I'm now having a problem when using printf in the main function.
I do observe the messsage from the console.
And the INTVEC is updated,but  the  interrupts can no longer be entered.



Without using the printf,  the interrupts work well.

I configured my project as the follows.


Is there any connection between the printf and the interrupts?

How can I use the printf  correctly without affecting the interrupts?


Best regards!
