Ping does not work from my iMX6-ULL EVK

[capecom]

I am unable to ping to or ping from my iMX6ULL-EVK board after booting Linux. I could, however, ping from u-boot. I turned off auto ip in the Linux kernel and configured static IP address to my EVK board [EVK-192.168.1.40, My PC-192.168.1.60, netmask 255.255.255.0]. 

I also applied the PHY driver patch per the information in the link https://community.nxp.com/docs/DOC333163 and the problem still persists.

Below is the log from my EVK console:

You may enable the desired port in /etc/network/interfaces file. You may try first with static IP by adding the information below in such file.

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

Hello Carlos,

Thanks for your quick reply.

I tried configuring my network interface as you have suggested. The problem remains. Here is my /etc/network/interfaces file:

root@imx6ull14x14evk:~# cat /etc/network/interfaces
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
auto lo
iface lo inet loopback

# Wired or wireless interfaces
auto eth1
iface eth1 inet static
address 192.168.1.40
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.60

Hi capecom,

are you using defualt device tree and all other settings?

Does ping work using eth0 port?

Hello Carlos,

I have another iMX6ULL EVK and I am able to ping to and from the second iMX6ULL EVK board from both EMAC ports. I am not sure what is going on with the first board I was using. I will check into it and post the information once I fix this issue. Thank you for your responses!
