Trying to get an iMXRT685-EVK up running and going through the 'Getting Started with MCUXpresso SDK for RT600' document. I'm not able to run the HelloWorld project and getting the error message shown below.

I found some advice (NXP site) on erasing the FLASH but didn't succeed in doing so:

 

Screen capture attached!

 

I'm also working with the iMXRT1060 which hasn't caused similar issues.

 

Any ideas?
