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 ?

Only if you bring your own air )) This chip has no wireless capabilities.

Actually I am aware of that, but i need Flash memory partition details for 256kb chip(STM32F446RTC6)

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

actually when we look into that table we can see the organization of flash, but which is for 512kb flash memory. which is difficult to map with 256kb flash.

Okey thank you for this info.

I will try now to load a bootloader and application into flash.
