Boot modes
By default, the boot codes are executed simultaneously by both cores. However, by
programming the appropriate Flash user option byte, it is possible to boot from one core
while clock-gating the other core.
At startup, the boot memory space is selected by the BOOT pin and BOOT_ADDx option
bytes, allowing to program any boot memory address from 0x0000 0000 to 0x3FFF FFFF
which includes:
•
All Flash address space
•
Flash memory and SRAMs (except for ITCM /DTCM RAMs which cannot be accessed
by the Cortex®-M4 core)
