I cannot get my Arduino_011 software to upload sketches or otherwise access my Arduino Diecimila USB AVR board. When attempting to upload a sketch I receive the following message:
“Serial port ‘/dev/tty.usbserial-A4001KX4’ already in use. Try quiting any programs that may be using it.”
“Couldn’t determine program size: text data bss dec hex filename
processing.app.SerialException: Serial port ‘/dev/tty.usbserial-A4001KX4’ already in use. Try quiting any programs that may be using it.
I am using OS X 10.5.2 (leopard), on a first gen MacBook Pro 17".
I have tried using other Arduino boards with no luck.
I have installed the software (Arduino 11) on my girl friend’s computer (also leopard) and communication is no problem.
So, the problem is on my computer and not with OS X 10.5.
I am pretty sure the problem lays in some conflicting drivers: I had earlier installed AVRdude and some other software (can’t remember which exactly) to get my school’s AVR board to work with my computer (which I managed). (This board: http://cm-wiki.stanford.edu/wiki/AVR#AVR_Microcontrollers)
These other drivers must be trying to grab my present Arduino and prevent the Arduino software from communicating with it. I have tried installing the most recent AVRdude software (5.5) to maybe overwrite the old drivers and get all present in a cooperative mood, and uninstalling it too (using “make clean, make install, make uninstall” etc…), with no luck. Does anyone know how I can get in to my computer’s guts and get rid of this software conflict, without reinstalling my system? or perhaps another solution that might work just as well?
