Genio 520/720-EVK

This chapter describes platform-dependent information and instructions for Genio 520/720-EVK. For example, you will get different benchmark results on different platforms.

For general usage of Ethernet, such as command to configure Dynamic Host Configuration Protocol (DHCP) or static IP and so on, please refer to Ethernet chapter.

Important

All the bash commands shown here use Genio 720-EVK. For Genio 520-EVK, you can follow the same steps and change the naming term from 720 to 520.

Note

This chapter presents test results from IoT Yocto v25.1 and Genio 720-EVK.

Important

A erroneous pre-allocated MAC address was inadvertently configured in mt8189.dtsi in the IoT Yocto v25.1 release. It will be removed in the next release. Users can remove the line mac-address = [00 55 7b b5 7d f7]; from mt8189.dtsi.

Ethernet Port on Genio 520/720-EVK

Enable Ethernet Port on Genio 520/720-EVK

The system enables Ethernet by default. You can check kernel configurations for Ethernet MAC with the following command: zcat /proc/config.gz | grep DWMAC.

You will find the system has enabled the following settings.

zcat /proc/config.gz | grep DWMAC
CONFIG_DWMAC_GENERIC=y
CONFIG_DWMAC_MEDIATEK=y

You can also check kernel log with the following command: dmesg | grep dwmac to confirm it has been probed properly.

dmesg | grep dwmac
