+
+Board information
+=================
+
+This board was release by WeAct Studio in 2020 and developed based on
+STM32H743VI microcontroller.
+
+The board features:
+ - USB-C power supply
+ - SWD connector
+ - Crystal for HS 25MHz
+ - Crystal for RTC 32.768KHz
+ - 1 user LED
+ - 1 MicroSD connector supporting 1 or 4-bit bus
+ - 1 USB 2.0 Host/Device
+ - 2 SPI Flash
+ - 1 OLED display
+ - 1 Camera
+
+Board documentation: https://github.com/WeActStudio/MiniSTM32H7xx
+
+BOARD-LED
+=========
+
+The WeAct STM32H743 has 1 software controllable LED.
+
+ ==== =====
+ LED PINS
+ ==== =====
+ E3 PE3
+ ==== =====
+
+UART/USART
+==========
+
+The WeAct STM32H743 used the USART1 for serial debug messages.

+
+/* The STM32H743VI has 2048Kb of main FLASH memory. The flash memory is
+ * partitioned into a User Flash memory and a System Flash memory. Each
+ * of these memories has two banks:
+ *
+ * 1) User Flash memory:
+ *
+ * Bank 1: Start address 0x0800:0000 to 0x080F:FFFF with 8 sectors, 128Kb
each
+ * Bank 2: Start address 0x0810:0000 to 0x081F:FFFF with 8 sectors, 128Kb
each
+ *
+ * 2) System Flash memory:
+ *
+ * Bank 1: Start address 0x1FF0:0000 to 0x1FF1:FFFF with 1 x 128Kb sector
+ * Bank 1: Start address 0x1FF4:0000 to 0x1FF5:FFFF with 1 x 128Kb sector
+ *
+ * 3) User option bytes for user configuration, only in Bank 1.
+ *
+ * In the STM32H743VI, 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 memory at 0x0800:0000
+ * 2) BOOT=1: Boot address defined by user option byte BOOT_ADD1[15:0].
+ * ST programmed value: System bootloader at 0x1FF0:0000
+ *
+ * TODO: Check next paragraph with nucleo schematics
+ *
+ * NuttX does not modify these option bytes. On the unmodified NUCLEO-H743ZI
+ * board, the BOOT0 pin is at ground so by default, the STM32 will boot
+ * to address 0x0800:0000 in FLASH.
+ *
+ * The STM32H743VI also has 1024Kb of data SRAM.
+ * SRAM is split up into several blocks and into three power domains:
+ *
+ * 1) TCM SRAMs are dedicated to the Cortex-M7 and are accessible with
+ * 0 wait states by the Cortex-M7 and by MDMA through AHBS slave bus
+ *
+ * 1.1) 128Kb of DTCM-RAM beginning at address 0x2000:0000
+ *
+ * The DTCM-RAM is organized as 2 x 64Kb DTCM-RAMs on 2 x 32 bit
+ * DTCM ports. The DTCM-RAM could be used for critical real-time
+ * data, such as interrupt service routines or stack / heap memory.
+ * Both DTCM-RAMs can be used in parallel (for load/store operations)
+ * thanks to the Cortex-M7 dual issue capability.
+ *
+ * 1.2) 64Kb of ITCM-RAM beginning at address 0x0000:0000
+ *
+ * This RAM is connected to ITCM 64-bit interface designed for
+ * execution of critical real-times routines by the CPU.
+ *
+ * 2) AXI SRAM (D1 domain) accessible by all system masters except BDMA
+ * through D1 domain AXI bus matrix
+ *
+ * 2.1) 512Kb of SRAM beginning at address 0x2400:0000
+ *
+ * 3) AHB SRAM (D2 domain) accessible by all system masters except BDMA
+ * through D2 domain AHB bus matrix
+ *
+ * 3.1) 128Kb of SRAM1 beginning at address 0x3000:0000
+ * 3.2) 128Kb of SRAM2 beginning at address 0x3002:0000
+ * 3.3) 32Kb of SRAM3 beginning at address 0x3004:0000
+ *
+ * SRAM1 - SRAM3 are one contiguous block: 288Kb at address 0x3000:0000
+ *
+ * 4) AHB SRAM (D3 domain) accessible by most of system masters
+ * through D3 domain AHB bus matrix
+ *
+ * 4.1) 64Kb of SRAM4 beginning at address 0x3800:0000
+ * 4.1) 4Kb of backup RAM beginning at address 0x3880:0000
+ *
+ * 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.

+ * Description:

+ * (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 initialization logic and the
+ * matching application logic. The value could 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.
