Installation

Please note that use of anti-virus software or a firewall may cause issues during installation.
McAfee software in particular has been especially troublesome.
If possible, disable anti-virus and firewall software during installation.
If not, use of the Offline Installer is strongly recommended.

On Windows:

If you are using an Offline CCS Installer, the zip file in which it is
distributed must first be extracted:

1. Right-click on CCS_20.x.x.xxxxx_win64.zip and select "Extract All...".
2. Enter the directory where you wish to extract the files.
3. Click on Extract.

Once extraction has successfully completed, proceed with the installation steps below.

To install Code Composer Studio:

1. Run ccs_setup_20.x.x.xxxxx.exe.
2. Choose where you want to install.
3. Select the components you wish to install.

On OS X:

Please visit https://software-dl.ti.com/ccs/esd/documents/ccs_macos_host_support.html

The offline installer is now distributed as disk images (.dmg files)

1. Right-click on CCS_20.x.x.xxxxx_osx.dmg and select "Open”. This will open the disk image and mount it.

To install Code Composer Studio:

1. Run ccs_setup_20.x.x.xxxxx by clicking on the application in the Finder
2. Choose where you want to install.
3. Select the components you wish to install.

On Linux:

Please visit https://software-dl.ti.com/ccs/esd/documents/ccs_linux_host_support.html

before installing CCS on Linux. It contains important information on
installing CCS on different Linux distributions, including CCS dependencies that may need to be installed first.

Before installing CCS, the tarball file in which the CCS Installer is distributed must first be extracted:

untar CCS_20.x.x.xxxxx_linux-x64.tar.gz and extract all files.

e.g. tar xfz CCS_20.x.x.xxxxx_linux-x64.tar.gz

Once extraction has successfully completed, proceed with the installation steps below.

Note: To facilitate the installation of emulation drivers, it is necessary to run part of the installation process as root.
You may if you wish install all of CCS as root. However, it is preferred that you first install CCS as a normal user and then install the drivers as root.

To install Code Composer Studio as a normal user and emulation drivers as root:

1. Run ccs_setup_2x.x.x.xxxxx.run as a normal user.
2. Choose where you want to install.
3. Select the components you wish to install.
4. Navigate to directory <Install-Folder>/ccs/install_scripts.
5. As root, execute script "install_drivers.sh".

To install all of Code Composer Studio as root:

1. Run ccs_setup_2x.x.x.xxxxx.run as root.
2. Choose where you want to install.
3. Select the components you wish to install.

General Information

· New Theia-based IDE:

Simple, easy-to-use environment
Compatible with VS Code® extensions:

You may need to configure proxy settings to access open-vsx.org where Theia enabled extensions are hosted.

Source code navigation.
Debug views such as breakpoints, callstack, variables, registers, memory and graphs.
Target Configuration View
Project-less debug support
New features are being added with every release, please check What’s New section for details.

Compatibility:

Project System is fully compatible with existing Code Composer Studio projects, meaning that existing projects (or example projects in SDKs) can be imported into CCS Theia. Workspaces are not compatible.

Simply import your existing projects or examples from the SDK and get started

Debug: Project based debugging is supported by providing same single click Debug Active Project action as in CCS 12.x. Project-less debug, ability to start a debug session from target configuration file (ccxml) is supported.

Workspace: CCS v20 is using different underlying framework as such workspaces are not compatible between CCS products based on Eclipse. However, projects are fully compatible.

CCS v20 supports ability to open a folder that holds CCS Projects or open a folder where projects should reside.
Similar to VS Code, CCS v20 can open multiple distinct folders that hold projects. This is documented in VS Code as multi-root workspace. However, project names need to be unique across different folders.
