Linker: Memory regions
This cheatsheet page contains an overview of available memory regions for use in the project level linker scripts. regions having a size are already defined in the linker scripts provided by STM32-base.
STM32F0
The FLASH_BANK_1 and SRAM_1 memory regions are available to all devices in the STM32F0 series. These devices to not support any other type of memory.
STM32F1
The FLASH_BANK_1 and SRAM_1 memory regions are available to all devices in the STM32F1 series. The FLASH_BANK_2 memory region is available for devices with more than 512KiB of flash memory. Some devices support external memory.
STM32F2
The FLASH_BANK_1, SRAM_1, SRAM_2, and BKP_SRAM memory regions are available to all devices in the STM32F2 series. All devices support external memory.
STM32F3
The FLASH_BANK_1 and SRAM_1 memory regions are available to all devices in the STM32F3 series. The CCM_SRAM memory region is available on some devices. Some devices support external memory.
STM32F4
The FLASH_BANK_1 and SRAM_1 memory regions are available to all devices in the STM32F4 series. The SRAM_2, SRAM_3, CCM_SRAM, and BKP_SRAM memory regions are available for some devices in varying configurations. Some devices support external memory.
The CCM SRAM available on STM32F4x3xx devices is available through the addresses defined for SRAM_2 and CCM_SRAM. Use only one of those to load data into this part of SRAM.
STM32F7
The FLASH_BANK_1, FLASH_ITCM, SRAM_1, SRAM_2, DTCM_RAM, ITCM_RAM, and BKP_SRAM memory regions are available to all devices in the STM32F7 series. All devices support external memory.
Note that the flash memory cannot be written to via the ICTM_FLASH memory region.
