Hi,
I looked at this topic -https://community.cypress.com/t5/USB-Superspeed-Peripherals/FX3-multiple-descriptors/m-p/81912
and I’m trying to do it also but I’m having trouble with opening the socket,
Is there any chance that you have example of multi endpoint? Or can guide me how to open socket for each of the endpoint?
I want to create FX3 with
- ISOC in and out endpoint
- Interrupt in and out endpoint
- Bulk in and out endpoint
Thanks,
EliW.

Hi EliW,
No, it is not FX3 limitation.
Please find the attached firmware project folder. ISOC IN endpoints gives speed above 100KBps when there are no bulk transfers happening simultaneously.

Hi EliW,
Could you share your firmware project folder as well as the UART Debug prints with us to try to reproduce the issue at our end?

Hi EliW,
From your firmware source code, I noticed that there are 4 endpoints,
2 Isoc IN and 2 Isoc OUT.
Considering these, there has to 4 channels, 2 MANUAL IN and 2 MANUAL OUT. But in your case you are using only 1 MANUAL IN and 1 MANUAL out channels (channel handle is same for two channels).
Kindly make distinct four channels for the four endpoints and let us know if you face the issue.

Hi EliW,
We will surely be able to help you.
May I know how is the data being expected to move among these 4 endpoints?
What is the exact application? What is the need for 2 Isoc IN and 2 Isoc OUT endpoints?

AliAsgar

Hi,
Im using C++ Streamer App for testing.
What I really need, is the ability to test
- ISOC in and out endpoint
- Interrupt in and out endpoint
- Bulk in and out endpoint
From one FX3 Device, so I need firmware with all the end point configured on it,
With the ability to change Burst size, Pkt Size, Pkt per Burst size (with respect to usb spec/device/host capability).
Do the FX3 have the capability to send and receive data in parallel?
For instance:
Connecting ONE FX3 with ISOC,Interrupt,Bulk endpoint to the PC ,
Opening C++ Streamer 3 times on the same pc with the FX3,
And trying to traffic to all endpoint simultaneously.
I'm using it to test my host&Hub with Multi Endpoint Traffic.
Can you help me with that kind of version?
(I included the C++ streamer that I'm using)
Thanks for your help,
EliW.

Hi,
First of all thanks for the support!!!
I got the firmware that you sent on the FX3, I can see the 6 endpoint(2 from each Type),
I tested theme and they all work, I have a problem only with the ISOC in endpoint, from some reason it only get to 100 KB/s
I'm using this DriverVer=11/08/2017,1.2.3.20,
Can you test the ISOC in endpoint on your side to if its reproduce at your end?
Again, thanks for the support!

Hi EliW,
Yes, even for us the ISOC in endpoint gets to 100KB/s.
The firmware is designed to check the feasibility of simultaneous data transfers on different endpoints of FX3, without much regard to the performance.

Hi,
Does it FX3 limitation problem? Because I'm testing it in In different situations and one of them is ISOC in only,
I'll be glad if I could reach faster speed then 100KB/s while operating only in ISOC endpoint in.(while the ether endpoint is there)
Thanks,
EliW.
