Dynamic libraries do not work
I 've found the problem, the ramdisk used contained executables as well as dyn. libs from the mpc8260 instead of the mpc862. I don't know why the whole system came to a halt without any message but replacing the dyn. libs and executables with the correct ones solved the problem of crashing.

You are right, this gives too little info. Since the system stops without giving any data, I don't know what to attach maybe: RAM: 64 Mbyte (using a static linked busybox: activating a sh (=busybox) b ::sysinit:/bin/sh) sh: /lib/ld.so.1 help page of ld.so.1 sh: /lib/ld.so.1 --verify /bin/xxx (or just any dynamic linked library) here the system has crahed or sh: /bin/xxx here the system has crashed I have tried to step through the dynamic linking, but did not succeed til after the creation of a thread. With a dynamic linked busybox the system stops after a message such as freeing xxx kbytes (I don't know the actual number by head) When init is then called, which is a part of the busybox which is dyn. liked, it crashes.

Theo, What type of processor are you using? 8xx? Did you build a tool-chain yourself and are you perhaps using floating point?

It's really hard to give any advice with the limited data. Do you get a kernel panic? Has the kernel crashed or has it become unresponsive. Making a large number of assumptions, it sounds like you've got a kernel problem, not a dynamic linking problem. Dynamic linking is handled 100% in user space. If init crashes (or is killed) you should get a kernel panic message. The fact that you get nothing says to me that dynamic linking is simply exposing a kernel bug. A good place to start is to make sure all of memory is working. Try a simple test; allocate memory in an infinite loop and see where it breaks. Cheers, g.
