There is a board named S32K144EVB-Q100 and the chip is FS32K144 HAMLL ON57U QAH2049H. In example flash_partirioning_s32k144 and running Debug_RAM with SDK 4.0.1, when function FLASH_DRV_EraseAllBlock is called, STATUS_ERRORis retured, and the flash status register (FSTAT) shown that ACCERE is error (1).board.jpg

Hi @lige960103,

Can you read the DEPART register?

Is the MCU already partitioned for CSEc? If so, you need to remove the partitioning by using the DBG_CHAL / DBG_AUTH commands.

This is what the ACCERR error means:
