Hi@Helloyt

I tested your code several times on my S32M244EVB and did not encounter your problem, which bothered me.
You can look at the FSTAT register.

the problem also disappeard after I used another board to test the code

when I tried to read the FSTAT in the error board，I found the MCU was locked by mistake because the CSEC was enabled and i erased the sector0 without write 0x40d

So it hard to reaappear
