Tool/software: Code Composer Studio. Hi Guys, CCS9 won't download my code to my F28335 FLASH Memory. It WILL work if I download to RAM but I need it to download my code to FLASH and run from there. I have changed the.CMD file to include FLASHA to FLASHH banks. When I BUILD my code CCS shows that its being stored in FLASHA as I have requested.

Code Composer Studio is anintegrated development environment (IDE) that supports TI’sMicrocontroller and Embedded Processors portfolio. Code Composer Studiocomprises a suite of tools used to develop and debug embeddedapplications. It includes an optimizing C/C++ compiler, source codeeditor, project build environment, debugger, profiler, and many otherfeatures. The intuitive IDE provides a single user interface taking youthrough each step of the application development flow. Familiar toolsand interfaces allow users to get started faster than ever before. CodeComposer Studio combines the advantages of the Eclipse softwareframework with advanced embedded debug capabilities from TI resulting ina compelling feature-rich development environment for embeddeddevelopers.

More information on installation instructions as well as debug probe and device supportis available in the macOS Host Support page.

Code Composer Studio is based on the Eclipse open source software framework. Hence understanding some of the basicconcepts of Eclipse will lead to a better understanding of Code Composer Studio. Some of the more commonly referenced concepts are describedbelow.

2.2.1. Workbench¶

The Workbench refers to the main user interface. The Workbench containsall the various views and resources used for development. When theWorkbench is launched, the first dialog prompts for location ofworkspace. After the workspace location is chosen, asingle Workbench window is displayed. A Workbench window offers one ormore perspectives.

Multiple Workbench windows can be opened using the Window → NewWindow menu. While each Workbench window can differ visually(arrangement of views, toolbars and such), all windows refer to the sameworkspace and the same running instance of Code Composer Studio. If aproject is opened from one Workbench, that same project will be presentin all the Workbench windows.

2.2.2. Workspace¶

The workspace is the main working folder for Code Composer Studio. Theworkspace stores references to all projects even if the projectsthemselves do not physically reside inside the workspace folder. Thedefault location of new projects will be within the workspace folder.Once a project has been added to the workspace, it will be visible inthe Project Explorer view.

Code Composer Studio will prompt for the workspace folder location whenyou launch the application. It is possible to specify to use theselected folder as the default folder to avoid being prompted in thefuture

The workspace folder is also used to store user information such as userinterface preferences and settings.

Workspaces are user specific and are not typically shared between users.You would not check your workspace into source control to share withother team members. You would check your projects into source controland each user would have their own workspace that references theprojects.

It possible to have multiple. Only one workspace is active at a time inCode Composer Studio but you can switch workspaces using the File →Switch Workspace… menu.

2.2.3. Perspective¶

A perspective defines the layout of views, menus and toolbars in theWorkbench window. Each perspective provides a set of functionality aimedat accomplishing a specific type of task. For example, the CCS Editperspective contains views most commonly used during code development,such as the Project Explorer, Editor and Problems view. When a debugsession is started, Code Composer Studio will automatically switch tothe CCS Debug perspective. This perspective by default containsviews associated with debugging.

It is possible to manually switch between perspectives using theperspective buttons at the top right of the Workbench or by using theWindow → Perspective menu. Any changes made to a perspective will bepreserved the next time the perspective is opened. A perspective can bereset to the default arrangement via the Window -> Perspective → ResetPerspective menu. New perspectives can be created simply by saving thecurrent perspective as a new name Window → Perspective → SavePerspective As… menu.

There is a CCS Simple perspective available that can be accessedfrom the Getting Started view. This perspective is used for bothediting and debugging and has been designed to expose just the mostbasic functionality to make it easier for users who are familiar withmore simple environments.

2.2.4. View¶

Views are windows within the main Workbench window that provide visualrepresentation of information or data. The Workbench window mainlyconsists of the editor and a collection of views. Examples of some viewsare Debug, Problems, Memory Browser, Disassembly.

2.2.5. Resource¶

Resources is a collective term for a project, folder or file that existsin the Workspace.

