I am using a LPC55S28 chip and wish to lock it down so only authenticated debug is possible. chapter 51 of the user guide explains quite a bit about the process but does not go into the specifics of how I actually set up a debug session in say MCUXpresso.
Is there a document explaining this anywhere?
Also its not entirely clear how I generate the credentials to make this work that would be useful information too. Examples showing how to generate keys similar to those in the secure boot section would help.
Thanks

Hello andrewfisher,
There is an application describe the steps, you can refer to:
https://www.nxp.com.cn/docs/en/application-note/AN13037.pdf
https://www.nxp.com/docs/en/application-note-software/AN13037SW.zip
Please pay attention, in AN, the SPSDK not the latest version, so the files in .zip folder not
suitable, can download newest example files in
https://github.com/NXPmicro/spsdk/tree/master/examples/dat
Another attention is do not use this step:
3.2.7 Revert device after programming CMPA
