USB superspeed peripherals Forum Discussions

Hi, I'm Jay.

The question below has ended, so I'm posting the question again like this.

https://community.infineon.com/t5/USB-Superspeed-Peripherals/UART-output-message-pending-problem/m-p/324177#M28797

1. As the message is not working with the default SDK provided firmware also, could you tell me how the uart is connected to the PC?

- I use to connect USB 3.0 cable or USB2.0.
- As shown in the picture below, connect it directly to the PC.

- There is using 32bit set mode, but It occurred same problem from 16bit set mode.

2. Could you try using different cables and check if the issue is seen there also?

- There are same problems from USB 2.0 cable and usb 3.0 cable. It receive the same broken data to connect from various cables.

3. Could you also try using different PC and see if the issue persists.

- I used to another PC's, then It occurred same situations(received broken data).

4. Check the last point in the given KBA : https://community.infineon.com/t5/Knowledge-Base-Articles/FX3-CyU3PDebugPrint-Not-Printing-UART-Debu.... Also compare your schematics with AN70707 schematic checklist.

- This check list are usb setup configurations setup from 16bit or 32bit. and My test board operates normally.
- But Broken data continues to enter intermittently, causing problems.

- Please advise if this problem can occur in software or hardware regarding data breakage.

We've tried so many software attempts, and we can't find a clear answer to this intermittent data breaking problems.
Please help me as much as possible.

I wonder if Cypress can confirm that there is no software problem.
If you are confident that there is no SW problem, it will be a hardware problem and redesign the hardware.

Thank you.

I have some different USB devices, one of them sometimes have transfer problem on some particular laptop

When I try to display the USB event log, I found 

Normal device: 06 88 12 89 8a 8b 25 26 90 17

The one have transfer issue: 06 88 12 89 8a 8b 25 26 90 17 86 11 90 17 86 11 90 17

I  can  identify all the other code meanings with "CyU3PUsbLinkState_t" and  "USB event log values"

except 0x86, so, what does this code stand for? and maybe why it was generated also?

Thanks.

Hello,

          I'm using denebola kit for for development of DFU and I'm using this https://infineon.github.io/dfu/dfu_sdk_api_reference_manual/html/index.html , But I'm unable to find any name of Denebola kit while trying to creating project.

ruslan@Ruslans-iMac lib % make
g++ -dynamiclib libcyusb.c -o libcyusb.0.1.dylib -l usb-1.0
clang: warning: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated [-Wdeprecated]

Hello,

           I got confused with gpioSimpleEn and gpioComplexEn what are they and how to use it?

How to modify cypress USB firmware driver name? I cannot install the driver correctly after changing the contents of the cyusb3.inf file. This is because the hash value of the secure directory is inconsistent with cyusb3.inf. Can I change the contents of the secure directory? If not, how do you override to generate a secure directory and sign it?

 Hello,

I am using the FX3 Superspeed explorer kit and I want to use it with a camera module. I need to reset the image sensor and for that purpose i want use the GPIO 33. But i am not able to select pins over 27 with the GPIF designer. I am not able to remove the default reset pin from gpif designer because the state machine uses it. Can i somehow overcome this problem?

Hi,

I want to start a project that aims to connect MIPI CSI-2 cameras through USB. The most direct example in your webpage is this one: https://www.cypress.com/products/ez-usb-cx3-programmable-mipi-csi-2-usb-30-camera-controller

The problem is that the development kit that is required for this application (Denebola) has shown to be really hard to source. The last update in the webpage (https://www.cypress.com/documentation/development-kitsboards/denebola-usb-30-uvc-reference-design-kit-rdk) is from more than 3 years ago, which made us think that this is obsolete. We investigated if with the FX3 we could do the same, but it seems that FX3 can only connect cameras using a parallel interface (https://community.infineon.com/t5/USB-Superspeed-Peripherals/Which-CX3-FX3-development-kit-will-allow-me-to-hook-up-two/td-p/36750 ), which is not what we want. 

Is there a development kit for CX3 that is currently available? Are we missing something? Can the FX3 be used with CSI-2 cameras?

Thanks!
