Does not come up as DHCP client on Ethernet on Orange Pi Zero (H2+)

probonopd opened this issue · comments

Currently it seems like one needs a serial adapter to get this to work, because the device does not come up as a DHCP client on Ethernet automatically.

Installed miZy according to https://github.com/hyphop/miZy/wiki/miZy-download-install-overlay-usage:

  • With Etcher, burned orange-pi-h2-miZy-musicbox-mpd.MMC.hybrid.8M.8192.bin to SD card
  • Booted Orange Pi Zero from SD
  • Attached serial adapter as shown here
  • sudo screen /dev/ttyUSB0 115200

Comes up with

config interface 'loopback'

        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'

Would be much better if it would come up as a DHCP client automatically. Then one would not need a serial adapter.

Note to self, for comparison under Armbian I see in dmesg:

check /etc/rc.local

/opt/eth.disable - by default eth interface is disabled ( for some
powersave) - comment this line

In orange_pi_zero_miZy-mini-turbo.MMC.hybrid.8M.8192.bin.gz it is already commented by default (I did not touch this file):

#/opt/eth.disable

## disable ipv6
#net.ipv6.disable

But when I run /opt/eth.on then Ethernet becomes active (works). Thanks for the hint!

To make the change permanent, I added /opt/eth.on in /etc/rc.local and ran overlay save -f. Now the Ethernet is available after a reboot (works).

In orange-pi-h2-miZy-musicbox-mpd.MMC.hybrid.8M.8192.bin.gz /opt/eth.disable is not commented out by default. I did so.

By the way, this is my /etc/config/network:

config interface 'loopback'
        option ifname 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'
        option dns '8.8.8.8'

config interface 'lan'
        option proto 'dhcp'
        option ifname 'eth0'

ok sure
/opt/eth.on - load sunxi_gmac & enable eth0
/opt/eth.off - unload sunxi_gmac & disable eth0

Thanks. This works for me now.
