How to assign static IP?

cengizhanyapici — Wed, 22 Mar 2017 09:09:06 GMT

In my project I use T1024rdb-64b and QorIQ SDK 2.0.I want to assign a static ip to ethaddr0.For this purpose in /home/VIDTM/QorIQ-SDK-V2.0-20160527-yocto/sources/meta-freescale/recipes-core/init-ifupdown directory,I changed the content of init-ifupdown_%.bbappend file as the following:

FILESEXTRAPATHS_prepend := "${THISDIR}/init-ifupdown:"

In this path I have this:

[lkarakaya@glcentos7 init-ifupdown]$ ls
init-ifupdown init-ifupdown_%.bbappend
[lkarakaya@glcentos7 init-ifupdown]$ cd init-ifupdown
[lkarakaya@glcentos7 init-ifupdown]$ ls
qoriq
[lkarakaya@glcentos7 init-ifupdown]$ cd qoriq/
[lkarakaya@glcentos7 qoriq]$ ls
interfaces

and in this path I changed the content of interfaces that is in the following:

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface

auto lo

iface lo inet loopback

# Wireless interfaces

iface wlan0 inet dhcp

wireless_mode managed

wireless_essid any

wpa-driver wext

wpa-conf /etc/wpa_supplicant.conf

iface atml0 inet dhcp

# Wired or wireless interfaces

auto eth0

iface eth0 inet static

address 10.254.253.1

netmask 255.255.255.0

iface eth1 inet dhcp

# Ethernet/RNDIS gadget (g_ether)

# ... or on host side, usbnet and random hwaddr

iface usb0 inet static

address 192.168.7.2

netmask 255.255.255.0

network 192.168.7.0

gateway 192.168.7.1

# Bluetooth networking

iface bnep0 inet dhcp

Then I call the "bitbake fsl-image-core" and then I followed the "Ramdisk Deployment From TFTP" on QorIQ SDK 2.0 REC.Although image was successfully inserted the board.I can not change the ip address and it preserve it's value not assigned a static.

In addition to these,I found another path that includes recipes core that is:

/home/VIDTM/QorIQ-SDK-V2.0-20160527-yocto/sources/poky/meta/recipes-core/init-ifupdown

Which one is the true path for T1024 rdb and Why I can not change ip as I wanted?or I have some problems about my image?

After loading the core image,system works truly as in the figure:

Starting OpenBSD Secure Shell server: sshd
generating ssh RSA key...
generating ssh ECDSA key...
generating ssh DSA key...
generating ssh ED25519 key...
done.
Starting network benchmark server: netserver.
Starting system log daemon...0
Starting kernel log daemon...0
Starting internet superserver: xinetd.

QorIQ SDK (FSL Reference Distro) 2.0 t1024rdb /dev/ttyS0

t1024rdb login: root
root@t1024rdb:~# ifconfig
lo        Link encap:Local Loopback
          inet addr:127.0.0.1 Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host

Look at the following page about assigning a static IP in Yocto:

https://community.nxp.com/thread/341117

See also the following page about creation a new layer in Yocto:

https://community.nxp.com/docs/DOC-331917

There is the second method.

Change file /etc/network/interfaces in your T1024 file system.

Use the following command sequence for file changing in file system:

Add files to rootfs

Use the following command sequence for adding file to RAM disk image.

rename your RAM disk image to rootfs.ext2.gz.uboot
sudo apt-get install u-boot-tools

Following are the steps for adding files into rootfilesystem:

dd if=rootfs.ext2.gz.uboot of=rootfs.ext2.gz bs=64 skip=1

gunzip rootfs.ext2.gz

mkdir /mnt/iso_1

sudo mount -oloop rootfs.ext2 /mnt/iso_1

Now, one can copy files into appropriate location under “./mnt/iso_1” directory.

sudo umount /mnt/iso_1

gzip -9 rootfs.ext2

mkimage -A ppc -O linux -T ramdisk -C gzip -n 'rootfs.ext2.gz.uboot' -d rootfs.ext2.gz rootfs.ext2.gz.uboot

+++++++++++++++++++++++

Here are the steps for re-tailoring jffs2 based rootfs

Follow steps 1-4 as mentioned above
Execute the following command

mkfs.jffs2 -b -n -e 0x20000 --pad=0x800 -r mount1/ -o rfs.jffs2

rfs.jffs2 will be the jffs2 based file system containing the custom changes made through steps 1-4

As of now, we don't have any plans to switch to ubifs based file system

Please note that mkfs.jffs2 binary should be present on the host machine (x86, etc)

Have a great day,
Pavel Chubakov

I did the first method and create a new layer.Inside this layer,I followed https://community.nxp.com/thread/341117 as you referenced.For these,I create a new folder called recipes-core like answered in the link.And then I added an init-ifupdown folder. Inside that folder I also insert an init-ifupdown_1.0.bbappend file that contains only;

FILESEXTRAPATHS_prepend := "${THISDIR}/init-ifupdown-1.0:"

Then I put a init-ifupdown-1.0 folder that contains my updated interfaces file for yocto to include.This interface is similar to following links:https://community.nxp.com/thread/341117.

And this is the content of my new layer:

[lkarakaya@glcentos7 meta-eru]$ ls
conf COPYING.MIT README recipes-core recipes-example
[lkarakaya@glcentos7 meta-eru]$ cd recipes-core/
[lkarakaya@glcentos7 recipes-core]$ ls
init-ifupdown
[lkarakaya@glcentos7 recipes-core]$ cd init-ifupdown/
[lkarakaya@glcentos7 init-ifupdown]$ ls
init-ifupdown-1.0 init-ifupdown_1.0.bbappend
[lkarakaya@glcentos7 init-ifupdown]$ cd init-ifupdown-1.0/
[lkarakaya@glcentos7 init-ifupdown-1.0]$ ls
interfaces
[lkarakaya@glcentos7 init-ifupdown-1.0]$

Ater I competed this operation,I call bitbake fsl-image-core again and with my new image,I did "Ramdisk Deployment from TFTP" as stated "SDK 2.0".Then after the "bootm 1000000 5000000 2000000" command board is correctly started.However,when I use "ifconfig" command I see that there is no changing on the ip address.Can I do something missing in this steps.I also looked carefully to creating a new layer new layer's path is :

QorIQ-SDK-V2.0-20160527-yocto/sources/poky/scripts as stated in the previous link that you shared.

I added new layer to configuration file but Is there some configuration file for adding this recipes core?

In my default files,I already have QorIQ-SDK-V2.0-20160527-yocto/sources/meta-freescale/recipes-core/init-ifupdown in this path?Is it necessary to create a new layer?Before I asking I change the content of this .bbappend like this:

FILESEXTRAPATHS_prepend := "${THISDIR}/init-ifupdown:"

Other thing is,

$ ls
init-ifupdown init-ifupdown_%.bbappend

my folder's default name is init-ifupdown_%.bbappend and when I want to change it like init-ifupdown_1.0.bbappend and use bitbake fsl-core-image I gave some error.I think this means that recipes core is already inserted the configuration.

What can be the problem about my work?

Thanks for your answer...
