Hello Valgrind team,
Any comments on the issue I presented below? I am still unable to get useful data from Valgrind on ARM.
Regards,
Raul.

Subject: [Valgrind-users] ARM - WARNING: Serious error when reading debug info
Hello valgrind team,
I want to run valgrind on a ARM platform (Cortex A9) that is running Linaro. I managed to cross-compile valgrind for ARM:
root$valgrind --version
valgrind-3.10.1
Also, I succesfully compiled a program on this platform:
root$gcc -g basicmath_large.c rad2deg.c cubic.c isqrt.c -o basic -lm
Problem is, that when I try to use valgrind I get an error:
root$valgrind --tool=callgrind ./basic > out.txt
==2405== Callgrind, a call-graph generating cache profiler
==2405== Copyright (C) 2002-2013, and GNU GPL'd, by Josef Weidendorfer et al.

root$
According the the forums, this could be because "No symbols get loaded". Is there any way to solve this issue? is there a workaround for this? Same procedure do works for me on a x86 platform running ubuntu.
Raul.
