Network management in embedded

HI,


   We are working on a product with the following network management requirement
   1. dhcp enable/disable is dynamic
   2. if dhcp is enabled, and failed, a default ip/nm/gw should be used. if dhcp is disable, the default ip should be used instead.
   3. while re-plugin the network cable, if dhcp is enabled, then dhcp client should start discovering, if failed, then default network config is used. if dhcp is not enabled , then the default network config should be used instead.

   I am using ltib-20100708, I don't see how udhcpc will fullfill the requirement. Any hints? Thanks!

Br, Chen Gang

pkgs not from internet

Hello,

I have a beginners question. I want to build u-boot, and I already have the packages I need in /opt/freescale/pkgs and I want to build u-boot from those packages. I'm having an error that seems ltib is trying to download the packages from internet. How do I tell him to use those already in my computer? Do I need to edit something in the .spec file?

My lines are below:

./ltib -m prep -p u-boot-1.1.6-mpc832x_rdb.spec 

You should not be root when running ltib, do you really
want to continue ?  y|N

1) Do not run LTIB as root (just as the message says).

2) Your .ltibrc is indicating theres a local package pool (%lpp) that
points to wwwgat0.freescale.net as well as aus1xc01.mtwk.freescale.net. 
You should remove them as you are not *inside* Motorola's network.

3) The u-boot spec file (u-boot-1.1.6-mpc832x_rdb.spec) does not exist
in the LTIB source on www.ltib.org - I assume this is a Freescale
specific LTIB world.  If so you need to contact Freescale for that
missing patch file.

Re: pkgs not from internet

Woah, solved! I made md5sum for the files by hand .. and used the correct names in the .spec file... Now, everything works.. sorry to bother!

Add Device Nodes in device_table.txt doesn't Work

Hi,
I am Using a Ltib BSP from Freescale (ltib-mpc8308erdb-20100413.iso). I have
Created a Device Node Entry in the /bin/device_table.txt File as 

mydev	c	644	0	0	41	0	-	-	-

and Followed the Description in Ltib FAQs
http://ltib.org/documentation-LtibFaq#ref_106 and Force Rebuild as 

$ ./ltib -p dev -f 

After this I can See the Entry for 'mydev' in rootfs/dev Directory in the
Host System.

But Once I Load this Image in the Target System, the /dev Directory there
don't have the Entry for 'mydev' Device.

Any Clue Why this is Not Working?

Regards
Rajaram

Possibly because you are using udev to manage your devices - startup
scripts for udev create and empty /dev and then udevd populates it based
on device kobject events from the kernel.

Problem including external libraries

Hello list,

I'm trying to build a very very simple c program:

========= main.cpp
#include <stdio.h>
#include <boost/filesystem.hpp>

int main( int argc, char* argv[] )
{
    printf("Hello world \n" );
    return 0;
}
=========

with this makefile:

========== Makefile
CROSS=arm-none-linux-gnueabi-

all: link_test
link_test: main.cpp
	$(CROSS)g++ -lboost_filesystem -o link_test main.cpp
===========

the error reported i got is:

$ make ARCH=arm CROSS_COMPILER=arm-none-linux-gnueabi- KERNELDIR=../linux
main.cpp:6:32: error: boost/filesystem.hpp: No such file or directory

My objetive is to successfully include and link the link_test with
boost_filesystem. I included the boost package with "ltib
--configure"->package list->boost.

What i'm not catching here?
And how would i do the same with cmake?

Re: Problem including external libraries

Hi Ricardo,

Take a look at the example helloworld package, which has c/cpp examples.

You can try this with:

./ltib -p helloworld -m prep           # unpack for inspection in rpm/BUILD/
./ltib -p helloworld                         # build it

Look in dist/lfs-5.1/helloworld/helloworld.spec for the build instructions.

The problem you have is that you don't need to use CROSS in ltib as 
within the build environment gcc etc is already spoofed to the cross 
compiler.

Regards, Stuart

Hi Stewart,

Removing the variable CROSS on the makefile and compiling it through
ltib *did* work.

Thanks!

Re: pkgs not from internet

Hi Érico,

Just as a note, you don't have to make the md5sum files, if they are
missing, ltib will warn you but will continue.
