FLASH erase fall

Hi, everyone

I am using the first core of the S32K358 chip programming, when I want to erase the C40_CODE_ARRAY_0_BLOCK_0 area of the program will report an error,but I can erase other areas such as C40_CODE_ARRAY_0_BLOCK_1, what is the reason?

Hi @DouDou1,

The flash block that is being programmed must not be read.

The code of the flash driver must be either in SRAM or in another flash block.

It has been discussed a few time here on the community.
