I have STM32F303 Nucleo board (Datasheet), and I work with Mbed IDE, which allows me to compile code to the board. The compiled code is in .bin format.

Some relevant information from the datasheet:

  • Cpu is Arm-v7
  • Flash memory starts at 0x8000000
  • SRam starts at 0x20000000

I want to load in IDA the .bin file, and map the ROM and RAM sections according to the memory map.

I tried many different configurations in the memory organization form, but couldn't find the one that represents the actual memory. The default form as IDA recognizes it:

enter image description here

From what I understand, the size of the bin file is 0x632c, which includes both the RAM and ROM. Any ideas of how can I make the cut between the two sections? And when I do, what is the right way to fill it in the memory form?

The image is for the flash so it contains only ROM. RAM is initialized by the startup code by copying some bytes from the ROM. This should work:

  • ROM start and load base: 0x8000000
  • RAM start: 0x20000000
