CCS/TMS320C6474: Real-time debugging on c6474

Part Number: TMS320C6474

Tool/software: Code Composer Studio

Hi,

I am trouble reading values and expression in real-time from CCS on c6474 using debugger. The program says "Error: Could not read <address>: Execution state prevented access". I have looked around the forum for similar issues, and found out that the problem is because the DSP is running in free running state. A fix for this is check "Halt the target before any debugger access'' in the project's debug properties.

But unfortunately, I cannot use active project based debug session. I need to use a non-project based debug session and read some variables. There is no option for halting the target when opening a debug session using .ccxml file. Is there a workaround for this..? I need to open a non-project debug session, load symbols and then read some variables all while not halting the system. TY.

Hello,

For a non-project based debug session, the option can be accessed via: "Tools -> Debugger Options -> Auto Run and Launch Options". Then in the view that is opened, check for the option under "Realtime Options"

Note the "Remember My Settings" button if you want to preserve the setting for subsequent debug session launches.

Thanks

Thank you Ki-Soo for the suggestion. Unfortunately, I am using CCS 4.2.1.00004. In this there is no Debugger Options under tools. I only see Pin, Port connects, Graphg, ROv, RTA, XDS tools, profile, trace control, trace analyzer. No debugger option under this. Is there any where else I can find this option...? Please advice. TY
