Setup

1. CH34x USB Driver Setup

We sometimes get problem with USB driver for CH340/CH341 USB to serial converter. It can be solved by removing brltty package.

Remove brltty.

sudo apt autoremove brltty

2. Creating .desktop files for application on Linux

Some applications do not appear on application menu which can be solved by creating .desktop file. Create a <executable>.desktop files at /home/$USER/.local/share/applications. Add following informations:

[Desktop Entry]
Name=<Name>
Comment=<Content>
Exec=<path/to/executable>
Icon=<path/to/icon>
startupWMClass=<startupWMClass>

To check WMClass, run the executable directly from file. Run xprop | grep WM_CLASS on terminal. Click the executable window to get WM_CLASS message on terminal.

Some applications setup which do not appear on application menu are shown below. Update version and path correctly as your configuration.

Arduino IDE

Creat arduino-ide.desktop file in ~/.local/share/applications directory, and add the following content:

[Desktop Entry]
Name=Arduino IDE
Comment=Arduino IDE 2.3.2
Exec=/home/sagar/.arduino-ide_2.3.2_Linux_64bit/arduino-ide
Icon=/home/sagar/.arduino-ide_2.3.2_Linux_64bit/resources/app/resources/icons/512x512.png
Terminal=false
Type=Application
Categories=Development
StartupWMClass=Arduino IDE

The Arduino IDE is based on Electron (Chromium), and it needs a special helper binary called chrome-sandbox to be owned by root and have the setuid bit set.

cd /home/sagar/.arduino-ide_2.3.2_Linux_64bit/
sudo chown root:root chrome-sandbox
sudo chmod 4755 chrome-sandbox

STM32CubeMX

Create ‘STM32CubeMX.desktop’ file in ~/.local/share/applications directory, and add the following content:

[Desktop Entry]
Name=STM32CubeMX
Comment=STM32CubeMX 6.12.0
Exec=/home/sagar/STM32CubeMX/STM32CubeMX
Icon=/home/sagar/STM32CubeMX/help/STM32CubeMX.ico
Type=Application
Categories=Development
StartupWMClass=com-st-microxplorer-maingui-STM32CubeMX

Update desktop database.

update-desktop-database ~/.local/share/applications

Note

Make sure, the executable file has permission for execution. If not, you can change it as:

sudo chmod +x <path/to/executable>

1. STM32CubeProgrammer Setup

STM32Cube_Programmer_CLI is not on environment by default. So, create a symbolic link to your STM32_Programmer_CLI in ~/.local/bin.

mkdir -p ~/.local/bin # if does not exist
ln -s ~/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/STM32_Programmer_CLI ~/.local/bin/STM32_Programmer_CLI

4. Git Setup

Set username and email.

git config --global user.name "Your Name"
git config --global user.email "[email protected]"

Set default code editor.

git config --global core.editor "code --wait"

Verify configurations.

git config --list

5. SSH Setup

To push code on repository using https, you need to enter password every time. So, we use ssh for authentication.

Generate an SSH key:

ssh-keygen -t ed25519 -C "[email protected]"

Press Enter to save the key to the default location.

Add the SSH key to the agent:

eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_ed25519

See the ssh-key.

cat ~/.ssh/id_ed25519.pub

Add the ssh-key to your github account. Go to Github > Settings > SSH and GPG Keys. Add new ssh key.
