QNX GDB not working

Using QtCreator 7 (free version, GDB 7.12.0) I was able to debug my Qt application for QNX (7.1) on a remote iMX6 target.
After updating QtCreator to version 12.0.2, the same application cannot be debugged on the same target (I have noticed that in the new version is used ssh to run the program).
Analyzing the active processes on the target, I noticed that the process pdebug was running, but it was not working with my application.

Do you need "set solib-search-path" or "set sysroot"?15:52:11: User requested stop. Shutting down...
