Hi, everyone

I am using the first core of the S32K358 chip to program, I want to put the BOOTLOADER program in the memory of PFLASH0, and then put the APP program in the memory of PFLASH1, can the APP run properly?

It doesn't matter which master accesses a flash block.

There's simple rule - if a block is being erased or programmed, it's now allowed to access this block. Only other blocks can be accessed at that time.

Regards,

Lukas

Hi @DouDou1 

Yes, there's no problem with this setup. There are four code flash blocks and read-while-write is supported between these blocks.

Regards,

Lukas

Hi,@lukaszadrapa,
Thank you for your reply, I want to know if the first core of the S32K358 chip can read-while-write all four code?