2.2.6. Project¶

Projects typically contain folders and files. Like the workspace, aproject maps to a physical folder in the file system. The defaultlocation, when creating a new project, is in a subfolder (of the projectname) within the workspace folder. However a folder outside theworkspace can also be chosen. Once the project is created, a referenceto it will be made in the workspace and the project is now available foruse within the Workbench and visible from the Project Explorer.

Projects are either open or closed. When a project is closed, it isstill part of the workspace, but it cannot be modified by the Workbench.The resources of a closed project will not appear in the Workbench, butthe resources still reside on the local file system. Closed projectsrequire less memory and are not scanned during routine activity. Henceclosing unnecessary projects can improve performance of Code ComposerStudio. Note that closed projects will still be visible in Project Explorerso that they can easily be opened when needed.

A project becomes part of a workspace by being created in the workspaceor by being imported into the workspace.

The Project Explorer shows all projects that are part of the activeworkspace. Note that the view is mostly a representation of thefilesystem of the project folder. Hence when creating a subfolder andmoving files to that subfolder from within the Project Explorer, theactual file system is being altered. Similarly changes made to the filesystem will be reflected in the Project Explorer. Note that not allfiles that appear in the view will exist in the file system and viceversa. Linked files will appear in the view but because they arereferences and not actual copies, the references do not appear in theactual file system. The Includes folder that appears in the ProjectExplorer displays all of the include paths setup for the project and isnot a physical folder.

2.2.7. File¶

Files can either be added or linked to a project. When a file is addedto a project, the file is copied to the root location of the projectfolder. There is also the option to ‘link’ a file to a project. Thiswill simply have the project create a reference to the file instead ofcopying the file into the project folder.

There is no license fee associated with Code Composer Studio. Users arefree to download and install Code Composer Studio without having topurchase a license. The license terms for Code Composer Studio are shownat installation and available afterwards in the /doc folder.

Code Composer Studio is a suite of development tools including aneditor, project management system, compiler, debugger, profiling andvisualization tools.

2.4.1. IDE¶

IDE stands for Integrated Development Environment. It refers to anenvironment that brings together the tools needed to develop software.Typically this means an editor, build system and debugger. This enablesthe development of software without having to continually switch betweentools.

The editor in Code Composer Studio includes a wide breadth of featuresto make development easier. Standard features such as customizablesyntax highlighting and code completion are present, as well as moreunique features such as local history. The local history keeps track ofsource code changes and enables the comparison or replacement of thecurrent source with those in the history.

The project management system allows for the building of projects witheither the TI compiler or GCC. It also integrates with standard sourcecontrol software such as Git.

The integrated debugger allows for the debugging of applications runningon TI embedded devices and is discussed in more detail in the debuggingchapter.

2.4.2. Compiler¶

C/C++ Compilers are provided for each instruction set. In most casesthis is a TI proprietary compiler. For Cortex A devices GCC is providedbut in general it is recommended to use the compiler that is bundledwith the SDK for the device. For MSP430 and Cortex M based MCUs a TIproprietary compiler and GCC are provided. GCC is the open source GNUcompiler. Additional compilers are available from the App Center.

2.4.3. Resource Explorer¶

Resource Explorer helps you find all the latest examples, libraries,demo applications, datasheets, and more for your chosen platform.

Filtering by device, or by TI LaunchPad™ Kit, the interface enables youto filter the content to only what is relevant to your chosen platform.Resource Explorer will show you not only the resources that you haveinstalled on your local computer but also those that are located onlineand available for download. When you select an example from a softwarepackage that you have not yet installed Resource Explorer will allow youto install that package, and any necessary dependencies, and then allowyou to import the example into your workspace.

Resource Explorer can be accessed from menu View → Resource Explorer.

More information on Resource Explorer is availablehere.

2.4.4. App Center¶

Similar in concept to Resource Explorer, App Center is used to obtainadditional items required for development. While Resource Explorer isused to obtain software and documentation, App Center is primarily usedto obtain extensions or add-ons to the Code Composer Studio environmentsuch as compilers.

Resource Explorer can be accessed from menu View → CCS App Center.

More information on App Center is availablehere.

