Ubuntu 12.04 Arduino Serial Port Greyed Out
Nichole Wernett
Problem 2 : Failed to open /dev/ttyACM0 (port busy)Solution : This problem appears when serial port is busy or already occupied. So kill the busy serial port with command ---> fuser -k /dev/ttyACM0. Here replace tty port with your respective ubuntu port.
Problem 3 : Board at /dev/ttyACM0 is not availableSolution : In this case your serial port in tools menu will be greyed out. I googled a lot for this, but I none of solution worked for me. Atlast I tried different arduino board and usb connector and it was working for me. So, if you are having old arduino board (can be solved using required drivers) or defected arduino board then only this problem arises.
I am running Debian 7 (Linux Crunchbang) and wanted to use The Arduino IDE to program my Arduino UNO. To do that I installed the package arduino. When I started the Arduino I was asked to add my user to the dialout group. So I did with sudo usermod -a -G dialout .
However when I start the Arduino IDE using arduino in the commandline the IDE opens but I am not able to load my program to the Arduino. The error message is "Serial port COM1 not found. Did you select the right one from the Tools > Serial Port menu?" And when I went to select the Serial Port, the option "Tools > Serial Port" is greyed out.
sudo arduino is the only way I get the Arduino IDE working (serial port and upload) on ubuntu 12.04 (64)Indeed the serial port to use is /dev/ttyACM0 in my case too.The other two (ttyS4 and ttyS0) gave an error when trying to upload to Uno.Have fun
The following steps install the IDE and remove the error java.lang.NullPointerException thrown while loading gnu.io.RXTXCommDriver which usually comes with arduino installed with apt-get command in Ubuntu.
I had the same problem, with which I struggled for few days, reading all the blog posts, watching videos and finally after i changed my uno board, it worked perfectly well. But before I did that, there were a few things I tried, which I think also had an effect.
For a Windows solution I've found that disabling and re-enabling the Arduino in Device Manager, then restarting the Arduino IDE does the trick without fail (no unplugging necessary). Why this error occurs in the first place is beyond me. Perhaps the corresponding method for Linux will fix your problem.
Slightly related (not really), I had an issue with an AVR board a while back which was fixed by setting the device to a new COM port in the driver settings. Again, however you linux bunnies do it, I'm sure it'll be cookies and cream.
I've tried the same cable and the same arduino on another machine (running windows) and it worked there. I was on an earlier version of linux and it was working, but it stopped working once I upgraded to 22.04.
For months I had to drop and stop working on my custom made board which uses CH340N for USB-TTL.
This command "sudo apt remove brltty" has solve it.
Thank you for let out what you know.
I can now start working those boards.
Thank once more.
I just wanted to let everyone know, I had this same issue, was ready to remove brltty in Synaptics, when I saw there was an update that appeared t address this. I updated it, and my NodeMCU board came right up on port: "/dev/ttyUSB0".
I am new to Ubuntu (And I love it). I want to burn a code to my Arduino Uno. When uploading the code, there's an error message saying, Serial Port COM1 not fount found. Did you select the correct one from tools -> serial port menu?. Now, visiting the tools, I can't select serial port because it is disabled. I am attaching a screen-shot of how it looks. I have done something similar in windows. How to find the serial port on Ubuntu?
Greyed out port tends to mean you haven't set the board type first - go through the settings in arduino Tools menu & set board to 'Uno', you should see the 'port' enable & auto-fill as well, most likely.
Also either the case you can try to loon on Tools->Port if exists a port that is not a /dev/ttyS0 one. Try to play with these options. Finally by searching on dmesg you can find out which port has been located for arduno as well.
I had this same problem and struggled to fix it for a while. I tried the usual suggestions about adding myself to the dialout group and was frustrated that none of those tips helped. In the end, I realized I was using a backrev version of the Arduino IDE software, and once I upgraded, the problem went away.
In Arduino IDE the serial port is greyed out and COM 1 i shown in the windowThere is no way to communicate trough serial connection.Dont know if this is a Arduino Bugg or a bugg in Bionic Beaver.The application worked in 17.10 Artfull.
Download the latest Arduino IDE from arduino.cc, extract the archive and make install.sh executable with chmod +x install.sh or through the Permissions tab of the file's properties. After this you can run sudo ./install.sh - from a terminal that has the extracted folder as its current path - to install the Arduino IDE.This should fix your problem.
I have been trying to upload the famous Blink routine to my ESP32. The procedure has been successfully compiled but every time I try to upload the compiled code I receive the error "Serial port not selected"
Aaaaah! Now that is interesting! I set up VirtualBox just a few days ago on the Mac-Mini. I use Linux Mint (LMDE40) instead of MacOS and I had been unable to get software to run two scanners in Linux and so I setup VirtualBox to run Windows so that I could use the scanners. And yes there is a problem with connecting to the USB ports although not so difficult to overcome .
I found that Virtualbox and ESP32 IDF or VSCode were not compatible. If you have the ESP32 setup right on Linux Mint 20 or Ubuntu 20.04, you have to install python-is-python3. If you try to install Virtualbox it forces you to uninstall python-is-python3. the esptool.py use pyserial.py and they have to run with python3.
At least this is what was explained to me. And I got it working by doing this. I wanted to use Virtualbox to put my Arduino in one VM and VSCode in another VM. I also had to install the Espressif IDE so I could build CircuitPython with some special menuconfig options. All of that screwed up Arduino.
So I ended up using 2 different computers instead of VMs. I have a Raspberry Pi 4 so I can run Arduino setup of everything except ESP32. I also have it setup with another SSD to run VSCode with Pico SDK which is not compatible with PlatformIO, at least I've not been successful having both on the same system.
The solution might be a little drastic but I really didn't feel like doing the homework to sort out the path and group issues that seemed to underpin the connection to the USB bus. I installed Linux Mint 20 which is based on Ubuntu rather than pure Debian.
I then paid attention to Bill's Arduino IDE install instructions in his YouTube videos "Build a Developer's Linux Workstation" and for the ESP32: "ESP32 Getting Started". Lo and behold 'Port' in the Arduino IDE tools is no longer greyed out and /dev/ttyUSB0 can be selected. Euphoria!
Tried to compile the ubiquitous 'blink' sketch - failed because it couldn't find "Python". So I followed each of Jim's "Stuff to add to a new system..........." and bingo compilation a success and upload worked correctly. Just got to work out why the LED isn't blinking yet. But that's small beer- I hope!
Something I discovered in the last few days is getting Arduino and VSCode working with my boards in KVM-QEMU and Virtual Machine Manager. I had to abandon VIrtualbox because of the conflict between VB and the python-is-python3 package required by vscode for the ESP32.
Having successfully established everything works in Mint - Ubuntu version I decided to have another go with Mint - Debian version. I think the Debian version has an issue with which Python version you want to use. Its default is Python 2.7.
This at a guess means that pip3 pyserial installs pyserial ok but it is not seen when the arduino looks for a port using python 2,7. (As I am writing this: is there a pip2?) Your suggestion of installing python-is-python3 is the key to the solution to my original problem. I had a look at changing the default version of python in the debian setup but this is apparently fraught with its own problems: see
