Ubuntu RFS problem on imx6

marktwainjr — Mon, 17 Jun 2013 11:43:30 GMT

Hello All,

I am using ubuntu_oneiric_4.0.0.tgz as ubuntu RFS to boot it using on IMX6 board using mfgtool to prepare sd card, i am getting uboot prompt where i set following bootargs to display on hdmi monitor

setenv bootargs_mmc 'setenv bootargs ${bootargs} root=/dev/mmcblk1p1 rootwait rw init=/init video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24 video=mxcfb1:off video=mxcfb2:off '

setenv bootcmd_mmc 'run bootargs_base bootargs_mmc;mmc dev 2;mmc read ${loadaddr} 0x800 0x2000;bootm'

setenv bootcmd 'run bootcmd_mmc'

saveenv

run bootcmd

Please see attached complete log

But i could not see anything on display..What am i missing here or doing incorrect?

it seems that Xorg/X11 servers are running already, What do i need to look further if i want to run OpenGL demo on ubuntu RFS.? Please see attached txt file for complete logs.

Further i tried to follow instructions in "Instructions_to_setup_X11_acceleration_on_Ubuntu.txt" in order to run GPU/OpenGL demos but due to network interface problem i am unable to download packages using apt-get and dpkg also !!.... How to i enable network support to imx6 board having above RFS?

ifconfig shows following

linaro@linaro-ubuntu-desktop:/$ ifconfig

lo Link encap:Local Loopback

inet addr:127.0.0.1 Mask:255.0.0.0

UP LOOPBACK RUNNING MTU:16436 Metric:1

RX packets:128 errors:0 dropped:0 overruns:0 frame:0

TX packets:128 errors:0 dropped:0 overruns:0 carrier:0

collisions:0 txqueuelen:0

RX bytes:9728 (9.7 KB) TX bytes:9728 (9.7 KB)

I;ve also tried

linaro@linaro-ubuntu-desktop:/$ sudo ifconfig eth0 192.168.0.200 up

SIOCSIFADDR: No such device

eth0: ERROR while getting interface flags: No such device

So any help would be really appriciated.

Thanks,

Maybe your Ethernet interface has a different name. What do you get from "ifconfig -a" ?

Hello davecbluechip,

Thanks,

linaro@linaro-ubuntu-desktop:~$ sudo ifconfig -a

linaro@linaro-ubuntu-desktop:~$ sudo ifconfig eth0 192.168.0.200 up

SIOCSIFADDR: No such device

linaro@linaro-ubuntu-desktop:~$ sudo ifconfig FEC0 192.168.0.200 up

SIOCSIFADDR: No such device

How do we get ethernet interface name ?

It looks like your Ethernet interface is not there. I had a quick look in your kernel log and I can't see the driver being initialised.

On my system, I get messages like this:

FEC Ethernet Driver

fec_enet_mii_bus: probed

They usually come after the flexcan driver, although the order is not critical.

Configure the gatewayip and the ipaddress at uboot:

gatewayip=10.112.102.254

netmask=255.255.255.0

ipaddr=10.112.102.116

Your net card is working properly ?
