boards: arm: stm32f3_seco_d23: Add SECO JUNO SBC-D23 board
Add support for SECO JUNO board embedded microcontroller STM32F302VC, designed to extend capabilities of the main processor Rockchip PX30. The microcontroller provides several interfaces, such as 2 and 4-Wire UARTs, USB, CAN, Modbus, 8-channels Timer, SPI, I2C and GPI/Os. The communication between the two processors is realized with an internal SPI line. Signed-off-by: Ettore Chimenti <ettore.chimenti@seco.com>

SECO JUNO SBC-D23 (STM32F302)
|

#############################
|
||||
|
||||
Overview
|
||||
********
|
||||
|
||||
JUNO (SBC-D23) is a Single Board Computer based on embedded Rockchip PX30
|
||||
Processor, featuring Quad-Core ARM Cortex-A35 processor. The processor
|
||||
integrates a Mali-G31 GPU with High performance dedicated 2D processor,
|
||||
supporting OpenGL ES 1.1 / 2.0 / 3.2, Vulkan 1.0, OpenCL 2.0 and Open VG 1.1.
|
||||
Embedded VPU is able to support video decoding of the most common coding
|
||||
standard (MPEG-4, H.265/HEVC, H.264, VP8, VC-1). The board is completed with up
|
||||
to 4GB LPDDR4-3200 32-bit bus memory directly soldered on board and one eMMC
|
||||
5.1 Flash Drive with up to 64GB of capacity. LVDS Single Channel interface and
|
||||
HDMI are supported. The RMII interface and Micrel KSZ8091 Ethernet Transceiver
|
||||
allow the implementation of a Fast Ethernet interface. The networking
|
||||
capabilities can be extended by WiFi+BT M.2 module and external modem module.
|
||||
The audio functionalities are managed by the AudioCodec embedded in the RK-809
|
||||
PMIC. The JUNO board is completed by a series of connectors with various
|
||||
interfaces (UART, SPI, I2C) managed by the microcontroller STM32F302VCT6.

|
||||
===========
|
||||
|
||||
SECO-D23 has 6 GPIO controllers. These controllers are
|
||||
responsible for pin muxing, input/output, pull-up, etc.
|
||||
|
||||
For mode details please refer to `SECO JUNO SBC-D23 board User Manual`_.

System Clock
|
||||
============
|
||||
|
||||
SECO SBC-D23 System Clock could be driven by internal or external
|
||||
oscillator, as well as main PLL clock. By default System clock is driven
|
||||
by PLL clock at 72 MHz, driven by an external oscillator at 8 MHz.
|
||||
|
||||
Serial Port
|
||||
===========
|
||||
|
||||
SECO SBC-D23 has up to 4 U(S)ARTs. The Zephyr console output
|
||||
is assigned to UART1. Default settings are 115200 8N1.
|
||||
In debug configuration UART1 is connected to the flashing connector CN56.
|
||||
|
||||
UART2 provides Modbus interface to connector CN28.
|
||||
UART3 provides RS-485 interface to connectors CN57 and CN48.
|
||||
In alternative config, USART2 and USART3 are exposed to connector J2.
|
||||
|
||||
UART1 (in alternate config) and UART5 are connected to CN32.
|
||||
|
||||
I2C
|
||||
===
|
||||
SECO SBC-D23 has up to 2 I2Cs. Both are present in connector CN33.
|
||||
I2C2 is available only on boards where DEBUG serial is not connected.
|
||||
|
||||
USB
|
||||
===
|
||||
SECO SBC-D23 has a USB 2.0 full-speed device interface available through
|
||||
its connector CN31.
|
||||
|
||||
CAN
|
||||
===
|
||||
SECO SBC-D23 has an onboard CAN transceiver (TJA1051T), and it is
|
||||
connected to both CN29 and CN30. PD0 is connected to EC_CAN_STBY.
|
||||
|
||||
SPI
|
||||
===
|
||||
SECO SBC-D23 has two SPI lines: SPI1 is an internal SPI line connected to the
|
||||
main processor (Rockchip PX30) and SPI2 is connected to CN39.
|
||||
|
||||
Programming and Debugging
|
||||
*************************
|
||||
|
||||
Flashing
|
||||
========
|
||||
|
||||
Applications for the ``stm32f3_seco_d23`` board configuration can be built and
|
||||
flashed in the usual way (see :ref:`build_an_application` and
|
||||
:ref:`application_run` for more details).
|
||||
|
||||
Flashing an application to SECO SBC-D23
|
||||
-------------------------------------------
|
||||
|
||||
First, connect the SECO SBC-D23 to your host computer using
|
||||
CN56 connector to an ST-Link.
|
||||
The pinout is (1-8):
|
||||
- VDD
|
||||
- UART1_TX
|
||||
- UART1_RX
|
||||
- BOOT_0
|
||||
- SWDIO_JTMS
|
||||
- SWCLK_JTCK
|
||||
- EC_RST#
|
||||
- GND
|
||||
|
||||
Then build and flash your application.
|
||||
|
||||
Here is an example for the :ref:`hello_world` application.
|
||||
|
||||
.. zephyr-app-commands::
|
||||
:zephyr-app: samples/hello_world
|
||||
:board: stm32f3_seco_d23
|
||||
:goals: build flash
|
||||
|
||||
Run a serial host program to connect with your board.
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
$ minicom -D /dev/<tty device>
|
||||
|
||||
Replace <tty_device> with the port where the SBC-D23 board can be
|
||||
found.
|
||||
|
||||
You should see the following message on the console:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
Hello World! stm32f3_seco_d23
