This is how I get gdb running, there may be (probably are) better ways:

1. Add IMAGE_INSTALL_append +=  "gdb" to the end of your local.conf to 
get gdb in the image.
2. devtool modify 'package' to modify package
3. scp 
build/workspace/sources/<package-name>/oe-workdir/packages-split/<package-name>-dbg/usr/bin/.debug/<application-name> 
onto image to get symbols.
4. gdb pacakge
5. symbol-file <file you just scpd>

Not sure about vscode usage.
