maybe difficult for you , most people will be satisfied with Table 4.

  • flash always starts at 0x0800 0000 .
  • flash end is sector7 for 512k , sector 5 for 256k.

whats so difficult here ?

Maybe you can ask a specific question beyond Table 4. Flash module organization in the reference manual.
