S32K142 chip is secure and unable to mass erase

Hello @danielmartynek, & @lukaszadrapa

I am using S32K142 controller for our hardware. We have secured it with FSEC register with MEEN bit enabled. however, unable to perform mass erase with S32k.cmm mentioned in Solved: In s32k118 Cant write FSEC bit Setting using T32 - NXP Community script using lauterbach. when tried system.up command "bus error generated by CPU" is thrown.

When MDM-AP register is read using lauterbach debugger. The value is 0x7F. Can you help me how to perform mass erase?
FYI, debug interface is SWD

Thanks in advance

Hello @firmsol,

I have posted a new script here:

Could you run or step through it on your side?
