The usual procedure to debug it is ti try to boot with init which is very simple, say, which prints "Hello world!" and sleeps for one second in a loop. When that works, build busybox with the same exact toolchain libc, options etc which were working for Hello-world class init. > This happens no matter if i try to boot from nfs or from ramdisk. > I used ramdisk, which is part of eldk package and ramdisk which > i created using bussybox in combination with Eldk libraries, > but result was almost the same.

Shared libraries are another can of worms, do not try to solve two problems at once.

You are on the right track. Find a working combination of toolchain and libc which works for simple statically linked "hello world". > Right now, i'm quite clueless, because my knowledges > ot this problematics are quie poor.
