EVMK2H Emulator (XDS200 mezzanine)

Hello TI Community,

I'm seeking some help or verification from someone that is knowledgeable about the EVMK2H kits.

I have recently been working with the Rev. 3 EVMK2H but I am having trouble with the included XDS200 Emulator Mezzanine card. I can not get the host PC does to detect a hotplug of the mini-USB connector on the mezzanine. No other emulators are connected to the EVM, just the mezzanine card. The host device manager shows no new devices, either.

On the other hand, the serial USB interface connector (on the main board) is detected normally. A Tiva C card with a built in emulator is also detected normally.

So, is there something unique here?  What am I missing?

With the disorganized nature of the documentation for the EVM, I can't find any specifics beyond a simple description for the emulator.

Also, when receiving the board, the programming and operational mode did not seem to conforms to the quick start guide. I had to muck around with the u-boot settings and such. Not that this has anything to do with my issue, but it seems to indicate a slap-dash QA process from Advantech.

I'm hoping there is not some HW issue and I'm simply having issues due to my ignorance.

Are there  some jumpers somewhere that need to be set? Some other settings on the PCB?

Thank you!

Best,

Jay.

    Apparently, there is what appears to be, a small "reset button" on the underside of the XDS200 module. Look closely along the outside edge. If I assert that pushbutton after the  system is powered up and running, it causes a hotplug event on the host.

    Subsequently, the device driver installs and it seems that all is normal. 

    While the situation is improved, I'd imagine this may need an update at somepoint to the power managment or other programmable logic... Unless it's just my board.

    Thanks.
