Data Flash Memory: Value after Flashing again

Hello,

I am using S32k344 controller.

I have used 'C40_Ip_Example_S32K344' example for writing data in Flash memory. 

I have changed address to write data in 'Data Flash memory' block.

Once the code is run the data is successfully written in this section.

But even after re-debugging/re-flashing still the data is retained in this section.

I was expecting whole flash memory to be erased and programmed again after re-debugging/re-flashing.

Is this the expected behavior?

#dataflash #flash

#flashmemory

#s32ds

Hi @avinashstarkenn
