LPC54608 USB High Speed PHY Test Modes

guitardenver — Mon, 20 Sep 2021 20:26:46 GMT

Hello,

I was wondering if the standard USB "HSETT" PC software can work with the LPC54608 MCUs?

I have never done USB-IF testing and want to make sure our lab can do what they need to do. I have installed the xHCI HSETT tools and can see the device, but when I tell it to enter J or K testing, it says "Operation Failed".

1) Is the MCU high speed device controller compliant for these tools?

2) If they are not, does that mean I need to write firmware for the testing lab that will put the device in a testing mode via the

DEVCMDSTAT register?

3) Am I just using the wrong tool?

I never used "HSETT" , I suggest you checking the tool vendor if it can support standard HS USB.

If you use NXP SDK demo code, you will see USB PC testing tool Sniffer under USB demo folder. I suggest you using it.

I know some users use bus hound. But I don't have full test on it.

Have a nice day,

Jun,

Thanks for the Reply. I will check our bus hound and the demo.

Which sdk has that demo code. I don't see it in the lpcxpresso54608 version 2.7.

The HSETT is the official tool from USB.org. You can find all their tools here
