/* The STM32F746NGH6 has 1024Kb 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 STM32F746NGH6, 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 STM32F746G
|
||||||
|
* DISCO board, the BOOT0 pin is at ground so by default, the STM32 will boot
|
||||||
|
* to address 0x0020:0000 in ITCM FLASH.
|
||||||
|
*
|
||||||
|
* The STM32F746NGH6 also has 320Kb of data SRAM (in addition to ITCM SRAM).
|
||||||
|
* SRAM is split up into three blocks:
|
||||||
|
*
|
||||||
|
* 1) 64Kb of DTCM SRM beginning at address 0x2000:0000
|
||||||
|
* 2) 240Kb of SRAM1 beginning at address 0x2001:0000
|
||||||
|
* 3) 16Kb of SRAM2 beginning at address 0x2004: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.

* 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 STM32F746NGH6, 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 STM32F746G
|
||||||
|
* DISCO board, the BOOT0 pin is at ground so by default, the STM32 will boot
|
||||||
|
* to address 0x0020:0000 in ITCM FLASH.
|
||||||
|
*
|
||||||
|
* The STM32F746NGH6 also has 320Kb of data SRAM (in addition to ITCM SRAM).
|
||||||
|
* SRAM is split up into three blocks:
|
||||||
|
*
|
||||||
|
* 1) 64Kb of DTCM SRM beginning at address 0x2000:0000
|
||||||
|
* 2) 240Kb of SRAM1 beginning at address 0x2001:0000
|
||||||
|
* 3) 16Kb of SRAM2 beginning at address 0x2004: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.
|
||||||
|
*
|
||||||
|
* For MPU support, the kernel-mode NuttX section is assumed to be 128Kb of
|
||||||
|
* FLASH and 4Kb of SRAM. That is an excessive amount for the kernel which
|
||||||
|
* should fit into 64KB and, of course, can be optimized as needed (See
|
||||||
|
* also configs/stm32f746g-disco/scripts/kernel-space.ld). Allowing the
|
||||||
|
* additional does permit addition debug instrumentation to be added to the
|
||||||
|
* kernel space without overflowing the partition.
|
||||||
|
*
|
||||||
|
* Alignment of the user space FLASH partition is also a critical factor:
|
||||||
|
* The user space FLASH partition will be spanned with a single region of
|
||||||
|
* size 2**n bytes. The alignment of the user-space region must be the same.
|
||||||
|
* As a consequence, as the user-space increases in size, the alignment
|
||||||
|
* requirement also increases.
|
||||||
|
*
|
||||||
|
* This alignment requirement means that the largest user space FLASH region
|
||||||
|
* you can have will be 512KB at it would have to be positioned at
|
||||||
|
* 0x08800000. If you change this address, don't forget to change the
|
||||||
|
* CONFIG_NUTTX_USERSPACE configuration setting to match and to modify
|
||||||
|
* the check in kernel/userspace.c.
|
||||||
|
*
|
||||||
|
* For the same reasons, the maximum size of the SRAM mapping is limited to
|
||||||
|
* 4KB. Both of these alignment limitations could be reduced by using
|
||||||
|
* multiple regions to map the FLASH/SDRAM range or perhaps with some
|
||||||
|
* clever use of subregions.
|
||||||
|
*
|
||||||
|
* A detailed memory map for the 112KB SRAM region is as follows:
|
||||||
|
*
|
||||||
|
* 0x20001 0000: Kernel .data region. Typical size: 0.1KB
|
||||||
|
* ------- ---- Kernel .bss region. Typical size: 1.8KB
|
||||||
|
* 0x20001 0800: Kernel IDLE thread stack (approximate). Size is
|
||||||
|
* determined by CONFIG_IDLETHREAD_STACKSIZE and
|
||||||
|
* adjustments for alignment. Typical is 1KB.
|
||||||
|
* ------- ---- Padded to 4KB
|
||||||
|
* 0x20001 1000: User .data region. Size is variable.
|
||||||
|
* ------- ---- User .bss region Size is variable.
|
||||||
|
* 0x20001 2000: Beginning of kernel heap. Size determined by
|
||||||
|
* CONFIG_MM_KERNEL_HEAPSIZE.
|
||||||
|
* ------- ---- Beginning of user heap. Can vary with other settings.
|
||||||
|
* 0x20004 c000: End+1 of SRAM1

* The external functions, stm32_spi1/2/3select and stm32_spi1/2/3status must be

||||||
|
* include/nuttx/spi/spi.h). All other methods (including stm32_spibus_initialize())
|
||||||
|
* are provided by common STM32 logic. To use this common SPI logic on your
|
||||||
|
* board:
|
||||||
|
*
|
||||||
|
* 1. Provide logic in stm32_boardinitialize() to configure SPI chip select
|
||||||
|
* pins.
|
||||||
|
* 2. Provide stm32_spi1/2/3select() and stm32_spi1/2/3status() functions in your
|
||||||
|
* board-specific logic. These functions will perform chip selection and
|
||||||
|
* status operations using GPIOs in the way your board is configured.
|
||||||
|
* 3. Add a calls to stm32_spibus_initialize() in your low level application
|
||||||
|
* initialization logic
|
||||||
|
* 4. The handle returned by stm32_spibus_initialize() may then be used to bind the
|
||||||
|
* SPI driver to higher level logic (e.g., calling
|
||||||
|
* mmcsd_spislotinitialize(), for example, will bind the SPI driver to
|
||||||
|
* the SPI MMC/SD driver).
