Could you check HSE GPR register at 0x4039_C028? If HSE firmware is installed, the LC config word is ignored and the life cycle needs to be advanced via HSE service.&nbsp;</P> <P>Regards,</P> <P>Lukas</P> Mon, 08 Sep 2025 07:21:17 GMT https://community.nxp.com/t5/S32K/NXPS32K312-Restrict-the-debug-without-HSE/m-p/2164960#M52491 lukaszadrapa 2025-09-08T07:21:17Z