TI offers a wide selection of debug probes that enable softwaredevelopment on TI embedded processors. TI’s debug probes are designed tomeet different needs in terms of functionality and budget. Each probe iscompatible with Code Composer Studio.

Developing software typically requires downloading the resulting programto the embedded processor it was written for. A debug probe provides adebug communication pathway between a host computer and the embeddedprocessor. This allows for downloading of the program as well ascontrolling the processor to enable debugging.

More information on the debug probes available for TI embeddedprocessors is availablehere.

Note that it is possible to add support for additional debug probes toan existing Code Composer Studio installation by running the installeragain and pointing it at the current installation.

The E2E support community is the primary method for obtaining supportfor developing on TI processors. Thisarticleprovides more information on support resources.

8.1.1. Can I install multiple versions of CCS on my computer?¶

Yes. Multiple versions of CCS can be installed on the same machine aslong as they are installed in different directories.

8.1.2. What is the difference between the web installer and the offline installer?¶

The web installer is a lightweight installation program. The initialdownload is very small and enables the selection of features and devicesupport to install. Once the selections are made the installer will thendownload the appropriate packages to complete the desired selection.

The offline installer, or full installer, is a larger installationprogram. The download contains all of the available installationoptions. This installer does not require internet connectivity to run.This installer is recommended if your firewall or anti-virus software isblocking the web installer.

8.1.3. My username has Unicode characters and CCS fails to install. How do I resolve this?¶

Due to a limitation in the Eclipse Application Framework used by CCS,the username cannot contain any Unicode characters. In order to installthe product, please create a temporary admin user without any Unicodecharacters and install CCS for all users.

8.1.4. Why does the Linux installer just exit without doing anything?¶

The installer requires some packages to be installed in order to run.You are likely missing one or more of these packages. Please refer toLinux Host Support for moreinformation on installing on Linux.

8.1.5. Why does the Windows installer just exit without doing anything?¶

There is some software that sets up the TCL_LIBRARY environment variablewhich is interfering with the CCS installer. Please unset this variabletemporarily, before trying the install.

8.1.6. After installing on Linux, why does CCS refuse to open?¶

When double-clicking the desktop icon nothing happens, and if launchingfrom a command line, the following error is shown:

This may happen when updating or installing a newer version of the samestream of CCS (8.0.0 to 8.1.0, for example). The cause is that, if CCSwas previously launched as root, the temporary directory in the userarea may have become tainted and its ownership was set to root. In otherwords, the temporary CCS directory would look similar to:

To fix this, use chown to change the ownership of all the directoriesand the .lock file back to the user

8.1.7. After installing CCS, I found out some features (such as certain processor families or debug probes) are missing. Is there a way to add these features?¶

Yes. Simply re-run the installer executable (either online or offline).Follow the installer screens and select the same directory as theoriginal install. Keep following the installer screens and select themissing components.

Certain features (such as code generation tools updates) can beinstalled from inside CCS (using menu Help → Install New Software),however this method cannot be used to add support for additionalprocesssor families and debug probes. You would need to re-run theinstaller to add this support. Check the CCSUpdatespage for more details.

8.1.8. When installing CCS it says “An error occured: can’t read”update“: no such variable”. How do I resolve this?¶

Make sure you are installing CCS to a clean directory where a previousinstallation does not exist.

8.1.9. When trying to install compiler tools, CCS says it is already installed but it is actually not. How do I fix it?¶

This could happen if a prior attempt at installing the compiler toolsdid not complete properly. In such cases, the menu Help → InstallationDetails → Installed Software will list that version of compiler toolsas installed, however the files will really not be in the file systemand the compiler version will not be in the list of Discovered Toolsunder menu Window → Preferences → Code Composer Studio → Build →Compilers.

To resolve the issue, look for the compiler installer executable in thefolder <ccs_install_dir>/ccsv[x]/eclipse/downloads. It will be namedsomething like ti_cgt_tms470_5.0.11_windows_installer.exe, for example.Run the installer manually as administrator and tell it to install intothe <ccs_install_dir>/ccsv[x]/tools/compiler/arm_<version> directory.

8.1.10. How can I perform a silent or unattended installation of CCS?¶

CCS can be installed from command line interface with several options, including unattended installtion. Please refer to the CCS Installer Usage article for more details.

