it. It seems like the DownloadFw is used with a CCyFX3Device. However, we don't directly use the CyAPI since we use the libusb functions in our code.

So my questions are, is it possible to reprogram the device even tough we are using the WinUSB driver? And if so, is there any example or a document that could help us with it?

Thank you and have a nice day,

Keven

Hello, 

I have developed my firmware program and now I want it to be freely named in the device manager, how do I change it?
Thanks.

Sir / Madam,

Could you please help me in fixing:  "sudo ./install.sh" reports " ../include/controlcenter.h:9:10: fatal error: ui_controlcenter.h: No such file or directory " ?

Sincerely,

Liu

I just tried to download the latest FX3 SDK, which still seen to be version 1.3.4.
The last I could find about 1.3.5 was that it was scheduled to be released in July, buyt now it is end of october.

Solved: FX3 SDK 1.3.5 release - Infineon Developer Community

Any news on this? Or where can I find th updated version?

Hello,

I want to read datas from the FPGA, and  I did that with the" XferData" function. But I want to keep reading the data to ensure the state in the FPGA process,  I failed with using the "for " and "while " ,just like the "error.png". I found that I can read for some times, maybe as 50 - 60 times,  then the usb module was not working.....

Best regards,

Hello,

I am working on a project that uses the EZ-USB FX3 USB 3.0 device controller with RTOS from the SDK examples.
Not Important but my current problem is: there is a race condition between Uart access between the AppThread main loop (which is used to sync the UART communication in certain intervals) and the asynchron Usb Setup request Callback handler function. -> USB Message handling UART function is being executed while the main loop UART function is being executed.

What I need to know to fix this is: How is the UsbSetupCB handled.
-> is my RTOS AppThread interrupted (and stopped?) while the Usb Setup request is being handled
or is another thread spawned in the RTOS to handle the UsbRequest in parallel?

general info to convey the setup:
(This is not my code but conveys the structure, USB & UART is set up properly)

AppThread_Entry(){
    ApplnInit(void)
    for (;;) {
        CyU3PThreadSleep(1000);
        len = CyU3PUartReceiveBytes(&inBuf, 1, NULL);
    }
}
ApplnInit(void){
    CyU3PUsbRegisterSetupCallback(AppUsbSetupCB)
}
AppUsbSetupCB(){
    case CY_U3P_USB_VENDOR_RQT:
    isHandled = VendorRequest(bReqType, bRequest, wValue, wIndex, wLength);
    return isHandled;
}
VendorRequest(){
    CyU3PUartTransmitBytes(&outBuf, 1, NULL);
    CyU3PUartReceiveBytes(&inBuf, 1, NULL);
}
