I make the pinguino board with 4550 microcontroller and bootloader v4, so i test the board in windows (7 and 8) and all its ok, but i dont use windo$ any more, i try to install and run pinguino x4 in debian wheezy (64bits) with following instruccions and dosen't work,

When pressed button "Upload", terminal show next message:

In the file "pinguino.log"  can read  "Everything is OK", try compile and upload with the next command line:

~/x.4/pinguino_start.sh -p4550 -f ~/x.4/examples/01.Basics/Blink/Blink.pde --boot boot4 -ul
