3 Karma: 0[add] Arduino rocks Error opening serial port '/dev/ttyUSBx' on Ubuntu Dec 03, 2008, 03:42 pm Hi!I'm suddenly having problems uploading/communicating with my Arduino
Serial Port Arduino Mac
board via the Arduino Java IDE.. The strange thing is it happened after working for 2 days straight..I was editing a program, continously uploading and testing it, when I clicked the "Serial Monitor" button so I could debug (which had worked fine just minutes ago).First I get a lot serial port arduino not found of weird char's, like you'd get trying to Serial.print a non-alphanumeric byte (although it was an int) - then, after fiddeling with the Serial rate from the IDE (while the Arduino program was still running), I got an error.Ctrl+c, ./arduino and "Upload to I/O Board"... Still get an error.I've tried rebooting Ubuntu, reinstalling the software, removing all components and reprogrammed the Blink-example with my Windows machine (which worked - so I doubt the board is damaged).Below is the full error message. I'm 100% sure the usb-device is correct.processing.app.SerialException: Error opening serial port '/dev/ttyUSB0'. at processing.app.Serial.

The serial port is detected the first time I plug in the board. As soon as I upload, I get an error saying 'Error opening Serial Port '. And then the Serial Port option is not available for some time. The error repeats the next time I try to upload.

I'm using the Arduino IDE 1.0.1 and the 64bit version of Ubuntu 12.04. This has been a reoccurring problem since 10.04 and happens to a few other programs that use a serial connection too. I have no problem getting serial data from the Arduino using Python or Screen. The Arduino IDE seems to work just fine otherwise. processing.app.SerialException: Error opening serial port '/dev/ttyACM0'. at processing.app.Serial.
