Lauterbach_Script_For_MDM_AP_Mass_erase_S32K142

The script performs secure‑recovery and mass‑erase initialization of locked S32K142 MCUs by keeping the device in system reset (PTA5 RESET_B held low) from the moment of power‑on.


Before running the script, connect PTA5 (RESET_B) to VSS, power‑cycle the MCU, and start the script.


The script first reads the MDM‑AP Status register to determine the MCU’s security and flash‑ready state, then prompts the user to initiate a mass‑erase operation through the MDM‑AP Control register.


After the mass erase completes, the user is instructed to release RESET_B (remove PTA5 from VSS), after which the debugger re‑attaches and displays the flash configuration area at address 0x400.


Finally, the script prompts whether the MCU should be reprogrammed from an ELF file, and if confirmed, programs flash, loads the project, and executes it.
