USB superspeed peripherals Forum Discussions

Hi ,
In fx3 controller ,

During streaming ,an unexpected interruption occurred due to a stop request. As I checked, the stop request has been came from the host, not from my application I have been used. I have attached the usb  log. kindly find the image (usb transaction image.png) .

In that image , during IN Transaction, before stop request occurs from host , I found that lup - 9182 , ldm -9385 , 810 itp value differs . During normal condition , lup - 15 or 14 or 13 , ldm - 15 or 14 or 13 , 1 or 2 itp. But before stop request came from host, lup,ldm,itp value differs. kindly check the image attached.

Then timing also differs during IN transaction. I have highlighted in image. After IN transaction which occurs in time 606.035 , the another IN transaction should occur.. but unfortunately it marked as error in  IN transaction(not ready error) in timing 606.051.   

Could you please explain why  After IN transaction timing (606.035) , this much of lup - 9182 , ldm -9385 , 810 itp is  occuring. Kindly check the timing in image i have  mentioned.

kindly verify  full transaction file i have attached (FX3_issue_infineon_trace.zip).

 Please comment your suggestion.

您好，请教个问题，我们在设置flagA为currentThreadDMAReady,设置flag B为currentThreadDMAWarterMark，在cyU3PGpifLoad()下方调用CyU3PGpifSocketConfigure(0,CY_U3P_PIB_SOCKET_0,6,CyFalse,1)，测试时，上位机不从USB取数，逻辑抓取信号发现flagA会被拉低，但是flagB一直是高，请问下可能是什么原因造成的呢？

Hi,

Im trying to enable power management tab in FX3 driver. as you can see in the image below there isnt power management tab:

Im trying to enable Low power states in FX3 using example lowpowertest

This is what I expect to be look like

你好：我现在能预览1600*1200分辨率的图像，但是用eCAM拍照功能，原有的分辨率都好使，我自己添加的分辨率1600*1200是黑屏，我用手机照射后拍照，发现有亮点，感觉是CyCx3_ImageSensor_Set_UXGA（）这个里面缺少一些操作步骤，以及SENSOR_UXGAConfigurationSettings（）缺少一些寄存器的设置，可能和AGC/AEC，有关，但是不知道怎么设置以及流程是怎么样的，希望帮助解决。

在例程cycx3_uvc_ov5640中有多种分辨率

1 默认的是640*480，请问这个默认值怎么改？

2 在电脑端用软件查看只有一个640*480的选项，请问怎么能进行选择？

Hello

I’m currently developing firmware to transmit image sensor (FPGA) from CX3 to U3V.

*Referenced the example : https://community.infineon.com/t5/Knowledge-Base-Articles/Implement-USB3-Vision-camera-with-EZ-USB-CX3-USB-3-2-Gen-1-device-controller/ta-p/445398

I was only testing in SuperSpeed, but when I tested in HighSpeed, I found that the Trailer comes before even all the data of one image is fetched. I thought this was happening because the speed at which the host fetches the image data and the speed at which the FPGA sends the image data do not match. So, I modified it to transmit one line from the FPGA and transmit dummy data, and then transmit the next line. However, no matter how long I give the dummy data, sometimes the partial buffer size is read differently when receiving the image.

Questions)

1. Can you tell me about the situations where the partial buffer size can be different?
2. Is the method to match the speed at which the host fetches the image data and the speed at which the FPGA sends the image data the control of Horizontal Blanking and Vertical Blanking?
3. Is it correct that the LV signal goes low during the time of receiving dummy data?
4. The sequence to receive one image is SWTrigger[0] -> Leader[0] -> image data[0] -> Trailer[0] from image 0. However, it is currently being delivered as SWTrigger[0] -> Leader[0] -> image data[0] -> Trailer[0] -> Leader[1]. Why is Leader[1] coming? Is it because of FV?

Image settings

• 1744x2400
• RAW14
• One image is transmitted per SWTrigger
