To make MATLAB Link for Code Composer Studio 1.2 (R13.0.1+) fully compatible with Code Composer Studio 2.2, you need to download a patch.
Following are the steps for downloading the patch:
1. Download Link1p2PatchForCCS2p2.exe from the bottom of the page and copy it into the $MATLABROOT\toolbox\ccslink directory
(where $MATLABROOT is the root MATLAB directory)
2. Double-click on the executable Link1p2PatchForCCS2p2.exe' and click on 'Unzip'.
3. A window displaying "6 file(s) unzipped succesfully" will appear. Click OK and close the WinZip window.
4. Restart MATLAB

Following are some of the issues you may come across when using MATLAB Link for Code Composer Studio 1.2 (R13.0.1+) with Code Composer Studio 2.2 and the corresponding solutions for these issues.
--------------------------------------------------------------------------------
1. Time-out issue with demos on OMAP Simulator
Problem:
- Setup OMAP CCS 2.2 for OMAP3.1 Platform Simulator and run ccstutorial/ccsfirdemo/multiproctutorial
- At some point the demo seems to stop and a time out error is thrown in MATLAB.
Solution:
This is due to a bug in the OMAP3.1 Platform Simulator on CCS 2.2 - if you open and load any ARM or C55x program, it takes a long time to run to any point in the program.
--------------------------------------------------------------------------------
2. Demo issues on the C5416 DSK using XDS-510
Problem 1:
When running rtdxtutorial, the demo terminates and you get the error:
Enable: Enable failed on channel: ichan
Problem 2:
When running rtdxlmsdemo, at the point when the following text is displayed in MATLAB
Reading coefficient updates and filtered results from target - frame 1...
the process takes a long time and eventually errors out: ERROR: ReadMsg: Timeout waiting for CCS to confirm completion: waiting for 1 message 50 seconds might not be enough time for reading the data messages. Hit the 'view script' button and increase the value of the 'TimeOut' variable at the beginning of the script.
Solution:
- Open the CCS IDE
- At the left pane, click (+) on GEL Files and remove the existing GEL file(s) loaded.
- Left-click GEL Files again and choose Load GEL… Go to TIROOT\cc\gel and choose c5416_dsk.gel. (where TIROOT is the root folder for TI)
- Re-run the demo.
--------------------------------------------------------------------------------
3. ccsfirdemo times out on the C2812 DSK using XDS-510
Problem:
When running ccsfirdemo, it times out during the Run Target stage.
Solution:
Download the patch Link1p2PatchForCCS2p2.exe.
--------------------------------------------------------------------------------
4. RTDXTUTORIAL/RTDXLMSDEMO on OMAP Simulator
Problem:
Setup OMAP CCS 2.2 for OMAP3.1 Platform Simulator
Problem description:
- Run rtdxtutorial (or rtdxlmsdemo) and choose the C5500 processor when prompted to select a target.
- During 'load', a dialog box pops up in the CCS IDE:
RTDX target application does not match emulation protocol!
Loaded program was created with an rtdx library which does not match the target device.
- If you hit OK and continue with the demo, eventually the demo errors out and exits. Error thrown in MATLAB is:
ERROR: "CCSDSP:The server threw an exception."
This error is related to demo issue no.1 (Time-out issue with demos in OMAP
simulator). You can still run RTDXLMSDEMO or RTDXTUTORIAL on a C55x
simulator by configuring a single C55x simulator in your CCS Set-up instead
of using the OMAP simulator and then running the demo.
--------------------------------------------------------------------------------
5. CCSTUTORIAL/CCSFIRDEMO on ARM 7 Big Endian Simulator
Problem:
During 'load', a dialog box pops up in the CCS IDE:
Data verification failed at address 0x20.
Please verify target memory and memory map."
Solution:
- Before running ccstutorial or ccsfirdemo, open CCS IDE and do the following:
- Go to the Option menu
- Select Memory Map...
- Enable Memory Mapping
- Enter a Starting Address of 0x20
- Enter a Length of 0x7FFE0
- Enter Attributes of RAM
- Click the Add button
- Click Done to leave the dialog
Also, when running the ccstutorial, CCS IDE throws the message: "Can't Run Target CPU: Error number -2164 Error address 0" in the Messages window. This does not affect the demo.
--------------------------------------------------------------------------------
6. RTDXLMSDEMO on C6211 Big Endian Simulator
Problem:
During load, a dialog box pops up in the CCS IDE:
File C:\MATLAB6p5\toolbox\ccslink\ccsdemos\rtdxlms\c6x\rtdxdemo_sim6xe.out
Does not match the target type, not loaded.
Solution:
- You have to rebuild the project rtddemo_sim6xe.pjt in $MATLAB\toolbox\ccslink\ccsdemos\rtdxlms\c6x:
- Open the project in the CCS IDE. Go to Project->Build Options. Under the Compiler tab, select C621x (-mv6210) under Target Version. Click OK.
- Build the project and re-run the demo.
Note: Since other processors use the same demo project, make sure you to return the Build Options to its original settings and rebuild the project.
