README
======
This README discusses issues unique to NuttX configurations for the
STMicro STM32F769I-DISCO development board featuring the STM32F769NIH6
MCU. The STM32F769NIH6 is a 216MHz Cortex-M7 operating with 2048K Flash
memory and 512Kb SRAM. The board features:
- On-board ST-LINK/V2 for programming and debugging,
- Mbed-enabled (mbed.org)
- 4-inch 800x472 color LCD-TFT with capacitive touch screen
- SAI audio codec
- Audio line in and line out jack
- Two ST MEMS microphones
- SPDIF RCA input connector
- Two pushbuttons (user and reset)
- 512-Mbit Quad-SPI Flash memory
- 128-Mbit SDRAM
- Connector for microSD card
- RF-EEPROM daughterboard connector
- USB OTG HS with Micro-AB connectors
- Ethernet connector compliant with IEEE-802.3-2002 and PoE
Refer to the http://www.st.com website for further information about this
board (search keyword: stm32f769i-disco)

STATUS
======
2017-07: The basic NSH configuration is functional using a serial
console on USART1, which is connected to the "virtual com port"
of the ST/LINK USB adapter.
2017-07: STM32 F7 Ethernet appears to be functional, but has had
only light testing.
Work in progress: Use LCD over DSI interface, rest of board.
Development Environment
=======================
The Development environments for the STM32F769I-DISCO board are identical
to the environments for other STM32F boards. For full details on the
environment options and setup, see the README.txt file in the
config/stm32f769i-disco directory.
LEDs and Buttons
================
LEDs
----
The STM32F769I-DISCO board has numerous LEDs but only one, LD3 located
near the reset button, that can be controlled by software.
LD3 is controlled by PI1 which is also the SPI2_SCK at the Arduino
interface. One end of LD3 is grounded so a high output on PI1 will
illuminate the LED.
This LED is not used by the board port unless CONFIG_ARCH_LEDS is defined.
In that case, the usage by the board port is defined in include/board.h
and src/stm32_leds.c. The LEDs are used to encode OS-related events as
follows:
SYMBOL Meaning LD3
------------------- ----------------------- ------
LED_STARTED NuttX has been started OFF
LED_HEAPALLOCATE Heap has been allocated OFF
LED_IRQSENABLED Interrupts enabled OFF
LED_STACKCREATED Idle stack created ON
LED_INIRQ In an interrupt N/C
LED_SIGNAL In a signal handler N/C
LED_ASSERTION An assertion failed N/C
LED_PANIC The system has crashed FLASH
Thus is LD3 is statically on, NuttX has successfully booted and is,
apparently, running normally. If LD3 is flashing at approximately
2Hz, then a fatal error has been detected and the system has halted.
Buttons
-------
Pushbutton B1, labelled "User", is connected to GPIO PI11. A high
value will be sensed when the button is depressed.
Serial Console
==============
Use the serial interface the ST/LINK provides to the USB host.
Configurations
==============
Common Configuration Information
--------------------------------
Each STM32F769I-DISCO configuration is maintained in a sub-directory and
can be selected as follow:
cd tools
./configure.sh stm32f769i-disco/<subdir>
cd -
Where <subdir> is one of the sub-directories listed below.
Configuration Directories
-------------------------
nsh:
---
Configures the NuttShell (NSH) located at apps/examples/nsh. The
Configuration enables the serial interfaces on UART1.
Otherwise nothing is enabled, so that config is a starting point
for initial testing.
Support for builtin applications is enabled, but in the base
configuration no builtin applications are selected.
nsh-ehternet:
---
Same as above but a lot more hardware peripherals enabled,
in particular ethernet, as well as networking stuff.

/* The STM32F769NIH6 has 2048Kb 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.
*
* In the STM32F769NIH6, 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 bytes. On the unmodified STM32F769I
* DISCO board, the BOOT0 pin is at ground so by default, the STM32 will boot
* to address 0x0020:0000 in ITCM FLASH.
*
* The STM32F769NIH6 also has 512Kb of data SRAM (in addition to ITCM SRAM).
* SRAM is split up into three blocks:
*
* 1) 128Kb of DTCM SRM beginning at address 0x2000:0000
* 2) 368Kb of SRAM1 beginning at address 0x2002:0000
* 3) 16Kb 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.

* 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/stm32f769i-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

* Name: board_app_initialize
*
* Description:
* Perform application specific initialization. This function is never
* called directly from application code, but only indirectly via the
* (non-standard) boardctl() interface using the command BOARDIOC_INIT.
*
* Input Parameters:
* arg - The boardctl() argument is passed to the board_app_initialize()
* implementation without modification. The argument has no
* meaning to NuttX; the meaning of the argument is a contract
* between the board-specific initalization logic and the
* matching application logic. The value cold be such things as a
* mode enumeration value, a set of DIP switch switch settings, a
* pointer to configuration data read from a file or serial FLASH,
* or whatever you would like to do with it. Every implementation
* should accept zero/NULL as a default configuration.
*
* Returned Value:
* Zero (OK) is returned on success; a negated errno value is returned on
* any failure to indicate the nature of the failure.

*
* 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).

* Name: stm32_spi1cmddata
*
* Description:
* Set or clear the SH1101A A0 or SD1306 D/C n bit to select data (true)
* or command (false). This function must be provided by platform-specific
* logic. This is an implementation of the cmddata method of the SPI
* interface defined by struct spi_ops_s (see include/nuttx/spi/spi.h).
*
* Input Parameters:
*
* spi - SPI device that controls the bus the device that requires the CMD/
* DATA selection.
* devid - If there are multiple devices on the bus, this selects which one
* to select cmd or data. NOTE: This design restricts, for example,
* one one SPI display per SPI bus.
* cmd - true: select command; false: select data
*
* Returned Value:
* None
