[Buildroot] ip: RTNETLINK answers: File exists? uclibc login:??

[Tony Mozi]

 Hi all,
I'm fighting with the buildroot and for the moment, it's the king of the ring...

Well, I want to make the cross-compilation for an ARM.
I have make 'make menuconfig', load files, ...

When I start the board, I have 2 problems :

1/ On minicom -s : 
Starting network...
ip: RTNETLINK answers: File exists 

When I write a command, like ls, there is no effect.

What does it mean?


2/ On the LCD of the board :
Welcome to Buildroot
uclibc login:

Have you got an idea?

(Sorry for the previous message without object)
BR
Tony

This isn't a problem. It occurs (I think) because there are commands in
/etc/inittab to initialise the loopback interface, which get executed
again when "ifup -a" runs from the /etc/init.d/S40network initscript.
You can ignore this error.

It means there is nothing listening for your command because...

....it looks like you are not running a getty on ttyS0 (or whatever your
console is on).

In "make menuconfig", under Target Options --> Generic serial port
config, there is the option to set the serial port to run a getty on. If
you set this properly, you should end up with a line (uncommented) in
/etc/inittab that reads:

ttyS0::respawn:/sbin/getty -L ttyS0 115200 vt100 # GENERIC_SERIAL

This line will allow you to log into the system through minicom. You
should see the same prompt there you showed above that was on the LCD.

It's OK :)
Generic serial port config was not enable.
I activated it and I changed 
ttyS0::respawn:/sbin/getty -L ttyS0 115200 vt100 # GENERIC_SERIAL
by
ttyS0::respawn:/sbin/getty -L ttyUSB0 115200 vt100 # GENERIC_SERIAL
because I use an USB to RS232 converter.

Now, when I start the UART, I receive at the end :
Welcome to Buildroot
buildroot login :

I pass the login and I have an access on the serial console.

Good job :)

Tony
