To connect the kit to Ethernet LAN, plug the Ethernet cable (included with the kit) between the J14 Ethernet connector on the HGI NAVQ+ board and an Ethernet switch (or similar) connected to your LAN. The following picture illustrates connection on the kit side:
...
When Linux boots, the Ethernet interface is enabled and configured in the default image installed to the kit. The IP address is obtained from a DHCP server. Use the following command to see the IP address that has been assigned to your kit:
| Code Block |
|---|
root@imx8mmcubeuser@imx8mpnavq:~# ifconfig eth0 eth0~$ sudo ifconfig eth1 up Link encap:Ethernet HWaddr D6:1D:22:5D:D6:B6[sudo] password for user: user@imx8mpnavq:~$ ifconfig eth1 eth1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet addr:192.168.1.16 Bcast:0.202 netmask 255.255.255.0 broadcast 192.168.10.255 Mask:255.255.255.0 inet6 addr: fe80::d41dfb68:22ff4822:fe5d:d6b6/64 Scope:Link1adf:db5d prefixlen 64 scopeid 0x20<link> ... |
At this point, you can have the full Linux TCP/IP stack enabled in Linux. To provide a most basic example of how you can use Ethernet in Linux, the following command copies a file from your Linux host to the kit via scp:
| Code Block |

$ scp tmp/target.file/bin/sh root@192.168.1.6:/tmp |
Setting Ethernet MAC in U-Boot
...
Reset the kit.
Stop at the U-Boot prompt, by hitting any key in the serial console window at the U-Boot countdown.
Run the following command to determine if a MAC PHY address has been already allocated to your kit:
Code Block u-boot=> printenv ethaddr
If this command returns a valid MAC address, all is good, you can proceed to boot to Linux at this point.
If there is no MAC PHY set up in U-Boot, perform the following commands to set up the MAC PHY in U-Boot:
Code Block u-boot=> setenv ethaddr 3C:FB:96:DC:59:7F u-boot=> saveenv
If you have several kits on your LAN, increase the last digit for each kit so the MAC addresses are all unique in your LAN.
Boot to Linux, check that the kernel makes use of the MAC PHY you have assigned to your kit:
Code Block root@imx8mmcubeuser@imx8mpnavq:~# ifconfig eth0 eth0~$ ifconfig eth1 Link encap:Ethernet HWaddr 3C:FB:96:DC:59:7Feth1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet addr:192.168.1.20 Bcast:.0.202 netmask 255.255.255.0 broadcast 192.168.1.255 Mask:255.255.255.00.255 inet6 addr: fe80::d41dfb68:22ff4822:fe5d:d6b6/64 Scope:Link1adf:db5d prefixlen 64 scopeid 0x20<link> ether e6:56:76:21:d7:ef txqueuelen 1000 (Ethernet) ...
