+# Armbian - Helios4

-Ubuntu and Debian images for ARM based single-board computers
-https://www.armbian.com
+**This repo is only for developement of Helios4 support in Armbian Build Framework**

-## How to build my own image or kernel?
+To get latest Armbian please go to the [Official Armbian Git](https://github.com/armbian/build)

-Supported build environments:

- [Ubuntu Xenial 16.04 x64](http://archive.ubuntu.com/ubuntu/dists/xenial-updates/main/installer-amd64/current/images/netboot/mini.iso) guest inside a [VirtualBox](https://www.virtualbox.org/wiki/Downloads) or other virtualization software,
- [Ubuntu Xenial 16.04 x64](http://archive.ubuntu.com/ubuntu/dists/xenial-updates/main/installer-amd64/current/images/netboot/mini.iso) guest managed by [Vagrant](https://www.vagrantup.com/). This uses Virtualbox (as above) but does so in an easily repeatable way. Please check the [Armbian with Vagrant README](https://docs.armbian.com/Developer-Guide_Using-Vagrant/) for a quick start HOWTO,
- [Ubuntu Xenial 16.04 x64](http://archive.ubuntu.com/ubuntu/dists/xenial-updates/main/installer-amd64/current/images/netboot/mini.iso) inside a [Docker](https://www.docker.com/), [systemd-nspawn](https://www.freedesktop.org/software/systemd/man/systemd-nspawn.html) or other container environment [(example)](https://github.com/igorpecovnik/lib/pull/255#issuecomment-205045273). Building full OS images inside containers may not work, so this option is mostly for the kernel compilation,
- [Ubuntu Xenial 16.04 x64](http://archive.ubuntu.com/ubuntu/dists/xenial-updates/main/installer-amd64/current/images/netboot/mini.iso) running natively on a dedicated PC or a server (**not** recommended unless you build kernel only, for full OS images always use virtualization as outlined above),
- **20GB disk space** or more and **2GB RAM** or more available for the VM, container or native OS,
- superuser rights (configured `sudo` or root access).
-
-**Execution**
-
-	apt-get -y install git
-	git clone https://github.com/armbian/build
-	cd build
-	./compile.sh
-
-Make sure that full path to the build script does not contain spaces.
-
-You will be prompted with a selection menu for a build option, a board name, a kernel branch and an OS release. Please check the documentation for [advanced options](https://docs.armbian.com/Developer-Guide_Build-Options/) and [additional customization](https://docs.armbian.com/Developer-Guide_User-Configurations/).
-
-Build process uses caching for the compilation and the debootstrap process, so consecutive runs with similar settings will be much faster.
-

+backported from https://patchwork.kernel.org/patch/9681399/
+
+* Remove atomic PWM API portion as this is not supported on LK4.4

+Subject: libata: add ledtrig support
+
+This adds a LED trigger for each ATA port indicating disk activity.
+
+As this is needed only on specific platforms (NAS SoCs and such),
+these platforms should define ARCH_WANTS_LIBATA_LEDS if there
+are boards with LED(s) intended to indicate ATA disk activity and
+need the OS to take care of that.
+In that way, if not selected, LED trigger support not will be
+included in libata-core and both, codepaths and structures remain
+untouched.

+Subject: Initial device tree
+
+- Tested using clearfrog u-boot
+- Increase SD Card clock to 50 MHz from default 25 MHz
+- All 7 LED declared as led-gpio
+- LED1 (system) default to hearbeat
+- LED7 (USB) triggered by USB Host activity
+- GPIO23 (MPP23) declared as GPIO button
+- SPI NOR flash declared as MTD
+- Enable IO expander interrupt
+- Allocate GPIOs for fans
