LPCXpresso54628: Failed on chip setup: Ep(04). Cannot halt processor.

[donaldswearinge]

I've been working with LPCXpresso54628, Embedded Wizard, and MCXpresso for several months with no issues, downloading code via the LPC-LINK2 USB connection.

Now, out of the blue, I'm unable to download, getting the error listed in the heading.The screen of the LPCXpresso54628 is white and totally blank. Is the unit bricked, or do you have a suggestion as to how to get it back up and running?

Here's the entire console output of the process in MCUXpresso:

Hi  Donald Swearingen,

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
I'd like to suggest you to use the Flash Magic to do the total erase all flash operation for the LPC54628, then give debug a try again.
In further, please learn how to use the Flash Magic.

Have a great day,
TIC
