Re: init (busybox) problem on OSK5912

Just want to give some updates on my case...

I run strace with the "segfaulting" program (./strace
ls -l) and here the trace I see...

--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++
Process 819 detached

... There are cases wherein the program couldn't find
the lib files it's looking for (/etc/ld.so.preload,
/usr/local/arm/3.3.2/etc/ld.so.cache) but I couldn't
find these files in the toolchain either.

... The program is also looking for the other lib
files in the v5l/, v5l/fast_mult/ folders, but
eventually find them in the /lib folder, so I'm not
sure if this might be a problem..

... Any ideas?

Thanks,

Ed
