This needs to be turned on.

I think I made some progress - see attached image.

As you can see I stepped into printf and friends.

For this to work I needed a few more things:

1) directory needs the be the same on host and target

the executable on the host:

/home/student/BBBworkspace/HelloBBBAutotooled/src/HelloBBBAutotooled

the executable on the target:

/home/student/BBBWorkspace/HelloBBBAutotooled/src/HelloBBBAutotooled

2) .gdbinit

I copied my gdbinit on the host to

/home/student/BBBworkspace/HelloBBBAutotooled/.gdbinit

that's the .gdbinit

# don't use default libs from x86/Ubuntu:
set sysroot /opt/adt-target-sysroot/beagle-bone-black-ml
set solib-absolute-prefix /opt/adt-target-sysroot/beagle-bone-black-ml
set solib-search-path  /opt/adt-target-sysroot/beagle-bone-black-ml
# point to the libraries with debug info:
set debug-file-directory
/opt/adt-target-sysroot/beagle-bone-black-ml/usr/lib/debug
# point to the source code:
set substitute-path /usr/src/debug
/opt/adt-target-sysroot/beagle-bone-black-ml/usr/src/debug
set substitute-path /
/opt/adt-target-sysroot/beagle-bone-black-ml/usr/src/debug

3) Once you enter the debug view you need to go to the gdb console and:

source /home/student/BBBworkspace/HelloBBBAutotooled/.gdbinit

This did the trick for me.
