Arduino serial port COM1 problem

Question

I bought an Arduino Uno and installed Arduino IDE 1.6.5. But when I want to upload a sketch to the Arduino board I get this error:

avrdude: ser_open(): can't open device "COM1": No such file or directory
ioctl("TIOCMGET"): Inappropriate ioctl for device

I'm using Ubuntu 14.04 (Trusty Tahr) LTS.

    hakan@hakan-pc:~$ ls -l /dev/ttyUSB0
ls: /dev/ttyUSB0'e erişilemedi: Böyle bir dosya ya da dizin yok(In English: No such a file like this)

 hakan@hakan-pc:~$ ls -l /dev/ttyS0
crw-rw-rw- 1 root dialout 4, 64 Tem  8 22:40 /dev/ttyS0

While the Arduino is plugged into the computer, dmesg | tail shows:

    hakan@hakan-pc:~$ dmesg | tail

How can I solve this problem?

Solution 1

1. Connect your Arduino hardware.Open Arduino IDE.

2. Go to "Tool".

3. Go to "Port".

4. Select the port to which Arduino is connected.(If no other external drive is connected except Arduino,there will be only one port)

   This will tell Arduino IDE the port to which your hardware is connected. After that,you will be able to upload your sketch successfully

Solution 2

If you run Arduino IDE on Ubuntu (Arduino 1.5.7 and Ubuntu 14.04 in my case), most possibly you cannot upload to Arduino board, caused by the error of:

avrdude: ser_open(): can't open device "/dev/ttyUSB0": Permission denied
ioctl("TIOCMGET"): Inappropriate ioctl for device

To fix it, enter the command:

$ sudo usermod -a -G dialout <username>
$ sudo chmod a+rw /dev/ttyUSB0

Where is your user name in Ubuntu, /dev/ttyUSB0 is the detected device of your Arduino board.

First line doing add group (dialout) to username
Second line doing write and read permission to "/dev/ttyUSB0"

Solution 3

I was getting the same error on Ubuntu 14.04 with Arduino Uno. What worked for me was first selecting the appropriate port under Tools > Port and then changing the permission of the port using command like:

sudo chmod a+rw /dev/ttyUSB0

Then the error disappeared and I could upload fine.

Solution 4

I received the same message in Ubuntu 14.04 and the 1.0.5 version of the IDE.

Loading the FTDI chip D2XX drivers resolved the issue (I just downloaded and followed the README install). The serial port was available, and I was also able to successfully upload to the Arduino Uno.

Solution 5

Change in the lib/preferences.txt file:

The string from

serial.port=COM1

to

serial.port=/dev/ttyUSB0

The dmesg code does not contain the information about plugging the arduino board... please change it with the relevant one. By the way, prepending LANG=C to a command should give you error messages in English.

How are you getting COM1 on Linux. That's how Windows names

[Hakan Ormancı]

prakharsingh95 yes i know but i don't understand why seen as COM1.Anyway in /dev directory there's nothing like COMx or ttyACMx. There are only tty(x) and ttyS(x).

[Hakan Ormancı]

It's (port menu) greyed out..

[kashish]

@hakan try running arduino as root . in terminal write "sudo arduino"

[Hakan Ormancı]

@kasnish i tried but it's not worked

[Shanki Bansal]

what a simple & perfect solution!!!! Save my day. I tried out many other commands in terminal that makes no change in my progress. Thanks alot.

[kashish]

@ShankiBansal your welcome!

I had this error Caused by: jssc.SerialPortException: Port name - /dev/ttyACM0; Method name - openPort(); Exception type - Permission denied. So had to use your sudo chmod a+rw /dev/ttyACM0 magic, but it DID NOT HELP. So I had to use use this command sudo adduser <username> dialout and then logout/login to make things work
