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
2023-01-15 11:19:12 +01:00
$ tools/configure.sh pinephone:lvgl
2022-11-22 00:32:45 +01:00
$ 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 `` ,
2022-12-13 02:26:31 +01:00
`apply this patch <https://github.com/apache/nuttx/pull/7284/commits/518b0eb31cb66f25b590ae9a79ab16c319b96b94#diff-12291efd8a0ded1bc38bad733d99e4840ae5112b465c04287f91ba5169612c73> `_
2022-11-22 00:32:45 +01:00
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
2023-01-15 11:19:12 +01:00
To run the LVGL Touchscreen Demo:
.. code :: console
$ lvgldemo widgets
