Red Exclamation With Files In rt_core folder

[running_gao]

Thanks for working on the problem for me. I am using Win10, LPC51U68 MCU and Link2. I upgrade 2 files (.project and .cproject) today and the icon shows a red ‘!’. I suspect it means ‘not push’ up to app. If so, could you please advise how to fix it? Thank you!

I use win10 but don't have your problem. how to show the green tick and red exclamatory mark? How to reproduce your issue?

Can your project work normally with MCUXpresso IDE now?

Have a nice day
