I’m following the mbed local development tutorial (http://visualgdb.com/tutorials/arm/mbed/). I’m setting up VisualGDB, but at step 3. “New Embedded Project” there are no devices listed, and clicking “Download more devices” does nothing.
I need to install the toolchain for Nucleo F091RC.
Or, should I choose “Specify flags manually”? If so, what flags?
Most likely your firewall has blocked VisualGDB from downloading the project templates automatically.
Please try downloading them manually here: http://visualgdb.com/hwsupport/
You can install them via Tools->VisualGDB Package Manager (v5.2) or Embedded Tools Manager (v5.1).
