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

1. 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.
2. After the system starts, an IP address will be automatically assigned to the Ethernet card via DHCP, with no additional configuration needed.
3. 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/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 noprefixroute
       valid_lft forever preferred_lft forever
2: end0: <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 192.168.10.78/24 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: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
    link/ether cc:64:1a:33:b5:40 brd ff:ff:ff:ff:ff:ff
4: wlan1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN 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 a command to check the IP address.
• Connect a [debug serial port](#Debugging Serial Port) and use the terminal to enter the ip a command 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.

tip

Note that DHCP automatic IP assignment on the CM5 Kit does not require any configuration.

4. Use the ping tool to check network connectivity.
