Hi,

I am using Cypress FX3 CYUSB3KIT-003 DVK Kit, and cyfxbulksrcsink example firmware is used from the cypress installation directory.

I am not able to run Test_SE0_NAK On cypress FX3 Device, It is not responding with NAK when the test is executed.

Test_J, Test_K, and Test_Packet are working fine.

Can you suggest any thing

Thanks & Best Regards

Hello Prasannakumar,

- Please confirm that the device enumerates in the test PC.

- what is the cable length used. You can also try testing with a shorted cable length. (refer the attachment)

Also probe the USB lines (between DUT and  SQUIDD board) and share the traces.

Hello Prasanna,

Please let me know which SDK version are you suing for the test.

If it is SDK 1.3.3, you need to upgrade it to SDK 1.3.4

We have seen some issue with SDK 1.3.3 when you use latest EHCI HS Electrical Test Tool. It is fixed in SDK 1.3.4.

Hi Rashi,

I am using SDK 1.3.3, I will update to 1.3.4 and use same cyfxbulksrcsink FW. So I will be able to run Test_SE0_NAK test case right ?

Any other changes need to be done to the application FW?

Thanks & Regards

Hi Rashi,

I updated to SDK 1.3.4 and tested Test_SE0_NAK  But still I am not getting NAK.

In which version of EHCI HS Electrical Test Tool it will work. If you mention. I will verify with that version of EHCI HS Electrical Test Tool.

Thanks & Regards

Hello Prasannakumar,

You can test with the version which is available on usb.org USBHSET version 1.3.5.4 for EHCI 64-bit | USB-IF

If still it fails. Please share the usb traces.

Hi Rashi,

With above mentioned version I can use SDK 1.3.3 generated Firmware or do I need to use SDK 1.3.4 generated version.

If I need to use SDK 1.3.3 generated firmware means which version of EHCI HS Electrical Test Tool need to be used.

At present we used EHCI HS Electrical Test Tool Version 1.3.5.0.

Same version being used on Both SDK-1.3.3 and SDK-1.3.4 generated firmware.

Thanks & Regards

Hello,

You can test SDK 1.3 4 with EHCI HS Electrical Test Tool Version 1.3.5.0.

If you get EHCI HS Electrical Test Tool Version 1.3.1.3 , you can test SDK 1.3.4 with that also.

Hi Rashi,

We are using the same setup as you mentioned in your image.

It is working with 4"cable and as well with 1 mts cable. Earlier I was testing with 5 mtr cable with Cypress FX3 DVK Kit.

As of now with SDK 1.3.4 It is working with Cypress FX3 DVK (CYUSB3KIT-003) Kit with 4" and 1 mtr cables.

I will test the same with my custom board and I will let you know the status.

Thanks for your support.

Best Regards

Prasanna
