MCF8315A: Cannot control device through web app or desktop app - communication issues

Part Number: MCF8315A
Other Parts Discussed in Thread: MCF8315EVM

Hi there. Hoping to get some help getting the MCF8315A EVM board to work.

Since I see the same issues, on multiple computers, with either the web app or the desktop app, it can be assumed that I have tried all the steps on both.

I cannot communicate reliably with the MCF8315A board. I can't really even confirm that communication is happening at all. 

First things first. With the main page open on the web app, if I connect the board to USB, I get a green LED on the board and  I DO in fact get a green status light on the app and a message on the status bar that says first says something like "initializing connection" which then changes to "hardware connected". Great!

The next thing I do is go through the setup procedure under the gear icon.

I confirm that all the jumpers and switches are in the correct positions as per the "board configuration" step.

I then go to the "Connecting to the GUI" step. Step 3 says "Verify hardware connection" by clicking on "Read all registers" button and a few seconds later a pop up should come up indicating a successful read. I click the button and I get no pop up. Nothing happens at all. Ok, click it a few more times, click it faster, finally get a message that says "Read 0 registers". Hmm.

Well lets try and move on to the recommended default values page. Click on "Restore Default Values" and I get an error. 

" Load Registers: Could not parse file:TypeError: Cannot read properties of undefined (reading 'id')"

This looks like an error in communication, IE: the app is trying to get the ID of the board and is not getting a response.

I have tried a few other read/write operations but everything fails. I have done some research and looked for youtube videos but there isn't much out there for this particular board.

Here are the logs being produced.

Like I said this is happening on multiple machines with either the web app or the desktop app. Any ideas? Is this board defective? 

Thanks in advance.
