For debugging the STM32 development board latest Eclipse with gdb connected to the gdb server running on a USB connected Segger J-Link hardware debugger is needed.

This installs documentation, a GDB server and further tools for the Segger J-Link EDU debugger. Also a udev rule for the USB debugger will be installed.
