First run "make upload" - error

/home/midv/Arduino/hardware/tools/arm-none-eabi-gcc/bin/arm-none-eabi-ar rcs /home/midv/Arduino/examples/01.Basics/Blink/build/core.a /home/midv/Arduino/examples/01.Basics/Blink/build/core/cxxabi-compat.cpp.o
/home/midv/Arduino/hardware/tools/arm-none-eabi-gcc/bin/arm-none-eabi-ar: /home/midv/Arduino/examples/01.Basics/Blink/build/core/cxxabi-compat.cpp.o: No such file or directory

Second run "make upload" - no error, but
/home/midv/Arduino/hardware/tools/bossac -U false -e -w -v -b /home/midv/Arduino/examples/01.Basics/Blink/build/Blink.bin -R

Sorry for being extremely late, but could you try the change in #3 and see if it works for you?
