Hello,
I hope you are doing well.
To debug your MPU it is necessary to use an external debugger probe. You can consult tested hardware on NXP's web page on section: Hardware -> Partners -> Test Accessories and Debugger.
I suggest you any debugger from MACRAIGOR Systems, Wind River or any of ARM. The guide to use it will be on selected external debugger web page.
Best regards.
Jorge.
