|
||||
|
||||
Serial Console
|
||||
==============
|
||||
|
||||
A `PinePhone Serial Debug Cable <https://wiki.pine64.org/index.php/PinePhone#Serial_console>`_
|
||||
is required to run NuttX on PinePhone.
|
||||
|
||||
On PinePhone, set the `Privacy Switch 6 (Headphone) <https://wiki.pine64.org/index.php/PinePhone#Privacy_switch_configuration>`_
|
||||
to **Off**.
|
||||
|
||||
Connect PinePhone to our computer with the Serial Debug Cable.
|
||||
On our computer, start a Serial Terminal and connect to the USB Serial Port
|
||||
at **115.2 kbps**.
|
||||
|
||||
NuttX will appear in the Serial Console when it boots on PinePhone.
|
||||
|
||||
ARM64 Toolchain
|
||||
===============
|
||||
|
||||
Before building NuttX for PinePhone, download the ARM64 Toolchain for
|
||||
**AArch64 Bare-Metal Target** ``aarch64-none-elf`` from
|
||||
`Arm GNU Toolchain Downloads <https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads>`_.
|
||||
(Skip the section for Beta Releases)
|
||||
|
||||
Add the downloaded toolchain ``gcc-arm-...-aarch64-none-elf/bin``
|
||||
to the ``PATH`` Environment Variable.
|
||||
|
||||
Check the ARM64 Toolchain:
|
||||
|
||||
.. code:: console
|
||||
|
||||
$ aarch64-none-elf-gcc -v
|
||||
|
||||
Building
|
||||
========
|
||||
|
||||
To build NuttX for PinePhone, :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 pinephone:nsh
|
||||
$ make
|
||||
$ cp nuttx.bin Image
|
||||
$ rm -f Image.gz
|
||||
$ gzip Image
|
||||
|
||||
This produces the file ``Image.gz``, which will be copied to PinePhone in the next step.
|
||||
|
||||
If the build fails with the error ``token "@" is not valid in preprocessor``,
|
||||
`apply this patch <https://github.com/apache/incubator-nuttx/pull/7284/commits/518b0eb31cb66f25b590ae9a79ab16c319b96b94#diff-12291efd8a0ded1bc38bad733d99e4840ae5112b465c04287f91ba5169612c73>`_
|
||||
to ``gcc-arm-none-eabi/arm-none-eabi/include/_newlib_version.h``
|
||||
in the ARM64 Toolchain.
|
||||
|
||||
Booting
|
||||
=======
|
||||
|
||||
NuttX boots on PinePhone via a microSD Card. To prepare the microSD Card, download the
|
||||
**PinePhone Jumpdrive Image** ``pine64-pinephone.img.xz`` from
|
||||
`dreemurrs-embedded/Jumpdrive <https://github.com/dreemurrs-embedded/Jumpdrive/releases>`_.
|
||||
|
||||
Write the downloaded image to a microSD Card with
|
||||
`Balena Etcher <https://www.balena.io/etcher/>`_.
|
||||
|
||||
Copy the file ``Image.gz`` from the previous section
|
||||
and overwrite the file on the microSD Card.
|
||||
|
||||
Check that PinePhone is connected to our computer via a
|
||||
`Serial Debug Cable <https://wiki.pine64.org/index.php/PinePhone#Serial_console>`_ at 115.2 kbps.
|
||||
`Privacy Switch 6 (Headphone) <https://wiki.pine64.org/index.php/PinePhone#Privacy_switch_configuration>`_
|
||||
should be set to **Off**.
|
||||
|
||||
Insert the microSD Card into PinePhone and power up PinePhone.
|
||||
NuttX boots on PinePhone and NuttShell (nsh) appears in the Serial Console.
|
||||
|
||||
To see the available commands in NuttShell:
|
||||
|
||||
.. code:: console
|
||||
|
||||
$ help
|
||||
|
||||

|
||||
==============
|
||||
|
||||
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 UART0 at 115.2 kbps.

*
|

|
||||
* arg - The boardctl() argument is passed to the board_app_initialize()
|
||||
* 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
