Hello.

Please tell me where to download CyUSB3 suite source code.

It seems that the file was once available at the page below, but I can't find the download link for the file. 

https://www.infineon.com/cms/en/design-support/tools/sdk/usb-controllers-sdk/ez-usb-fx3-software-dev...

* I have the zip file I downloaded long long ago but I'm not sure it's updated or not.

Thank you for your reply.

I confirmed that the creation date of the file (Apr 2016) you attached is same to the file I downloaded long ago.
However, I'm afraid that the source code is not updated.

The latest version of the USB suite is 1.2.3.20 according to the "UsbSuiteReleaseNotes.pdf" (002-23611, Apr 2018)
Also the creation date of the CyUSB.dll file which is bundled with FX3 SDK  1.3.4 is May 2018.
(The dll file states that its Product Version is 1.2.3.08, Assembly Version is 1.2.3.0, copyright year is 2018)

 

Is it possible to confirm that the source code is updated or not?

*This is just for information for developers who are working with FatalExecutionEngineError related to CyUSB3 suite.

In the case I was working with,

1) FatalExecutionEngineError is often ocurred while CyUSB3 is receiving data from FX3,
and, while other part of the application software works hard. 
(It is suspected that this problem has relation with garbage collection)

2) This problem is reproducible with  CyUSB.dll which is bundled with FX3 SDK 1.3.4.

3) This problem isn't reproduced with CyUSB.dll which is recompiled from the project of
the file  CyUSB3_USB_Suite_Source.zip  (Apr 2016) Jayakrishna attached.
The project file states that its version is 1.2.2.0.

 

The source code Jayakrishna provided made the software very stable and my problem is somehow completely solved.

Hmm, what was the primary cause of the problem...?

Hello,

I tested the new dll you provided and compared with the one which is bundled with the latest SDK.

1) the new dll Jayakrishna provided (Apr. 25 2022)
 -> no error out of 20 tries

2) the dll with latest SDK ( FX3 SDK  1.3.4,  May 08 2018)
 -> 10 errors out of 20 tries

The new one is obviously stable compared to the one with SDK.

I appreciate that if it's available to download the source code of the new dll.
