How to use two Ethernet ports at same time on i.MX6UL

andychien — Thu, 05 Jan 2017 03:23:50 GMT

Dear Sir,

Our customer used i.MX6UL and want to run two Ethernet function, but find pads define question.

We see NXP BSP and run i.MX6UL EVK is only workable one Ethernet now.

Could you tell us how to work two Ethernet at same time on i.MX6UL?

Thanks

i.MX6UL RM pad define

i.MX6UL EVK

i.MX6UL BSP pin define ethernet phy, device tree

pinctrl_enet1: enet1grp {

Hi Andy,

The Eth1 port is not defined in /etc/network/interfaces file. Only Eth0 is defined and this is why you cannot use both. To define Eth0 please edit /etc/network/interfaces adding the following information:

For a DHCP client:

auto eth1

iface eth1 inet dhcp

For a Static IP (of course this is an example, your numbers will be different):

auto eth1

iface eth1 inet static

address 192.168.0.100

network 192.168.0.0

netmask 255.255.255.0

broadcast 192.168.0.255

gateway 192.168.0.1

Regards,
Carlos
