Interface Usage

If you are using ArmSoM-Sige products for the first time, please familiarize yourself with the hardware interfaces of each product to better understand the following content.

Hardware Interface	Sige7	Sige5	Sige1

Debug Serial Port

Connect the USB to TTL serial cable as follows:

armsom-sige7-debug

Sige7/5/3/1	Connection	Serial Module
GND (pin 6)	--->	GND
TX (pin 8)	--->	RX
RX (pin 10)	--->	TX

Ethernet Port

First, plug one end of the network cable into the Ethernet port of the ArmSoM-SigeX, and connect the other end to a router. Ensure that the network is functional.
After the system boots, it will automatically assign an IP address to the Ethernet port via DHCP without any additional configuration.
To check the IP address in the ArmSoM-SigeX Linux system, use the following command:

armsom@armsom-sige7:~$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: enP4p65s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether c6:9c:b0:7e:2b:1f brd ff:ff:ff:ff:ff:ff permaddr aa:a6:84:1b:0d:21
    inet 192.168.10.54/24 brd 192.168.10.255 scope global dynamic noprefixroute enP4p65s0
       valid_lft 86221sec preferred_lft 86221sec
    inet6 fe80::5bb0:d96f:926d:b334/64 scope link noprefixroute
       valid_lft forever preferred_lft forever
3: enP2p33s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
    link/ether be:ed:22:01:47:d9 brd ff:ff:ff:ff:ff:ff permaddr a2:fb:fa:79:de:fb
4: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state DORMANT group default qlen 1000
    link/ether b8:2d:28:5a:52:6a brd ff:ff:ff:ff:ff:ff

There are three ways to check the IP address of ArmSoM-SigeX after it starts:

Connect an HDMI monitor, log into the system, and use the terminal command ip a to view the IP address.
Use the debug serial port terminal and enter the ip a command to check the IP address.
If neither the debug serial port nor HDMI monitor is available, you can check the IP address of the ArmSoM-SigeX Ethernet port through the router’s management interface. However, this method may sometimes fail to display the ArmSoM-SigeX IP address. If you cannot see it, try the following troubleshooting steps:
- Check if the Linux system has started properly. If the green light on the ArmSoM-SigeX is steady, it generally means the system has booted correctly; if only the red light is on, the system has not booted properly.
- Ensure the network cable is securely connected, or try a different cable.
- Try using a different router. Common issues with routers include inability to assign IP addresses or assigning them correctly but not showing them in the router's interface.
- If no alternative router is available, use an HDMI monitor or the debug serial port to check the IP address.

tip

Note that DHCP automatically assigning an IP address to the ArmSoM-SigeX requires no additional configuration.

Use the ping tool to check network connectivity.

The command to test network connectivity is shown below. You can stop the ping command with the Ctrl+C shortcut.

WIFI

The ArmSoM-Sige series products come with an onboard WIFI module, so there's no need for external network devices. They use a standard 4th-generation antenna.

Connecting to WIFI via Command Line on Server Image

First, log in to the Linux system using one of the following methods:
- If the ArmSoM-SigeX is connected to a network cable, you can log in remotely via SSH.
- If the ArmSoM-SigeX is connected via a debug serial port, use a serial terminal to log in to the Linux system.
- If the ArmSoM-SigeX is connected to an HDMI monitor, you can log in to the Linux system via the HDMI display.

Use the nmcli dev wifi command to scan for available WIFI hotspots:

# 1. Enable WIFI
armsom@armsom-sige:/# nmcli r wifi on
# 2. Scan for WIFI
armsom@armsom-sige:/# nmcli dev wifi
# 3. Connect to a WIFI network
armsom@armsom-sige:/# nmcli dev wifi connect "wifi_name" password "wifi_password"

wifi-nmcli-scan

Use the nmcli command to connect to the scanned WIFI:
- Replace wifi_name with the name of the WIFI hotspot you want to connect to.
- Replace wifi_password with the password for the WIFI hotspot.
```
armsom@armsom-sige7:~$ nmcli dev wifi connect "ydtx_5G" password "ydtx123456"
Device 'wlan0' successfully activated with "wlan0b6d10bba-e1d5-4b6d-a17f-7d5ab44bbb6f".
```

Set the GPIO pin to output mode. The third parameter requires the wPi number corresponding to the pin.

root@armsom-sige7:~/wiring-armbian# gpio mode 2 out

Set the GPIO pin to output a low level. After setting, you can measure the voltage on the pin with a multimeter; if it reads 0V, the low level is set successfully.

root@armsom-sige7:~/wiring-armbian# gpio write 2 0

Set the GPIO pin to output a high level. After setting, you can measure the voltage on the pin with a multimeter; if it reads 3.3V, the high level is set successfully.

root@armsom-sige7:~/wiring-armbian# gpio write 2 1

The setup method for other pins is similar; just change the wPi number to the corresponding pin's number.

RGB LED

Sige features two user indicator LEDs: a green LED and a red LED.

User Green LED
Constantly indicates running kernel by default.
User Red LED Off by default, can be controlled by user.

