Configure network in Min profile

[christophe]

Hi all,

I've a little trouble to configure network. Something i can't see goes wrong:

If i use the original sd card provided by freescale, network is correctly configurated with the following boot env:

setenv baudrate '115200'
setenv loadaddr '0x70800000'
setenv netdev 'eth0'
setenv ethprime 'FEC0'
setenv uboot 'u-boot.bin'
setenv kernel 'uImage'
setenv ethact 'FEC0'
setenv bootcd 'run bootcmd_mmc'
setenv bootargs_nfs 'setenv bootargs ${bootargs} root=/dev/nfs ip=dhcp nfsroot=${serverip}:${nfsroot},v3,tcp'
setenv bootcmd_net 'run bootargs_base bootargs_nfs; tftpboot ${loadaddr} ${kernel}; bootm'
setenv bootcmd_mmc 'run bootargs_base bootargs_mmc; mmc read ${loadaddr} 0x800 0x1800; bootm'
setenv bootargs_mmc 'set bootargs ${bootargs} root=/dev/mmcblk0p1 rw rootwait'
setenv vga 'setenv bootargs console=ttymxc0,115200 video=mxcdi1fb:GBR24,VGA-XGA di1_primary vga'
setenv bootcmd_obds 'ext2load mmc 0:1 0x70800000 /unit_tests/obds.bin; go 70800000'
setenv nfsroot '/tftpboot/rootfs'
setenv lcd 'video=mxcdi0fb:RGB24,SEIKO-WVGA di0_primary'
setenv lvds 'video=mxcdi0fb:RGB666,XGA di0_primary ldb=di0'
setenv bootcmd 'run bootcmd_mmc'
setenv bootfile 'uImage'
setenv fileaddr '70800000'
setenv netmask '255.255.255.0'
setenv hdmi 'setenv bootargs console=ttymxc0,115200 video=mxcdi0fb:RGB24,1024x768M@60 hdmi di0_primary'
setenv serverip '192.168.0.1'
setenv ipaddr '192.168.1.115'
setenv gatewayip '192.168.1.2'
setenv dnsip '194.2.0.20'
setenv bootdelay '3'
setenv bootargs_base 'set bootargs console=ttymxc0,115200 video=mxcdi0fb:RGB666,XGA di0_primary ldb=di0'
setenv bootarg_mmcset 'bootargs console=ttymxc0,115200 gpu_nommu setenv bootargs console=ttymxc0,115200 video=mxcdi0fb:RGB24,1920x1080M@60 hdmi di0_primary root=/dev/nfs ip=dhcp nfsroot=10.29.240.144:/tftpboot/rootfs,v3,tcp root=/dev/mmcblk0p1 rw'
setenv bootargs 'console=ttymxc0,115200 gpu_nommu setenv bootargs console=ttymxc0,115200 video=mxcdi0fb:RGB24,1920x1080M@60 hdmi di0_primary root=/dev/nfs ip=dhcp nfsroot=10.29.240.144:/tftpboot/rootfs,v3,tcp root=/dev/mmcblk0p1 rw rootwait'
setenv ethaddr '12:34:56:78:9a:bc'
setenv stdin 'serial'
setenv stdout 'serial'
setenv stderr 'serial'

Route command says:

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     *               255.255.255.0   U     1      0        0 eth0

default         192.168.1.2     0.0.0.0         UG    0      0        0 eth0

 and ifconfig says:

Network is working properly.

Now, if i use another sd card with a Min conf profile, configurated with the same uboot env, network is not set up at all.

route and ifconfig commands are empty.

I suppose it's the uboot env that sets up network parameters. So why the result is not the same in both cases ?

And how can i set up network in the second case ?

Thanks.

Hi! You need to enable network in system configuration and then remember set up the environment, "setenv ethaddr aa:bb:cc:dd:ee:ff' then you could start to see eth0.  I guess you forgot to enable network.

[christophe]

No, its already my own values.

The problem is, that with the same uboot env (with my own ip values), network is correctly set up with the original freescale's sd card and not set up at all with Min conf profile version built with ltib.

Provide these environment variables in the u-boot environment.

setenv serverip '192.168.0.1'
setenv ipaddr '192.168.1.115'             ///replace those values with your's
setenv gatewayip '192.168.1.2'

Default setup will have default values, replace them with yours.
