[Buildroot] kernel boot problem

[Buildroot] kernel boot problem

[Sagaert Johan]

Hi
 
I receive this on the console when my system boots:

When i build the same kernel (same version ,same patches and same kernel config )
With 2011.11 : panic !
With 2010.02 : ok 

Kernel 2.6.31.9 ,build with gcc 4.5.3 

Any idea (both are build in OABI but EABI yields same problem)?

Can you compare the versions of other packages used between both
buildroot versions?
For example, busybox probably changed version. Can you try stepping back that ?

 Since the panic happens before init starts, busybox is the only package 
whose version is relevant...

 However, the /init thing was added to the skeleton since 2010.02; that
may make a difference.  Johan, do you have /init on your target?  Is it
different between the two versions?

 Arnout

[Buildroot] kernel boot problem related to GCC ?

[Sagaert Johan]

Hi Thomas 

This is wat i tried :
Rootfs build in 2010.2 with kernel build with 2011.11 : fails
Rootfs build in 2011.11 with kernel build with 2010.02 : boots

So this showed that the boot problem is not in the generated rootfs.
(in fact i also tried other busybox version with the same result )

What i found in the build directory of the kernel was a file called .missing-syscalls.d, don't know if this has something to do with
it or not.

After finding no solution i ported all my patches i used on the 2.6.31.9 kernel to the 2.6.36.1 kernel and this works fine.

I have been building and building ...and i found out that building in 2011.11 with gcc 4.5.3 fails, using gcc 4.3.6 is OK !
Strange ...i think it might something to do with the ABI..
Gone try to do a build with gcc 4.4.x just out of curiosity.

Johan

[Buildroot] kernel boot problem

[Sagaert Johan]

 
Hi 

Ok, i used the same rootfs, so i the rootfs seems ok.(i did not recompile the rootfs, just used the kernel build in buildroot
2011.11)
This shows to me that the rootfs is ok.

If you saw my other post, i dound out when uning gcc 4.53 in buildroot 2011.11 the kernel fails to boot, but with gcc 4.3.6 in
buildroot 2011.11 no problem booting.
So i did a run against gcc 4.4.6  and this one is ok too.
Strange anyway..
