Hi!
On BF537-Stamp with uClinux 2007R1RC3 I get the following when
I try to run user space real time application. The same
happens when running latency test program:
root:/usr/xenomai/bin> ./latency -t0 -T20 -h
Jump to address 0 - 0x0fff

Call Trace:
SIGSEGV
I use Xenomai 2.3.2. cross-compiled with uclibc by running
configure -build=i686-pc-linux-gnu --host=blackfin-unknown-linux-gnu \
CC=bfin-linux-uclibc-gcc CXX=bfin-linux-uclibc-gcc AR=bfin-linux-uclibc-ar \
LD=bfin-linux-uclibc-ld --disable-shared
I tried with Xenomai version 2.3.3., but nothing changed.
Do you have any idea, what might be the problem?
Thanks,
Andras Garzo
