Hi,

Can you please elaborate on the description of the problems?

I suppose you use S12DP512. This flash consists from 4 flash blocks.

There is one restriction, it is not possible to read from a flash block while it is being erased or programmed.

Therefore, the flash commands are execured from RAM.

Regards,

Daniel
