Interface Usage
If you are using the CM5 Kit for the first time, please familiarize yourself with the hardware interfaces of each product, which will help you better understand the following content.
Debugging Serial Port
Connect the USB to TTL serial cable as shown below:
| CM5-IO | Connect | Serial Module |
|---|---|---|
| GND (pin 6) | ---> | GND |
| TX (pin 8) | ---> | RX |
| RX (pin 10) | ---> | TX |
Ethernet Port
- First, insert one end of the Ethernet cable into the CM5 Kit's Ethernet port, and connect the other end to the router, ensuring that the network is functioning properly.
- After the system starts, an IP address will be automatically assigned to the Ethernet card via DHCP, with no additional configuration needed.
- To view the IP address in the Linux system on the CM5 Kit, use the following command:
root@armsom-cm5:/# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

link/ether ce:64:1a:33:b5:40 brd ff:ff:ff:ff:ff:ff
After the CM5 Kit starts up, there are three ways to check the IP address:
- Connect an HDMI monitor, log into the system, and use the terminal to enter the
ip acommand to check the IP address. - Connect a [debug serial port](#Debugging Serial Port) and use the terminal to enter the
ip acommand to check the IP address. - If you do not have a debug serial port or an HDMI monitor, you can also check the IP address of the CM5 Kit's Ethernet port through the router's management interface. However, sometimes the IP address may not be visible on the router. If the IP address is not visible, troubleshoot as follows:
- First, check if the Linux system has started normally. If the green light on the CM5 Kit is steady, it has generally started correctly.
- Check if the Ethernet cable is securely connected, or try a different cable.
- Try using a different router, as issues have been encountered where routers cannot properly assign IP addresses or the assigned IP address does not show up on the router.
- If no other router is available, you will need to connect an HDMI monitor or use a debug serial port to check the IP address.
Note that DHCP automatic IP assignment on the CM5 Kit does not require any configuration.
- Use the
pingtool to check network connectivity.
The command to test network connectivity is shown below. You can interrupt the ping command by pressing Ctrl+C.

The CM5 Kit supports resolutions up to 2K@60Hz.
- Connect the ribbon cable as shown in the image below:
- Configuring a 10.1-inch MIPI LCD screen:
The Linux image does not enable the MIPI LCD screen configuration by default. To use the MIPI LCD screen, you need to enable it manually.
Use
nanoto open the/boot/armbianEnv.txtfile:
sudo nano /boot/armbianEnv.txt
- Find or add the "overlays=" keyword in the file.
// Choose one based on the product you have
overlays=armsom-cm5-io-display-10hd // cm5-kit
overlays=armsom-cm5-rpi-cm4-io-display // cm5-rpi-cm4-io
Shortcut keys: Ctrl + S to save Ctrl + X to exit
// Remount the file system
root@armsom-cm5-io:/home/armsom# sudo mount -o remount
// or
root@armsom-cm5-io:/home/armsom# sync
If you also need to use touch functionality, you will need to load the corresponding driver:
root@armsom-cm5-io:/home/armsom# insmod /usr/lib/modules/6.1.75-vendor-rk35xx/kernel/drivers/input/touchscreen/gt9xx/goodix_gt9xx.ko
Reboot the device to apply the Overlays settings and enable Display 10 HD support.

Notes
- Before handling the device, please ensure you wear an anti-static wrist strap or take electrostatic discharge measures to prevent damage to the development board.
- Assembly should be performed in an electrostatic-safe environment, avoiding operations in dry and low-humidity conditions.
- When not in use, store the device in an anti-static bag and keep it in a suitably temperature-controlled, low-humidity environment to prevent static electricity buildup.
- When handling the device, avoid friction or collisions to prevent the generation of static electricity that could cause damage.
- When holding the device, try to avoid direct contact with the chips on the mainboard to prevent static damage.
- Do not plug or unplug wires or other devices while the device is operating to avoid damage from electrical surges.
- When connecting or disconnecting the GPIO/MIPI expansion interfaces, make sure to turn off the power and disconnect the power cable to prevent damage from electrical current.
Without effective cooling measures, the surface temperature of the main chip may exceed 60 degrees. When handling the device, please avoid direct contact with the SoC and surrounding power inductors to prevent burns. Ensure that the environment is well-ventilated during operation to prevent localized heat buildup, which could lead to overheating. Additionally, do not place the device in direct sunlight. It is recommended to choose between the official cooling fan, heat sink, or third-party cooling kits based on specific usage conditions to ensure optimal cooling performance.