8.2.1. What is the licensing policy for CCS?¶

There is no license fee associated with CCS. Users are free to downloadand install Code Composer Studio without having to purchase a license.

8.3.1. How do I get updates to CCS?¶

By default CCS automatically checks for updates each time it starts.This update check will find updates to features that are alreadyinstalled. For example, it will find updates to the CCS IDE, compilerbug fix release, and device support. It will not find new featuresincluding new feature revisions of the compiler. See the CCSUpdates page for more details.

8.3.2. How do I search for new features for CCS?¶

The CCS App Center which is accessible from the View menu is useful forfinding new features. The App Center will highlight a selection of newfeatures that are relevant to the device families that you haveinstalled.

There are a few other ways to find and install new compiler tools. Referto the procedures described in the CompilerUpdates article.

8.3.3. How do I get TI-RTOS Updates?¶

The main way to get TI-RTOS is via ResourceExplorer which will automaticallyshow you the latest version of TI-RTOS or the SDK that it is includedin.

8.3.4. When installing CCS updates I get a dialog box that warns me that the feature is unsigned. Is this a problem?¶

Most updates released by TI are signed, however not all of them are.Similarly an update or feature from a partner may not be digitallysigned. When this happens CCS produces a warning noting that the featurehas not been signed. In general these are safe to ignore but it is bestto always make sure you know where the update is coming from beforeinstalling it.

8.4.1. How do I override the TEMP and TMP environment variables that are used to determine where temporary files are placed during CCS build process?¶

During the CCS build process, gmake creates temporary batch files in thedirectory that corresponds to the user’s TEMP and TMP System EnvironmentVariables. The compiler also uses this directory for temporary filesduring compilation. CCS has the ability to let the user override theseenvironment variables within the scope of CCS, so you don’t have tomodify your global System variables.

In CCS, open the menu Window → Preferences → C/C++ → Build →Environment, and use the Add button to add the two variables:

Set the appropriate button to either “Append” or “Replace” variables tonative environment. On Windows, make sure to use backslashes (notforward slashes) in the paths. Also make sure the directory specifiedfor the variables exists before running the build.

8.4.2. Is it possible to convert a non-RTSC CCS project to a RTSC project, and vice-versa?¶

To convert a non-RTSC project to a RTSC project, simply add a RTSCconfiguration file (.cfg) to the project. CCS will ask if you want toenable RTSC support for the project and if you click Yes, willconvert it to a RTSC project.

It is not possible to convert a RTSC project to a non-RTSC project. Inthis case, you would need to start over by creating a new project.

Ti Code Composer Download

8.4.3. During project build, a ccsLinker.opt file sometimes gets passed to the linker instead of the list of object files . What is this file and when is it used?¶

The ccsLinker.opt file is generated by CCS and passed to the linker ifthe list of linker options and input files on the linker command lineexceeds the maximum command line length of the host operating system. Aproject with a large number of object files (.obj) may pass the linkeroptions and input files to the linker via the ccsLinker.opt file ratherthan directly on the command line.

8.5.1. I get Data Verification errors when loading my program. What does it mean?¶

See this article on Data VerificationErrors

8.5.2. What is the difference between Run/Resume and Free Run?¶

Free Run disables breakpoints before executing code on the target.Essentially you are running free of the debugger. You will not seeupdates to any views or printfs when performing a Free Run.

8.5.3. How can I view non debuggable devices and routers in the Debug view?¶

The Debug view hides non-debuggable devices by default. If you wishto view these devices:

Right-click in the Debug view and select Show All Cores in thecontext menu. A node called Non Debuggable Devices will appear whichyou can then expand to see the devices.

You can also set this within a given debug configuration so every time adebug session is launched with that debug configuration (with or withoutassociated project), the settings will take effect. To do this, go toCCS menu Run → Debug Configurations, and enable Non DebuggableDevices and Routers for the desired debug configuration.

8.5.4. In multi-core devices, the CIO console prints out the CPU-core name after every output character. Is there a way to prevent this?¶

In CCS all the CIO output goes to a single console by default, so CCSinserts the CPU-core name in front so that you can tell which core it iscoming from. For assert() statements, the CPU-core name is addedwhenever a given CPU flushes its CIO buffer, making the output verydifficult to read.

