[Buildroot] No response after "Freeing init memory"

[Zdeněk Materna]

Hello,

I have problem with init. Kernel boots ok, but after message "Freeing init
memory: 120K" there is no response (*), but system seems to be up (it
responds to ping). I tried to change init=/linuxrc to init=/hello which is
statically compiled hello world and after that I got kernel panic (**). I
double checked all configuration, but I couldn't find nothing weird. I have
Generic serial port configured and console is also configured in inittab.
All is compiled with same toolchain with EABI. Where might be problem?
Thanks for any advice.

My kernel command line: mem=64M console=ttyS0,115200 root=/dev/nfs rw
nfsroot=192.168.1.37:/home/zdenal/nfsroot/,proto=tcp ip=dhcp init=/linuxrc.

[Buildroot] No response after "Freeing init memory"

[Zdeněk Materna]

Hello!

Marek: I added user_debug=31 to kernel command line, but I think it doesn't
show any problem. Not very long so I copy it directly into e-mail.

Charles: generic console support is set to ttyS0 and correct speed (115200).
I have default inittab. I'm not very experienced in configuring inittab, but
at first look there is nothing weird.

Daniel: line ::respawn:-/bin/sh was added to /etc/inittab and it's same -
after Freeing ... is only silence.

Buildroot and kernel configs are here:
http://sestka.zlutaponorka.com/zd/configs.zip.

Aah, you have enabled sysvinit. Could you disable it, make clean &&
make, and retry ?

Busybox already contains a default init, and it's the one most of us
test and use on a daily basis.

I've written this sysvinit inittab not long ago, it was working for me,
but it definitely does not receive as much testing as the sysvinit one
gets.

Isn't the main difference just S0 vs ttyS0 from the two init files?

So, (if I'm remembering correctly) a simple test would be to change
ttyS0 to S0, right?

[Buildroot] No response after "Freeing init memory"

[Zdeněk Materna]

Hello,

at first thanks for hints.

I tried to do make clean && make without sysvinit. And it's same :-( Also
tried ttyS0/S0 in inittab... I discovered that init is writing to
/dev/console like if it's normal file. So I make /dev/console link to
/dev/ttyS0 and now it writes text to ttyS0... Grrr. What's wrong?

I'm attaching /etc/inittab, /var/log/messages and /dev/ttyS0 (with some log
in it).

Best regards,
Zdenek Materna

Here are some of first lines /var/log/messages:

[Buildroot] No response after "Freeing init memory"

[Zdeněk Materna]

Ouch, my mistake! All files in /dev are plain text... I have to mount ext2
rootfs or untar rootfs from output/images on my laptop, than share this over
nfs like rootfs for my board... I'm correct?

Yes - Like it says in the documentation:

http://buildroot.net/buildroot.html#using

* target/ which contains almost the complete root filesystem for the
  target: everything needed is present except the device files in /dev/
  (Buildroot can't create them because Buildroot doesn't run as root and
  doesn't want to run as root). Therefore, this directory should not be
  used on your target. Instead, you should use one of the images built in
  the images/ directory. If you need an extracted image of the root
  filesystem for booting over NFS, then use the tarball image generated in
  images/ and extract it as root.

I promise that I will read FAQs more carefully :-) Thanks for patience! Now
I'm able to login and work.

You mean like:  "Don't top post." and "Send e-mails to this list in 
plain text format"?  =))

[Buildroot] No response after "Freeing init memory"

[Charles Krinke]

Dear Zdenek:

Usually when the terminal is quiet (no characters) after printing "Freeing
init memory", it means the init process and its associated /etc/inittab is
not quite setup completely.

So, in looking at this, I would look at your definitions of ttyS0, the
"getty" in /etc/inittab and maybe enable generic console support in
buildroot on ttyS0.

One way to ensure a working console (since the console= paramters in
cmdline seems to work) is to add the following line into your
/etc/inittab:

::respawn:-/bin/sh

That will open up /bin/sh directly on the same console already in use
by the kernel.

Could you post your Buildroot .config and kernel .config files, and the
full kernel boot log ?

Thanks,
