[uClibc] Arm MX-1 issue

[flobro]

(all versions of buildroot (0.9.24,25,26 and snapshot of uClibc) result
in a busybox that does not run unless it is statically linked)


I have been trying to build the "buildroot" and "toolchain" for the Moto
MX-1, and have tried all combinations that the makefile allows
(different version of uClibc, compilers, sanpshots..)

The bottom line is that after the build of buildroot, I see that busybox
will not start after init releases it's memory.

And it stops.

I rebuilt busybox as static, and IT WORKS.


I statically linked strace and here is the output when run against the
dynamic busybox..

# ./strace busybox.dyn
execve("/bin/busybox.dyn", ["busybox.dyn"], [/* 16 vars */]) = 0
old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS,
-1, 0) = 0
x40005000
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++

.....


Now the other weird thing is that the pre-built rootfs available for ARM
on the uClibc also runs without problems (uClibc 0.9.24 dated 12192003).

I have seen some related things in the list, but not on ARM, and the
pre-built works (what config was used). 

What am I messing up?

Thanks

Floyd
