boards/risc-v/eic7700x: Add the ESWIN EIC7700 EVB board.
ESWIN's own evaluation board for this SoC. Where the StarPro64 is a single board computer built around the chip, the EVB brings out most of the SoC's interfaces. Everything shared with the StarPro64 is already in the common directory, so this carries the board's own facts: which UART reaches which connector, which pads carry the boot straps, where its memory sits, and a configuration starting from the same place the StarPro64's does. The summary tables on sheet 3 of both boards' schematics are inherited from ESWIN's reference design and describe that design rather than either board. On this board the console is UART0 through the FT4232 bridge, UART1 goes to the M.2 socket and a header, and UART2 reaches the RS232 port. The documentation page follows the board template: a photograph, the board's features, the console and its port on the FT4232 bridge, power, the build and TFTP boot procedure, and what NuttX drives so far. Boots to an NSH prompt over UART0 with all four harts running. Assisted-by: Claude:claude-opus-5 Signed-off-by: Justin Hammond <justin@dynam.ac>

|

ESWIN EIC7700 EVB
|
||||
|
||||
The `EIC7700 EVB <https://www.eswincomputing.com/en/products/index/36.html>`_
|
||||
is ESWIN's own evaluation board for the
|
||||
:doc:`EIC7700X <../../index>` SoC. Where the
|
||||
:doc:`PINE64 StarPro64 <../starpro64/index>` is a single board computer built
|
||||
around the chip, the EVB brings out most of the SoC's interfaces, so it is the
|
||||
board to develop drivers on.
|
||||
|
||||
Features
|
||||
========
|
||||
|
||||
* ESWIN EIC7700X, 4 x RV64GC 1.4 GHz RISC-V cores
|
||||
* 16 GB LPDDR5
|
||||
* eMMC, microSD and SPI NOR flash, the last holding the boot firmware
|
||||
* 2 x Ethernet (GMAC, RGMII)
|
||||
* 2 x USB 3.0, host and device capable
|
||||
* HDMI output, with CEC
|
||||
* PCIe 3.0 slot, and two M.2 slots, for SATA and for a WiFi and Bluetooth
|
||||
module
|
||||
* USB serial console, RS232 on a DB9, and further UARTs on the headers
|
||||
* Expansion headers carrying GPIO, I2C, SPI and PWM
|
||||
* PWM fan header
|
||||
|
||||
.. warning::
|
||||
|
||||
This port is under development and drives a subset of the board.
|
||||
`Peripheral Support`_ below records what it drives.
|
||||
|
||||
Serial Console
|
||||
==============
|
||||
|
||||
The console is UART0 at **115200 8N1**. It is wired to the on-board FT4232
|
||||
USB bridge, so a single USB cable carries it and no separate USB serial
|
||||
adapter is needed. The bridge presents four ports, of which UART0 is the
|
||||
third; on Linux that is usually ``/dev/ttyUSB2``, the first of the four
|
||||
being the JTAG interface:
|
||||
|
||||
.. code:: console
|
||||
|
||||
$ screen /dev/ttyUSB2 115200
|
||||
|
||||
Buttons and LEDs
|
||||
================
|
||||
|
||||
The board has four LEDs on GPIO lines 107 to 110 and one push button, ``OK``,
|
||||
on GPIO line 6. NuttX does not drive any of them yet.
|
||||
|
||||
Power Supply
|
||||
============
|
||||
|
||||
The board is powered through its barrel jack. The core rails, including the
|
||||
NPU rail, are set by regulators on I2C bus 1, which NuttX leaves alone: the
|
||||
firmware has already configured them by the time NuttX starts, and writing to
|
||||
them changes a core voltage.
|
||||
|
||||
RISC-V Toolchain
|
||||
================
|
||||
|
||||
Install `xPack GNU RISC-V Embedded GCC (riscv-none-elf)
|
||||
<https://github.com/xpack-dev-tools/riscv-none-elf-gcc-xpack/releases>`_ and
|
||||
add its ``bin`` directory to ``PATH``, as described for the
|
||||
:doc:`PINE64 StarPro64 <../starpro64/index>`.
|
||||
|
||||
Building NuttX
|
||||
==============
|
||||
|
||||
Configure and build:
|
||||
|
||||
.. code:: console
|
||||
|
||||
$ cd nuttx
|
||||
$ tools/configure.sh eic7700-evb:nsh
|
||||
$ make
|
||||
|
||||
Then build the applications filesystem and package it with the kernel:
|
||||
|
||||
.. code:: console
|
||||
|
||||
$ make export
|
||||
$ pushd ../apps
|
||||
$ tools/mkimport.sh -z -x ../nuttx/nuttx-export-*.tar.gz
|
||||
$ make import
|
||||
$ popd
|
||||
$ boards/risc-v/eic7700x/common/tools/mkimage.sh
|
||||
|
||||
The image is the kernel, then padding, then a RAM disk holding the
|
||||
applications. Use the script rather than padding by hand: the RAM disk is
|
||||
found at run time by searching memory for its header, and that search runs
|
||||
after BSS has been cleared, so the disk has to start above ``_ebss`` or it is
|
||||
zeroed before anything looks for it. The script reads ``_ebss`` from the
|
||||
kernel and pads to suit.
|
||||
|
||||
The result is ``Image-eic7700-evb``.
|
||||
|
||||
Booting NuttX
|
||||
=============
|
||||
|
||||
The board boots over TFTP from U-Boot, as the
|
||||
:doc:`PINE64 StarPro64 <../starpro64/index>` does. Copy
|
||||
``Image-eic7700-evb`` and the device tree to the TFTP server:
|
||||
|
||||
.. code:: console
|
||||
|
||||
$ wget https://github.com/lupyuen/nuttx-starpro64/raw/refs/heads/main/eic7700-evb.dtb
|
||||
$ scp Image-eic7700-evb eic7700-evb.dtb tftpserver:/tftpfolder/
|
||||
|
||||
Interrupt U-Boot with Ctrl-C at power on and boot the image:
|
||||
|
||||
.. code:: console
|
||||
|
||||
# Change to your TFTP Server
|
||||
$ setenv tftp_server 192.168.x.x
|
||||
$ saveenv
|
||||
$ dhcp ${kernel_addr_r} ${tftp_server}:Image-eic7700-evb
|
||||
$ tftpboot ${fdt_addr_r} ${tftp_server}:eic7700-evb.dtb
|
||||
$ fdt addr ${fdt_addr_r}
|
||||
$ booti ${kernel_addr_r} - ${fdt_addr_r}
|
||||
|
||||
NuttShell appears on the console.
|
||||
|
||||
Configurations
|
||||
==============
|
||||
|
||||
.. code:: console
|
||||
|
||||
$ tools/configure.sh eic7700-evb:<config-name>
|
||||
|
||||

||||

|
||||
|
||||
NuttShell on UART0 at 115200 8N1, with the RAM disk mounted and ``/proc``
|
||||

||||
Peripheral Support

||||