Users can control with commands:

armsom@armsom-sige:/# sudo su  
armsom@armsom-sige:/# echo timer > /sys/class/leds/red/trigger  
armsom@armsom-sige:/# echo activity > /sys/class/leds/red/trigger

RTC

The sige features an hym8563 RTC chip.
First, insert the RTC battery using the 2-pin header to supply power to the RTC IC.
Note that we should keep the RTC battery in the RTC connector and confirm the rtc hym8563 device which has been created.

armsom@armsom-sige:/# dmesg | grep rtc  
[ 6.407133] rtc-hym8563 6-0051: rtc information is valid  
[ 6.412731] rtc-hym8563 6-0051: registered as rtc0  
[ 6.413779] rtc-hym8563 6-0051: setting system clock to 2022-06-22T01:22:26 UTC (1655860946)  

Find rtc0, then use the following commands to set system time and sync to rtc0:

armsom@armsom-sige7:/# hwclock -r  
2023-11-03 10:32:40.461910+00:00  
armsom@armsom-sige7:/# date

armsom@armsom-sige7:/# hwclock -w  
armsom@armsom-sige7:/# hwclock -r  
armsom@armsom-sige7:/# poweroff  

Turn off the RTC battery for 10+ minutes, insert the battery again and boot Sige7, and check if RTC synced with system clock:

armsom@armsom-sige7:/# hwclock -r  
2023-11-03 10:35:40.461910+00:00  
armsom@armsom-sige7:/# date

Configuring the 10.1-inch MIPI LCD screen

By default, the Linux image does not have the MIPI LCD screen configuration enabled. To use the MIPI LCD screen, you need to enable it manually.
Use nano to open the /boot/armbianEnv.txt file:

sudo nano /boot/armbianEnv.txt

In this file, find or add the keyword "overlays=".

// Choose according to your product
overlays=armsom-sige7-display-10hd // Sige7
overlays=armsom-sige5-display-10hd // Sige5
overlays=armsom-sige3-display-10hd // Sige3

Shortcut keys: Ctrl + S to save Ctrl + X to exit

After editing, restart the device to apply the Overlays settings and support Display 10 HD.

CPU/GPU/NPU/DDR

The following example uses Sige7 to illustrate how to set the fixed frequency and performance modes for CPU, GPU, NPU, and DDR.

Fixed Frequency Settings

CPU Fixed Frequency

The ArmSoM-Sige7 CPU consists of 4 A55 cores and 4 A76 cores, managed in three separate groups. The nodes are as follows:

/sys/devices/system/cpu/cpufreq/policy0: (corresponding to 4 A55: CPU0-3)
affected_cpus     cpuinfo_max_freq  cpuinfo_transition_latency  scaling_available_frequencies  scaling_cur_freq  scaling_governor  scaling_min_freq  stats
cpuinfo_cur_freq  cpuinfo_min_freq  related_cpus                scaling_available_governors    scaling_driver    scaling_max_freq  scaling_setspeed

/sys/devices/system/cpu/cpufreq/policy4: (corresponding to 2 A76: CPU4-5)
affected_cpus     cpuinfo_max_freq  cpuinfo_transition_latency  scaling_available_frequencies  scaling_cur_freq  scaling_governor  scaling_min_freq  stats
cpuinfo_cur_freq  cpuinfo_min_freq  related_cpus                scaling_available_governors    scaling_driver    scaling_max_freq  scaling_setspeed

/sys/devices/system/cpu/cpufreq/policy6: (corresponding to 2 A76: CPU6-7)
affected_cpus     cpuinfo_max_freq  cpuinfo_transition_latency  scaling_available_frequencies  scaling_cur_freq  scaling_governor  scaling_min_freq  stats
cpuinfo_cur_freq  cpuinfo_min_freq  related_cpus                scaling_available_governors    scaling_driver    scaling_max_freq  scaling_setspeed

root@armsom-sige7:/ # cat /sys/devices/system/cpu/cpufreq/policy6/scaling_available_frequencies // Get current supported CPU frequencies
408000 600000 816000 1008000 1200000 1416000 1608000 1800000 2016000 2208000 2400000 
root@armsom-sige7:/ # cat /sys/devices/system/cpu/cpufreq/policy6/scaling_available_governors // Get CPU operating modes
conservative ondemand userspace powersave performance schedutil 

The default is the automatic frequency scaling mode: schedutil (to restore, set to this mode).

Manual Fixed Frequency Settings

root@armsom-sige7:/ $ su
root@armsom-sige7:/ # echo userspace > /sys/devices/system/cpu/cpufreq/policy6/scaling_governor // Manual fixed frequency mode: userspace
root@armsom-sige7:/ # echo 2016000 > /sys/devices/system/cpu/cpufreq/policy6/scaling_setspeed // Set frequency to 2016000
root@armsom-sige7:/ # cat /sys/devices/system/cpu/cpufreq/policy6/cpuinfo_cur_freq // Verify if set successfully
2016000

The other two CPU groups can be set similarly by operating the corresponding nodes.
