TMS320F28069: TMS320F28069

Hi George,

Can you be a little more specific on your debug requirements, what you tried in CCS, and how it was insufficient?  

Are you interested in a snapshot of multiple variables at one time instant? The change in one-or more variables over time?  What duration time-slices are relevant to your debug? 

In general, if you are using JTAG, you will be limited to the JTAG interface speed (at best several Mbps).  Using JTAG, different emulators (e.g. XDS100 vs XDS510USB) will also support different JTAG clock rates. 

If JTAG data rates are sufficient, but CCS doesn't quite have what you want, you can try debug-server scripting: https://software-dl.ti.com/ccs/esd/documents/users_guide/sdto_dss_handbook.html

If you need to get more data out than JTAG could support, you'll need some custom code + use of a higher speed interface.  SPI or CAN would probably be the place to start.  You could also use a bank of GPIOs + some type of digital capture card.

Thanks Devin for your response! We generate the code using MATLAB. We don't use CCS. We are looking for the most appropriate method to debug the internal variables of the motor in real time to analyze the waveforms and everything else in details/That being said, what is your proposed method ? 

If you are not using CCS, then its data logging is irrelevant. 

In Simulink, you can use a SCI peripheral to throw out the data of your concern and capture them in a hyper-terminal. I recommend you to review examples in Matlab to help with that.

Hi,

The 2 model approach between target and host will likely help. Here is the page:

Look for: Fast Serial Data Monitoring

HTH,

Thanks Ramesh! The SCI peripheral in MATLAB is so slow! We are looking for a real time solution to capture the waveforms of internal motor control variables. Any suggestion?
