Hi All,
I am trying to run valgrind on ArmV7-CA9.
I cross compile the valgrind 3.6.1 for the target Arm platform using the
following commands
$ ./configure --host=armv7-unknown-linux-gnu --prefix=/opt/valgrind
$ make
$ make install
I copied the binaries and libraries generated in the /opt/valgrind folder to
the target /opt/valgrind folder.
After copying I exported the /opt/valgrind path in the target to $PATH
I run the following command on the target machine
# valgrind -d -d -v -v --trace-flags=10000000 ls -l
I am getting segfault from the *libuClibc-0.9.30-nptl.so
*Part of the output,where the segfault is happening is pasted below

Does anyone how why the valgrind is giving segfault for *
libuClibc-0.9.30-nptl.so?*
Also does Valgrind -3.6.1 will support Arm V7 Cortex A9?
How to debug the segfault happened will running the valgrind?

Durga.
