[Buildroot] zImage corruption

[Buildroot] zImage corruption

[Will Wagner]

Hi All,

I have been happily using buildroot for a while (thanks all its a great 
tool).

However I have started seeing a problem where the linux zImage being 
built gets corrupted and does not boot.

I am building a custom arm device using initramfs. If I checkout from 
clean and build it all works great and get a working zImage that is 
~7.5MB. However if I then run make again I get a zImage file that is 
~6.5MB and does not boot.

I have compared the root filesystems before and after calling make again 
and can see no difference. I have also tried doing a dirclean on the 
kernel and rebuilding and this still leads to a corrupt zImage.

Has anyone seen this before? Can anyone suggest what could be going on?

I can supply more config info if needed.

Thanks,
Will

[Buildroot] zImage corruption

[Christian SCHWARZ]

Hey Will,

I have similar troubles related to the rootfs created by buildroot, also 
on a custom ARM11 target. In my case, the Linux kernel is not able to 
start init (errors either -2, -8 or -14). In my case I had to replace 
the bin/ and etc/ directories with ones created outside in an (older) 
busybox directory.
The image sizes created by a "make" in buildroot vary greatly, sometimes 
there are 3 - 4 MB of space left in the image, sometimes only a few 
hundred kB.

cheers,
Christian
