S32K314 chip Debug port unlocking issue using Lauterbach

WZBGW — Thu, 14 May 2026 02:17:19 GMT

Hello NXP Technical Support:
I used Lauterbach to unlock the Debug port of the S32K314 chip according to the S32K3_SecureDeburg-UserGuide.pdf document, and the Debug port encryption method was password. The phenomenon is that unlocking failed, and the command window for unlocking success was displayed for a moment before disappearing. What's going on?
