PINE64 Ox64
|
||||
===========
|
||||
|
||||
`Ox64 <https://wiki.pine64.org/wiki/Ox64>`_ is a RISC-V Single-Board Computer
|
||||
based on the Bouffalo Lab BL808 RISC-V SoC with C906 64-bit CPU Core and
|
||||
E907 / E902 32-bit CPU Cores supported by 64 MB of embedded PSRAM memory,
|
||||
with built-in WiFi, Bluetooth and Zigbee radio interfaces.
|
||||

|
||||
USB 2.0 Type-C port and other peripheral interfaces.
|
||||
|
||||

|
||||
|
||||

|
||||

|
||||
|
||||
Serial Console
|
||||
==============
|
||||
|
||||
A **USB Serial Adapter** that supports 2 Mbps (like `CH340G Serial Adapter <https://lupyuen.github.io/articles/ox64#test-the-usb-serial-adapter>`_)
|
||||
is required to run NuttX on Ox64.
|
||||
|
||||
Connect the USB Serial Adapter to Ox64 Serial Console at:
|
||||
|
||||
========== ========
|
||||
USB Serial Ox64 Pin
|
||||
========== ========
|
||||
TX Pin 31 (GPIO 17 / UART3 RX)
|
||||
RX Pin 32 (GPIO 16 / UART3 TX)
|
||||
GND Pin 33 (GND)
|
||||
========== ========
|
||||
|
||||
On the USB Serial Adapter, set the **Voltage Level** to 3V3.
|
||||
|
||||
Connect Ox64 to our computer with the USB Serial Adapter.
|
||||
On our computer, start a Serial Terminal and connect to the USB Serial Port
|
||||
at **2 Mbps**.
|
||||
|
||||
NuttX will appear in the Serial Console when it boots on Ox64.
|
||||
|
||||
RISC-V Toolchain
|
||||
================
|
||||
|
||||
Before building NuttX for Ox64, download the **RISC-V Toolchain riscv64-unknown-elf**
|
||||
from `SiFive RISC-V Tools <https://github.com/sifive/freedom-tools/releases/tag/v2020.12.0>`_.
|
||||
|
||||
Add the downloaded toolchain ``riscv64-unknown-elf-toolchain-.../bin``
|
||||
to the ``PATH`` Environment Variable.
|
||||
|
||||
Check the RISC-V Toolchain:
|
||||
|
||||
.. code:: console
|
||||
|
||||
$ riscv64-unknown-elf-gcc -v
|
||||
|
||||
Building
|
||||
========
|
||||
|
||||
To build NuttX for Ox64, :doc:`install the prerequisites </quickstart/install>` and
|
||||
:doc:`clone the git repositories </quickstart/install>` for ``nuttx`` and ``apps``.
|
||||
|
||||
Configure the NuttX project and build the project:
|
||||
|
||||
.. code:: console
|
||||
|
||||
$ cd nuttx
|
||||
$ tools/configure.sh ox64:nsh
|
||||
$ make
|
||||
$ riscv64-unknown-elf-objcopy -O binary nuttx nuttx.bin
|
||||
|
||||
This produces the NuttX Kernel ``nuttx.bin``. Next, build the NuttX Apps Filesystem:
|
||||
|
||||
.. code:: console
|
||||
|
||||
$ make export
|
||||
$ pushd ../apps
|
||||
$ tools/mkimport.sh -z -x ../nuttx/nuttx-export-*.tar.gz
|
||||
$ make import
|
||||
$ popd
|
||||
$ genromfs -f initrd -d ../apps/bin -V "NuttXBootVol"
|
||||
|
||||
This generates the Initial RAM Disk ``initrd``.
|
||||
|
||||
Package the NuttX Kernel and Initial RAM Disk into a NuttX Image:
|
||||
|
||||
.. code:: console
|
||||
|
||||
$ head -c 65536 /dev/zero >/tmp/nuttx.pad
|
||||
$ cat nuttx.bin /tmp/nuttx.pad initrd >Image
|
||||
|
||||
The NuttX Image ``Image`` will be copied to a microSD Card in the next step.
|
||||
|
||||
Booting
|
||||
=======
|
||||
|
||||
To boot NuttX on Ox64, flash
|
||||
`OpenSBI and U-Boot Bootloader <https://lupyuen.github.io/articles/ox64>`_ to Ox64.
|
||||
|
||||
NuttX boots on Star64 via a microSD Card. Prepare a
|
||||
`Linux microSD Card <https://lupyuen.github.io/articles/ox64>`_ for Ox64.
|
||||
|
||||
Copy the file ``Image`` from the previous section
|
||||
and overwrite the file on the microSD Card.
|
||||
|
||||
Check that Ox64 is connected to our computer via a USB Serial Adapter at 2 Mbps.
|
||||
|
||||
Insert the microSD Card into Ox64 and power up Ox64 via the Micro USB Port.
|
||||
NuttX boots on Ox64 and NuttShell (nsh) appears in the Serial Console.
|
||||
|
||||
To see the available commands in NuttShell:
|
||||
|
||||
.. code:: console
|
||||
|
||||
$ help
|
||||
|
||||
Configurations
|
||||
==============
|
||||
|
||||
nsh
|
||||
---
|
||||
|
||||
Basic configuration that runs NuttShell (nsh).
|
||||
This configuration is focused on low level, command-line driver testing.
|
||||
Built-in applications are supported, but none are enabled.
|
||||
Serial Console is enabled on UART3 at 2 Mbps.
|
||||
|
||||