There is an option to control this. Go to menu Run → DebugConfigurations, select your debug configuration and uncheck the optionUse the same console for the CIO of all CPUs.

8.5.5. My BeagleBone is Rev A5 and greater, but I still can’t connect to CCS . Why?¶

If you are getting this error when trying to connect to the board:

Download Code Composer Studio For Free

Or getting this when running the xds100serial utility:

Or the Windows control panel is showing two USB serial ports when youconnect the board to the PC, then you have a BeagleBone board with ablank (non-programmed) FTDI device.

The solution is to program the board with a known good configuration.One can be found at CircuitCo’s BeagleBonepage.

8.5.6. Can I debug two boards using two separate emulators at the same time?¶

Yes, this is possible. See this article for more details: Debuggingwith Multiple Debug Probes.

8.5.7. When debugging program in cache why do cache lines get invalidated?¶

For any kind of action that involves setting software breakpoints (thisalso includes single-stepping or running to an address) on C6x, thecorresponding cache line is invalidated. This is expected behavior sincesoftware breakpoints require the breakpoint opcode being written to theprogram memory at that address.

8.5.8. After connecting to target and loading the program why are the menus/icons for target execution (resume, suspend, step, etc) not available (greyed out)?¶

Make sure that the Debug view was not inadvertently closed duringthe debug session. If it was closed, you can bring it back by going tothe CCS menu View → Debug.

8.5.9. How do I resolve this error when launching a debug session “Could not fetch next record for SQL statement” and running fsclean does not help.¶

Try deleting the target cache files as described in the Troubleshootingchapter

8.5.10. How do I resolve error “Cannot read System Setup data from XML file <file path/name>.ccxml. XML configuration file has no <configurations> root node”?¶

Try creating and using a new target configuration file.

8.5.11. Is it possible for the Graphs view and properties to carry over from one CCS session to another, so when CCS is restarted the graphs come up again?¶

CCS saves the arrangement and contents of graph views when a debugsession is terminated and restarted, but not when CCS itself is shutdown and restarted. The solution to help streamline the input ofgraphing properties is the Export and Import buttons at thebottom of the graph properties. You could export the graph properties toa file and then import it back when you restart CCS.

8.6.1. Are simulators no longer included with CCS?¶

Starting with CCSv6, simulators are no longer included. We are movingaway from providing simulators and instead focusing on providing lowcost development boards.

Ti Code Composer Studio Download

8.6.2. Are C54x devices supported in CCS?¶

Download Code Composer Studio

The last release to support C54x is CCSv5.5.

8.6.3. Can I use DSP/BIOS with current releases of CCS?¶

Yes you can use DSP/BIOS with current releases of CCS and buildprojects. However, the Real-time analysis features are not supportedwith DSP/BIOS.

8.6.4. Which operating systems are supported by CCS?¶

Please see the article on SystemRequirements.

8.6.5. Is the XDS510LC emulator from Spectrum Digital supported with F2837xS/D and F2807x devices?¶

Download Code Composer Studio For Windows 10

These devices have an Icepick router which is NOT supported by theXDS510LC. For these devices, please use one of the supported emulatorsas mentioned in this forumpost.

8.6.6. How do I modify the maximum Java heap size for Eclipse?¶

If you see an “out of memory” error in CCS, try changing the Eclipse heap setting. To do this, open ccstudio.ini in the /ccsv[x]/eclipse folder (/ccs/eclipse/Eclipse.app/Contents/Eclipse for MacOS) and adjust the “-Xmx” argument. Note that on Windows, CCS versions upto CCSv9 are 32-bit applications, hence there is a cap on how much this value can be increased for it to have effect. Also, having too high a value may cause other IDEstability problems depending on how much content is open in theworkspace and what features are being used. If you have 4+ GB of systemRAM, the “sweet spot” seems to be between 512m to 768m, and it worksbest for most users.

More information on Heap and Java Virtual Machine (JVM) memory settings can be found in the Troubleshooting section.
