ARM V2M MPS2 AN386
##################
Overview
********
The ``mps2/an386`` board target is used by Zephyr applications that run on
the V2M MPS2 board. It provides support for the ARM Cortex-M4 (an386) CPU and
the following devices:
- Nested Vectored Interrupt Controller (NVIC)
- System Tick System Clock (SYSTICK)
- Cortex-M System Design Kit UART
.. image:: img/mps2.jpg
:align: center
:alt: ARM V2M MPS2
In addition to enabling actual hardware usage, this board target can
also use `FVP`_ to emulate the AN386 platform running on the MPS2+.
More information about the board can be found at the `V2M MPS2 Website`_.
The Application Note an386 can be found at `Application Note an386`_.
.. note::
This board target makes no claims about its suitability for use
with actual MPS2 hardware systems using AN386, or any other hardware
system. It has been tested on FVP.
Hardware
********
ARM V2M MPS2 provides the following hardware components:
- ARM Cortex-M4 (an386)
- ARM IoT Subsystem for Cortex-M
- Form factor: 140x120cm
- ZBTSRAM: 8MB single cycle SRAM, 16MB PSRAM
- Audio: Audio Codec
- Debug:
- ARM JTAG20 connector
- ARM parallel trace connector (MICTOR38)
- 20 pin Cortex debug connector
- 10 pin Cortex debug connector
- ILA connector for FPGA debug

Supported Features
==================
The ``mps2/an386`` board target supports the following hardware features:
+-----------+------------+-------------------------------------+
| Interface | Controller | Driver/Component |
+===========+============+=====================================+
| NVIC | on-chip | nested vector interrupt controller |
+-----------+------------+-------------------------------------+
| SYSTICK | on-chip | systick |
+-----------+------------+-------------------------------------+
| UART | on-chip | serial port-polling; |
| | | serial port-interrupt |

+-----------+------------+-------------------------------------+
Other hardware features are not currently supported by the port.
See the `V2M MPS2 Website`_ for a complete list of V2M MPS2 board hardware
features.
The default configuration can be found in
:zephyr_file:`boards/arm/mps2/mps2_an386_defconfig`
Interrupt Controller
====================
MPS2 is a Cortex-M4 based SoC and has 15 fixed exceptions and 45 IRQs.
A Cortex-M3/4-based board uses vectored exceptions. This means each exception
calls a handler directly from the vector table.
Handlers are provided for exceptions 1-6, 11-12, and 14-15. The table here
identifies the handlers used for each exception.
+------+------------+----------------+--------------------------+

Pin Mapping
===========
The ARM V2M MPS2 Board has 4 GPIO controllers. These controllers are responsible
for pin muxing, input/output, pull-up, etc.
All GPIO controller pins are exposed via the following sequence of pin numbers:
- Pins 0 - 15 are for GPIO 0
- Pins 16 - 31 are for GPIO 1
- Pins 32 - 47 are for GPIO 2
- Pins 48 - 51 are for GPIO 3

System Clock
============
The V2M MPS2 main clock is 24 MHz.
Serial Port
===========
The V2M MPS2 processor has five UARTs. Both the UARTs have only two wires for
RX/TX and no flow control (CTS/RTS) or FIFO. The Zephyr console output, by
default, is utilizing UART0.
Programming and Debugging
*************************
Flashing
========
V2M MPS2 provides:
- A USB connection to the host computer, which exposes a Mass Storage and an
USB Serial Port.
- A Serial Flash device, which implements the USB flash disk file storage.
- A physical UART connection which is relayed over interface USB Serial port.
Flashing an application to V2M MPS2

Here is an example for the :zephyr:code-sample:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: mps2/an386
:goals: build
Connect the V2M MPS2 to your host computer using the USB port and you should
see a USB connection which exposes a Mass Storage and a USB Serial Port.
Copy the generated zephyr.bin in the exposed drive.
Reset the board and you should be able to see on the corresponding Serial Port
