How to enable M2X ETH through overlays

We have already explained in the documentation how to useDevice Tree Overlays.

Enable M2X ETH Under Ubuntu

Update System:

$ sudo apt update
$ sudo apt full-upgrade
$ sudo do-fenix-full-upgrade
$ sync
$ sudo reboot

Change The Configuration Of Device Tree Overlays


khadas@khadas:~$ sudo vim /boot/enc.txt
# Device Tree Overlays
# uart3 -- Enable UART3 (uart_C, GPIO Header PIN15 & PIN16)
# pwm_f -- Enable PWM_F (GPIO Header PIN35)
# i2c3 -- Enable i2c3 (GPIO Header PIN22 & PIN23)
# spi1 -- Enable SPI1 (GPIO Header PIN15 & PIN16 & PIN35 & PIN37), pwm_f need to be removed
# os08a10 -- Enable OS08A10 Camera
# onewire -- Enable onewire bus (GPIO Header PIN15)
# disable-ts050 -- Disable TS050 LCD
# m2x-eth -- Enable M2X 100M ethernet. Note: 1G ethernet will be disabled.
# otg-device -- Enable USB OTG Device
overlays=uart3 pwm_f i2c3 os08a10

uart3 pwm_f i2c3 os08a10are enabled by default.

2、addm2x-ethtooverlaysnode to make M2X ETH enable

overlays=uart3 pwm_f i2c3 os08a10 --> overlays=uart3 pwm_f i2c3 os08a10 m2x-eth

3、save the film/boot/env.txt and reboot the board to make it available.

khadas@khadas:~$ sync
khadas@khadas:~$ sudo reboot

Check If M2X ETH Is Enable

1、whether you can get the IP addresss

khadas@Khadas:~$ ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet netmask broadcast
inet6 fe80::c531:9c16:df20:94f9 prefixlen 64 scopeid 0x20<link>
ether 02:42:82:4b:1d:2f txqueuelen 1000 (Ethernet)
RX packets 113 bytes 13320 (13.3 KB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 122 bytes 10072 (10.0 KB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
device interrupt 14

2、whether you can go online

khadas@Khadas:~$ ping
