Note: When booting from bank 2, in the application initialization code, you have to relocate the
vector table to bank 2 base address. (0x0808 0000) using the NVIC exception table and
offset register.
Physical remap
Once the boot pins are selected, the application software can modify the memory
accessible in the code area (in this way the code can be executed through the ICode bus in
place of the System bus). This modification is performed by programming the SYSCFG
memory remap register (SYSCFG_MEMRMP) in the SYSCFG controller.
The following memories can thus be remapped:
• Main Flash memory
• System memory
• Embedded SRAM1 (96 KB)
• FSMC bank 1 (NOR/PSRAM 1 and 2)
• Quad SPI memory
