IMX6ULL EVK: Ethernet problem

Hi,

I have 2 IMX6ULL EVK since few months.

I create my bsp with the followings commands:

mkdir ~/bin
curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
export PATH=~/bin:$PATH
git config --global user.name "xxxxx"    //here I put another name
git config --global user.email "xxxx@xxxx.xx"    //here I put my email address
git config --list
mkdir fsl-release-bsp
cd fsl-release-bsp
repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-4.1-krogoth
repo sync
DISTRO=fsl-imx-fb MACHINE=imx6ull14x14evk source fsl-setup-release.sh -b miprimerbsp

and  generate my images files using "bitbake core-image-minimal".

With this configuration, and without any packages more in local.conf I can ping eth0 but not eth1 (I have configured  0001-ARM-imx-imx6ul-add-PHY-KSZ8081-new-silicon-revision-.patch). To resolve that I have to add "connman" package in local.conf (I don't know why).

In the next months everything ok.

 

But now, I have generate another bsp, and with the same configuration I have the following scenario:

-I have link in eth0 (192.169.10.50) and eth1(192.169.10.51)

-If I'm connected to eth0 I can ping to 192.169.10.50 and 192.169.10.51 (It's strange that I can ping 192.169.10.51  because I don't have any bridge configured between eth0 and eth1)

-If I'm connected to eth1 cannot ping 192.169.10.50 and  192.169.10.51.

 

This happens in both EVK and in few prototypes that I have with IMX6ULL.

 

Have different mac's in both eth (configured in u-boot with setenv ethaddr and setenv eth1addr).

 

In /etc/network/interfaces I have this configuración:

/etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
# The loopback interface
auto lo
iface lo inet loopback

# Wired or wireless interfaces
auto eth0
iface eth0 inet static
address 192.169.10.50
network 192.169.10.0
netmask 255.255.255.0
broadcast 192.169.10.255
gateway 192.169.10.1

auto eth1
iface eth1 inet static
address 192.169.10.51
network 192.169.10.0
netmask 255.255.255.0
broadcast 192.169.10.255
gateway 192.169.10.1

 

Any one can help me with that?

 

Thanks.

Hello,

Yes I'm late but I think that your trouble comes from the MDIO address of your second KSZ8081

Reconfiguring network interfaces...
fec 20b4000.ethernet eth0: Freescale FEC PHY driver [Micrel KSZ8081 or KSZ8091] (mii_bus:phy_addr=20b4000.ethernet:01, irq=-1)
IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
fec 2188000.ethernet eth1: Freescale FEC PHY driver [Micrel KSZ8081 or KSZ8091] (mii_bus:phy_addr=20b4000.ethernet:02, irq=-1)
IPv6: ADDRCONF(NETDEV_UP): eth1: link is not ready

The both chip have the same address on the MDIO and only the first one responds to the driver...

Hi,

Could you give me your details steps, so I can test it on my board for you.

Have a nice day

Hi,

I have a cloud, but I'm not sure if it is that(need time to probe). When I'm starting generate my image files (few months ago) I have imx-4.1.15-2.0.0. Now I have imx-4.1.15-2.1.0. I will try generate new images files with the older one.

 

My scenario was:

-In my EVK

eth0 Link encap:Ethernet HWaddr 00:04:9F:04:B7:34

-I have an computer (ubuntu 14.04) (192.169.10.1) with an ethernet cable connected to eth0 (imx6ullevk). Here I have link (with ethtool) and from my pc I can ping to 192.169.10.100 and to 192.169.10.101

-Disconnect ethernet cable from eth0 and connected to eth1. Here I have link (but I can't ping 192.169.10.100 and 192.169.10.101).

 

I try this with another pc (windows), another evk,  and the result is the same.

 

Above was the debug that I have (search for "CRCN" to check the steps):

Hi,

I have a cloud, but I'm not sure if it is that(need time to probe). When I'm starting generate my image files (few months ago) I have imx-4.1.15-2.0.0. Now I have imx-4.1.15-2.1.0. I will try generate new images files with the older one.

My scenario was:

-In my EVK

-I have an computer (ubuntu 14.04) (192.169.10.1) with an ethernet cable connected to eth0 (imx6ullevk). Here I have link (with ethtool) and for my pc I can ping to 192.169.10.100 and to 192.169.10.101

-Disconnect ethernet cable from eth0 and connected to eth1. Here I have link (but I can ping 192.169.10.100 and 192.169.10.101.

I try this with another pc (windows), another evk,  and the result is the same.

Above was the debug that I have (search for "CRCN" to check the steps):
