i am using the STM32F769. The initialized variables are linked to ram0 (alias DATA_RAM) and not initialized variables are linked to ram3 (alias BSS_RAM) which are different as the mapping is as follows:
Code: Select all
ram0 : org = 0x20020000, len = 384k /* SRAM1 + SRAM2 */
ram1 : org = 0x20020000, len = 368k /* SRAM1 */
ram2 : org = 0x2007C000, len = 16k /* SRAM2 */
ram3 : org = 0x20000000, len = 128k /* DTCM-RAM */
What is the technical reason for this?
Thank you.
