Arduino Port Not detected and can not run it as root

Soheil Paper

I have two Ubuntu one is 18.04 and another is 20.04, also i have some problem with Arduino boards,i have tried this instruction(pin connections and ...): enter image description here

But, the Arduino IDE can not detect the STM32f013c8t6 board with Arduino, so i tried to find the USB connection of the port by using this post commands of its answers, as you can see below:

sudo usermod -a -G dialout $USER
 ls -al /dev/USB*
ls: cannot access '/dev/USB*': No such file or directory

And by trying some others post instructions :


lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 0bda:0821 Realtek Semiconductor Corp. 
Bus 001 Device 004: ID 0bda:0129 Realtek Semiconductor Corp. RTS5129 Card Reader Controller
Bus 001 Device 003: ID 174f:2408 Syntek 
Bus 001 Device 006: ID 0483:3748 STMicroelectronics ST-LINK/V2

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

and by trign the lsb -v -d command i get the below result:

 lsusb -v -d  0483:3748

so can not see the port connection on the Arduino which has been installed by snap as you can see below :

enter image description here

Also, tried to run Arduino as root user but i get below error:

sudo arduino

So i guess this is not working because of installing the Arduino by snap and trued to fix it by sudo snap connect arduino:removable-media command but i get the mkdir: cannot create directory '/run/user/0': Permission denied error again, so i asked here:

Update1:

Based of the first comment i tried the sudo journalctl -fand get the below results:

sudo journalctl -f

Also i have installed the last Arduino version by this link and is is running by sudo arduino command but is til have this problem!.

Update2:

It is strange i have seen the below post which is saying the ST-link V2 programmer could be fake and have some wrong pin connection, and if possible i like to ask, what would be happening if i change the 2,4,6 pins configuration based of that post? as you can see below:

enter image description here

Update 3:

I have checked the ST-Link V2 and the pins was labeled correctly. so the problem is not from the wrong st-link pins system!. Thanks.

Your guesses are wrong. `usermod` changes system files that are only consulted at `login`.

Your guesses are wrong. Watch `sudo journalctl -f` as you connect the Arduino. It's probably `/dev/ttyUSB*`.

ST-LInk may not be recognized as ttyUSB and it is normal. You have to find specific guide for setting up ST-Link on Ubuntu. As starting point you can use [this document](https://github.com/stm32duino/wiki/wiki/Upload-methods). For more reproducible results please install Arduino IDE [using ubuntu-make](https://askubuntu.com/a/1025755/66509) and remove snap version (if any).

Based ofN0rbert Comment,The problem exist by snap version of Arduino which is said here:

enter image description here

So I have done the below step:

1- I have installed the last Arduino version by this link.

2-Based of this document, I have installed the STM32CubePrg

3-Selecting the below setting and codes for test :

enter image description here

#define LED_BUILTIN PC13
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}
 
// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(2000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}

4- Switch the BOOT 0 header from the '0' position to the '1' position before connecting the FTDI board to the computer for flashing the bootloader as said on this video from this post:

enter image description hereThank.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
