Debugging multiple binaries

In order to debug multiple binaries (typically application + bootloader) in Atollic TrueSTUDIO (Eclipse in general), add the following line at the beginning of the bootloader's GDB startup script:

add-symbol-file /tmp/arduino_build_259035/KNXduinoBlinkOverKNX.ino.elf 0x080080bc

where /tmp/arduino_build_259035/KNXduinoBlinkOverKNX.ino.elf is the path to application elf file and 0x080080bc is the base address of .text section (not the base address where .isr_vector is located), see readelf -a /tmp/arduino_build_259035/KNXduinoBlinkOverKNX.ino.elf
