S32K3 FLASH write

[DouDou1]

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?

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.

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?

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.
