Arduino Nano upload problem

[jovosm]

After upgrade to LM21 I'm unable to upload to Arduino Nano.
Every other board work OK. Before upgrade worked just fine now both, Desktop and laptop
are unable to connect. This Nano has CH340 chip and AFAIK is supported with LM.
Never had this issue with previous updates, only after this last one.
I have tried downloading and installing drivers, adding myself to dial-out user but
nothing works. On my laptop it started working suddenly on its own and after couple hours just stopped
on its own again.
Any idea?

If you're running a newer kernel than before it's possible something has changed for the worse. That on/off behaviour sounds more like a problem with the arduino or cable.

Thank You for Your help. That fist link gave me hint when run dmsg there
was message that brltty service was holding port.
Removed it and now everything works fine.
Thank again!

Hi,
following those instructions... it didn't work for me, but I couldn't try the last part because images doesn't match final part (adding line to the daemon).

I must tell that Arduino IDE doesn't work on my LM21. But when I open a VM with LM20.3 it works fine.

Also I have not the file :

/etc/udev/rules.d/50-boards.rules

us 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 04f2:b67a Chicony Electronics Co., Ltd LG HD WebCam

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

So, I don't know how to fit the line:

ATTRS{idVendor}=="04d8", ATTRS{idProduct}=="0033", MODE="0660", GROUP="plugdev"

To my particular system. Neither if I should to.

Given some extra information:
/etc/udev/rules.d/ files contains:

/etc/udev/rules.d$ ls
40-dfuse.rules 90-extraacl.rules 98-openocd.rules 99-arduino-101.rules avrisp.rules

File 99-arduino-101.rules contains:

If that applies to you, then the line of text in that file should have your device ID as shown by lsusb, 1a86:7523.

If you'd like to create that file /etc/udev/rules.d/50-boards.rules on your PC, with your device ID, just to see if it helps:

Open a Terminal (Ctrl-Alt-T), then copy-and-paste the following long line into the Terminal window, then tap Enter...

Code: Select all

sudo tee /etc/udev/rules.d/50-boards.rules<<<"ATTRS{idVendor}==\"1a86\", ATTRS{idProduct}==\"7523\", MODE=\"0660\", GROUP=\"plugdev\""

To verify the file, and the line of text in it, copy-and-paste this Terminal command...

Code: Select all

cat /etc/udev/rules.d/50-boards.rules

The Terminal output you should see: ATTRS{idVendor}=="1a86", ATTRS{idProduct}=="7523", MODE="0660", GROUP="plugdev"


To confirm that you're a member of the "plugdev" group on your PC, copy-and-paste this...

Code: Select all

groups $USER

That command shows all the groups that you're a member of on your PC. You should see plugdev in the list.

If you don't see plugdev in that list, then add yourself to that group...

Code: Select all

sudo usermod -aG plugdev $USER

Now reboot your PC.


If all that didn't make a useful change, then you may as well remove the file that you created above:

Code: Select all

sudo rm -v /etc/udev/rules.d/50-boards.rules

Thank you for the tips, done but...
Actually it didn't work.

^CProblem uploading to board.  See https://support.arduino.cc/hc/en-us/sections/360003198300 for suggestions.

No need to mention that I tried everything explained on the links and others before this point.
I have restarted the system after changes.

Whatever... that is very strange that my VM with LM20.3 works and not here with LM21.
Also cinammon very often crash, probably another issue but seems to me that LM21 is barely stable.

[iliketrains]

Calling jovosm, still around ?

Did you see anything in dmesg trying to hi-jack your USB ? OP mentions disabling brltty but now he did this.
The same problem is mentioned in this link:
https://www.chippiko.com/ch340-dev-ttyusb-not-showing
That link also suggests downloading a module but OP makes no mention of needing to do anything of that sort.

[Popopo]

Check out if the Kernel could be responsible of the issue.
It is not.

Test: MV with LM20.3 using Kernel 5.15.0-46-generic, works fine.
Main OS: LM21 using Kernel 5.15.0-46-generic & 5.15.0-47-generic, doesn't work. So the Kernel is not responsible, it seems again more structural issue than a local problem due to one component.

Update:
Something was updated in LM21 Cinnamon and now Arduino IDE is working again.

[happnatious1]

Still not working for me.

Still not working for me too.
