i am realtively new to the usage of arduino.
i have an arduino MEGA (atmega2560) and i tried to test an RFID shield.
for this reason i had to change the baud rate of the serial monitor.
after this i could no longer upload any sketch.
i am using linux (fedora 15) at 32bit and 64bit. so it was no matter of the computer i tried to flash the sketch.
the compiler/avr dude says:
processing.app.SerialNotFoundException: Serial port '/dev/ttyACM2' not found. Did you select the right one from the Tools > Serial Port menu? at processing.app.Serial.<init>(Serial.java:153) at processing.app.Serial.<init>(Serial.java:76) at processing.app.debug.Uploader.flushSerialBuffer(Uploader.java:75) at processing.app.debug.AvrdudeUploader.uploadViaBootloader(AvrdudeUploader.java:93) at processing.app.debug.AvrdudeUploader.uploadUsingPreferences(AvrdudeUploader.java:56) at processing.app.Sketch.upload(Sketch.java:1603) at processing.app.Sketch.exportApplet(Sketch.java:1568) at processing.app.Sketch.exportApplet(Sketch.java:1524) at processing.app.Editor$DefaultExportHandler.run(Editor.java:2320) at java.lang.Thread.run(Thread.java:679)
i had some problems with finding the USB-port but after unpluging the arduino and restarting the arduino IDE it worked, until now.
i have already read something about an equivalent problem but it did not help
at all. so i am asking you for help.
thanks for your help!
