+===================
+Arduino Portenta H7
+===================
+
+This page discusses issues unique to NuttX configurations for the
+Arduino Portenta H7 board. This port applies to all versions of
+Portenta H7:
+
+* Portenta H7
+* Portenta H7 Little
+* Portenta H7 Little Connected
+
+Features
+========
+
+Arduino Portenta H7 boards come with:
+
+* STM32H747 dual-core processor
+* 8 MB SDRAM
+* 16 MB NOR Flash
+* 10/100 Ethernet Phy
+* PMIC MC34PF1550A0EP
+* Fuel Gauge Bat MAX1726
+* USB HS
+* Secure element: NXP SE0502 (Portenta H7) or Microchip ATECC608 (H7 Little and
+ H7 Little Connected)
+* Wi-Fi/Bluetooth Module (except H7 Lite)
+* DisplayPort over USB-C (Portenta H7 only)
+
+Documentation: https://docs.arduino.cc/hardware/portenta-h7/

+Flashing
+========
+
+.. note::
+ The on-board PMIC isn't supported yet, so we rely on the Arduino bootloader.
+ DO NOT ERASE the default bootloader, or you'll brick the board!
+
+Flashing with dfu-utils
+-----------------------
+
+1. Press the reset button twice. The green LED should start flashing rapidly.
+ You can check if dfu works with the ``dfu-util -l`` command. It should
return::
+
+ Found DFU: [2341:035b] ver=0200, devnum=75, cfg=1, intf=0, path="3-6.3",
alt=3, name="@Arduino boot v.25 /0x00000000/0*4Kg",
serial="003D00473133511137323532"
+ Found DFU: [2341:035b] ver=0200, devnum=75, cfg=1, intf=0, path="3-6.3",
alt=2, name="@Ext File Flash 0MB /0x00000000/0*4Kg",
serial="003D00473133511137323532"
+ Found DFU: [2341:035b] ver=0200, devnum=75, cfg=1, intf=0, path="3-6.3",
alt=1, name="@Ext RAW Flash 16MB /0x90000000/4096*4Kg",
serial="003D00473133511137323532"
+ Found DFU: [2341:035b] ver=0200, devnum=75, cfg=1, intf=0, path="3-6.3",
alt=0, name="@Internal Flash 2MB /0x08000000/01*128Ka,15*128Kg",
serial="003D00473133511137323532"
+
+2. Flash firmware after bootloader code (offset = 0x08040000)::
+
+ dfu-util --device 0x2341:0x035b -D nuttx.bin -a0
--dfuse-address=0x08040000:leave
+
+Flashing with debugger
+----------------------
+
+To connect an external debugger to Portent H7 you need Portenta Breakout and
+20-pin MIPI connector. Another option is to solder directly to the test pins
+on the board.
+
+OpenOCD works with ``target/stm32h7x_dual_bank.cfg``.
+
+Configurations
+==============
+
+Each portenta-h7 configuration is maintained in a sub-directory and
+can be selected as follow::
+
+ tools/configure.sh portenta-h7:<subdir>
+
+Where <subdir> is one of the following:
+
+nsh_cm7
+-------
+
+Configures the NuttShell (nsh) located at apps/examples/nsh. This
+configuration enables a serial console on UART1.
+Configuration dedicated for CM7 core.
+
+jumbo_cm7
+---------
+
+This configuration enables many Apache NuttX features. This is
+mostly to help provide additional code coverage in CI, but also
+allows for user to see a wide range of features that are
+supported by the OS.
+Configuration dedicated for CM7 core.

+ * 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.
