your detailed instructions are great, you should strip the libraries using the supplied strip tool prior to deploying to the target, impact follows:

very nice writeup

I can't strip this libraries now, I need some debug information to reconstruct the stack when a crash happens.

Qt creator strips the libs before pushing them to device.
