USB Superspeed Peripherals

Hello,

sorry but I have to create a new discussion since my previous post (USB-IF Link Layer Test failed ) has been prematurely locked...

I tried to compile my firmware with SDK update 1.3.4 and, in fact, the fail TD.7.17 is gone... but TD.7.9, TD.7.11, TD.7.26 remains. All those fails are related to the new timings used and the Test Equipment (LeCroy M310P / Version: 3.60 Build 780) that USB org. now force to use with no alternative with Ellisys... What can I do now? The waiver ended Nov. 2018 and the device cannot be currently certified...

Moreover, with the update, reappeared a bug that was fixed by you a year ago (MyCase 00396780).

Please Cypress guys, can you contact me privately? I've some reserved data to share... and this matter begins to be quite urgent...

Thanks a lot for your support,

Dax

Here is the modified library which will pass timer tests without using Legacy Timers. Replace this library at the following location:

C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\fw_lib\1_3_4

Please put debug version in fx3_debug folder and release version in fx3_release version.

Hi DAVIDE,

To resolve the issue please go to settings and enable Support for legacy timers in USB compliance test utility. PFA screenshot for the same.

Kindly update me.

Thanks & Regards

Hi Abhinav, thanks for your reply.

Maybe I didn't explain myself... the device is currently under certification by an external lab. Is not possible to enable the support for legacy timers. This was possible till Nov. 2018, but now the device must work with the new timers to be certified.

For your information there is an open MyCase about this (00474977).

Best regards,

Dax
