Hi,

It seems you are using the built-in ICDI debug probe that is part of this Launchpad, is that so? If so, unfortunately this legacy design does not have many diagnostics that could give a better idea on what may be going wrong.

At any rate, you can always try to find the error message on discussions around the internet. A few highlights are shown below:

In the future, if you find this issue after loading code to your board, check the reference below with a thorough discussion:

Hope this helps,
