## Pre-built images
|
||||
|
||||
You can find pre-built **Armbian** images for Helios4 on our [Download](/download) page or directly on [Armbian website](https://dl.armbian.com/helios4/).
|
||||
|
||||
## How to build an image or a kernel?
|
||||
|
||||
Supported build environment is **Ubuntu Bionic 18.04 x64** ([minimal iso image](http://archive.ubuntu.com/ubuntu/dists/bionic/main/installer-amd64/current/images/netboot/mini.iso)).

The Armada 388 SoC provides several trigger options from different peripherals to wake up the system out of power save modes. Some of the options are:
|
||||
|
||||
* Wake on GPIO
|
||||
* Wake on LAN
|
||||
|
||||
Currently Helios4 uses the PHY interrupt and 'Wake on GPIO' event to implement Wake-on-LAN.
|
||||
|
||||
## Device Tree Support
|
||||
|
||||
Linux provides gpio-keys driver to handle GPIO event and can be configured as wakeup source.
|
||||
|
||||
```
|
||||
gpio-keys {
|
||||
compatible = "gpio-keys";
|
||||
pinctrl-0 = <µsom_phy0_int_pins>;
|
||||
|
||||
wol {
|
||||
label = "Wake-On-LAN";
|
||||
linux,code = <KEY_WAKEUP>;
|
||||
gpios = <&gpio0 18 GPIO_ACTIVE_LOW>;
|
||||
wakeup-source;
|
||||
};
|
||||
};
|
||||
```

|
||||
Current gpio-mvebu driver does not implement [irq_set_wake()](https://www.kernel.org/doc/html/v4.14/core-api/genericirq.html?highlight=irq_set_wake#c.irq_chip)
|
||||
to support GPIO as wakeup source and properly route it to upper interrupt controller (Arm GIC).
|
||||
|
||||
This will raise following issues:
|
||||
|
||||
- System unable to wake up from Suspend-to-RAM
|
||||
- System wake up from GPIO interrupts not defined as wakeup source
|
||||
- Kernel crash during wakeup from standby
|
||||
|
||||

|

To fix the issue, gpio-mvebu driver needs to be patched to implement [irq_set_wake()](https://www.kernel.org/doc/html/v4.14/core-api/genericirq.html?highlight=irq_set_wake#c.irq_chip)
|
||||
and only enable interrupt on GPIO defined as wakeup source.
|
||||
|
||||
Patch for Linux Kernel 4.14.x can be found [here](/files/wol/lk4.14-mvebu-gpio-add_wake_on_gpio_support.patch)
|
||||
|
||||
|
||||
## Enabling WOL
|
||||
|
||||
Enable the PHY to raise an interrupt when magic packet received :
|
||||
|
||||
```
|
||||
sudo ethtool -s eth0 wol g
|
||||
```
|
||||
|
||||
To make it permanent, create the following file */etc/systemd/system/wol@.service* and copy the following:
|
||||
|
||||
```
|
||||
[Unit]
|
||||
Description=Wake-on-LAN for %i
|
||||
Requires=network.target
|
||||
After=network.target
|
||||
|
||||
[Service]
|
||||
ExecStart=/sbin/ethtool -s %i wol g
|
||||
Type=oneshot
|
||||
|
||||
[Install]
|
||||
WantedBy=multi-user.target
|
||||
```
|
||||
|
||||
Then enable the service for **eth0**
|
||||
|
||||
```
|
||||
systemctl enable wol@eth0
|
||||
```
|
||||
|
||||
## Suspend System
|
||||
|
||||
Use **systemctl** command to put your system in suspend mode.
|
||||
|
||||
```
|
||||
sudo systemctl suspend
|
||||
```
|
||||
|
||||
!!! important
|
||||
Only execute this command after enabling WOL otherwise there is a risk that Helios4 will not wake up when receiving magic packet. More explanation regarding this issue on [here](/wol/#unexpected-packet).
|
||||
|
||||
## Wake up System
|
||||
|
||||
To wake up your suspended Helios4 you need to send it a magic packet from a machine on the same network.
|
||||
|
||||
Before putting Helios4 in suspend mode, you need to know its MAC address. Use **ip link** command. In example below the MAC address is *02:fc:e7:3d:b8:c8*.
|
||||
|
||||
```
|
||||
ip link
|
||||
|
||||
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
|
||||
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
|
||||
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 532
|
||||
link/ether 02:fc:e7:3d:b8:c8 brd ff:ff:ff:ff:ff:ff
|
||||
3: tunl0@NONE: <NOARP> mtu 1480 qdisc noop state DOWN mode DEFAULT group default qlen 1000
|
||||
link/ipip 0.0.0.0 brd 0.0.0.0
|
||||
```
|
||||
|
||||
From a Linux machine (running Debian/Ubuntu) on the same network :
|
||||
|
||||
1. Install **wakeonlan** tool
|
||||
|
||||
```
|
||||
sudo apt-get install wakeonlan
|
||||
```
|
||||
|
||||
2. Send magic packet
|
||||
|
||||
```
|
||||
sudo wakeonlan 02:fc:e7:3d:b8:c8
|
||||
```
|
||||
|
||||
You can refer to this [guide](https://www.cyberciti.biz/tips/linux-send-wake-on-lan-wol-magic-packets.html) from *cyberciti.biz*.

## Power Consumption
|

Measured using Sonoff POW R2 on AC side
|

|
||||
| Power state | Power (Watt) | Current (Ampere) | Remarks |

|---------------|---------------|------------------|---------|
|
||||
| Idle | 16.18 - 19.87 | 0.14 - 0.17 | |
|
||||
| Standby | 8.24 - 8.63 | 0.09 - 0.10 | |
|
||||
| Suspend | 7.46 - 7.71 | 0.07 - 0.08 | |
|
||||
| Halt/Shutdown | 11.95 | 0.11 | HDDs still active, fans run on full speed |
|
||||
|
||||

* Nominal Input Voltage: 220V
|
||||
* HDD: 4x WD Red 2TB (WD20EFRX)
|
||||
* [I2C OLED screen](/i2c/) attached to the systems
|
||||
* Variation of power consumption sometimes due to fluctuation of the input voltage

||||

||||
## Issues
|
||||
|
||||
### Unexpected Packet
|
||||
|
||||
The PHY INT pin is supposed to be handled by the Ethernet controller so when there is an interrupt the driver can respond and acknowledge the interrupt. Without this acknowledgment, the PHY INT pin will stay active and the PHY won't trigger another interrupt.
|
||||
|
||||
On specific case that after user enabled the WOL and magic packet received before entering suspend mode, Helios4 will not able to wake up. The reason is PHY interrupt already triggered before entering suspend mode and no other interrupt triggered during suspend mode. The Ethernet controller driver will reset PHY interrupt during resume and when enabling WOL.
|
||||
|
||||
Therefore it is advised to always enable WOL (**sudo ethtool -s eth0 wol g**) before entering suspend.
|
||||
|
||||
### Thermal
|
||||
|
||||
When system is put in suspend mode, the PWM feature controlling the fan speed is stopped. The fans will either spin at their lowest speed ([Batch 1 fan](/pwm/#old-fan-batch-1)) or stop spinning ([Batch 2 fan](/pwm/#new-fan-batch-2)). In the latest case, while this is not an issue for the SoC itself which is designed to run with passive cooling, it might have a negative impact on the HDD peripherals because the ambient temperature inside the case will rise.
|
||||
|
||||
Therefore it is advised to ensure that when system is suspended the case ambient temperature will not exceed the operating temperature your HDDs are rated for.
