7.3.2 Flash Memory Map

On the F28377D-SEP device, each CPU has its own flash bank [512KB (256KW)], the total flash for each device is 1MB (512KW). Only one bank can be programmed or erased at a time and the code to program the flash should be executed out of RAM. The following table shows the addresses of flash sectors on CPU1 and CPU2 for F28377D-SEP.
