Hi
Linux Mint 21.3
Have a Nano with L298N. Compiles good. When selecting Nano and Port, the Port is greyed out. Same Nano on a previous laptop worked good (Linux Mint17 I think)
How do I get the 'upload' to work?
Thanks
Charles
Is your user a member of the dialout group on the new laptop?
Hi Charles, are you comfortable in linux? Then dive into a shell, or do it anyway 
-
Check that the kernel recons the Nano and assigns a tty:
Unplug the Nano, rundmesg --follow, plug the Nano back. Did a line with /dev/ttyS* appear? Restart the IDE. Is the port available now? (End dmesg) -
Member of the right group?
Type the commandgroups. Is either dialout or uucp there? If none are, you need to add your user to the right group. Typels -l /dev/ttyS*, what group do they belong to? Now entersudo usermod -a -G <group> <yourusername>followed by your password. Restart your IDE, check available ports again.
Lets see what you find.
In addition to /dev/ttyS*, more generally it might also be /dev/ttyACM* or /dev/ttyUSB*.
So unplug the device, run
ls /dev/tty*
in a terminal and note what is listed. Then plug in the device, wait a few seconds, and do it again; is anything new on the list? Then do
ls -l /dev/tty*
to see the owner and group of that item.

That's true. I chose the ttyS* since those and the ACM and USB ones will share the same group.
Is ttyS* only for actual serial ports? Might not have one nowadays, especially on a laptop.
Yes, and it's a whole bunch (32) of them ttyS's in /dev, at least in my Manjaro install. Meanwhile the computer only got 1. 
Prolly to be on the safe side in case dude got a fat Moxa card installed.

Hi. Not making any progress yet. Have a new Nano and a new cable. Still get the 'no port provided' from Linux Mint 21.3. Will try on Linux group to find out how I get it to show. Thanks for your patience.

New Zealand in upside down land
So, dmesg showed the Nano being plugged in?
Greets NZ 
Do you get a /dev/ttyACMx or /dev/ttyUSBx when you connect the board?
Any reference to BRLTTY in dmesg output?

Do you have anything connected to the 0 & 1 pins?

Back on the Linux box: same here. And I got 64 with just the number.
A minor annoyance: they're sorted so that tty63 comes before tty7. Checking the man page, the -v (for "version") option fixes that. Also looked up the globbing rules to exclude those 96(!)
$ ls -vl /dev/tty[!0-9S]* # or [:digit:] instead of 0-9
crw------- 1 root root 5, 3 Mar 10 2025 /dev/ttyprintk
Makes it easier to see if your device is added

Of course, you need some more advanced sorting if it first will sort by letters and then by value, not numbers. Clever to find out that option -v tho. One way is to check the length, sort the shortest names by letters, then go on and sort length +1.
I've only seen ttyUSB0 or ttyACM0 so far, they are easy to spot. Only tty's that are not, are the serial ports as we concluded, without checking the kernel boot log (dmesg) you never know for sure how many serial ports are installed...
I'm lazy: I usually just want to see the latest added tty when I plug something in so I use:
ls -ltr /dev/tty*

Any help would be much appreciated. Some of the code above courtesy of Perplexity AI !!
Thankyou
Charles
Old and slow
They are the same outputs, and both shows the serial port as ttyUSB0.
Did you do step 2 in post #3?
Hi
This is what I should have posted. My bad. Seems like everything is there, but not finding the port # to use.
Thanks
Charles

I doubt you'll catch the device this way. Try what I wrote:
- Unplug the Nano.
- In a shell, run
dmesg --follow - Plug in your Nano.
- Copy the new lines from dmesg and paste here.
Hi
Just opened up project again. In: Tools "Port" I now get (have not before) : "Port/dev/ttyUSB0"
Something working at last. No t sure why. Probably after I rebooted the laptop overnight.
But when I try to upload a code I still get 'no port provided'.
How to make sure that the port is connected to the sketch for uploading.
Friday morning here. Have a good weekend.
