/* The STM32F765IIT6 has 2048 KiB of main FLASH memory. This FLASH memory
|
|
* can be accessed from either the AXIM interface at address 0x0800:0000 or
|
|
* from the ITCM interface at address 0x0020:0000.
|
|
*
|
|
* Additional information, including the option bytes, is available at at
|
|
* FLASH at address 0x1ff0:0000 (AXIM) or 0x0010:0000 (ITCM).
|
|
*
|
|
* In the STM32F765IIT6, two different boot spaces can be selected through
|
|
* the BOOT pin and the boot base address programmed in the BOOT_ADD0 and
|
|
* BOOT_ADD1 option bytes:
|
|
*
|
|
* 1) BOOT=0: Boot address defined by user option byte BOOT_ADD0[15:0].
|
|
* ST programmed value: Flash on ITCM at 0x0020:0000
|
|
* 2) BOOT=1: Boot address defined by user option byte BOOT_ADD1[15:0].
|
|
* ST programmed value: System bootloader at 0x0010:0000
|
|
*
|
|
* NuttX does not modify these option byes. On the unmodified NUCLEO-144
|
|
* board, the BOOT0 pin is at ground so by default, the STM32F765IIT6 will
|
|
* boot from address 0x0020:0000 in ITCM FLASH.
|
|
*
|
|
* The STM32F765IIT6 also has 512 KiB of data SRAM (in addition to ITCM SRAM).
|
|
* SRAM is split up into three blocks:
|
|
*
|
|
* 1) 128 KiB of DTCM SRM beginning at address 0x2000:0000
|
|
* 2) 368 KiB of SRAM1 beginning at address 0x2002:0000
|
|
* 3) 16 KiB of SRAM2 beginning at address 0x2007:c000
|
|
*
|
|
* When booting from FLASH, FLASH memory is aliased to address 0x0000:0000
|
|
* where the code expects to begin execution by jumping to the entry point in
|
|
* the 0x0800:0000 address range.
|
|
*
|
|
* Bootloader reserves the first 32K bank (2 Mbytes Flash memory single bank)
|
|
* organization (256 bits read width)
