Hi @LEEYM,
I'm not sure if I understood your question correctly. Are you looking for the variables view inside the debug session?
After establishing a debug session, you can use the "Variables" view to see the variables in the code:

If you are looking for the printf implementation (using semihosting), you can look at this community post: Example S32K312 Printf Semihosting DS3.5 RTD300 - NXP Community.
Best regards,
