CCS debugger restart doesn't go back to main()

Hi Eli,

Depending on the device and application, sometimes a restart will not work as intended. If you do a system reset then try a restart, does that help?

Thanks

Hi Ki,

I'm debugging a program step by step <F6> then I'd like to use the restart icon on the CCS menu and start from the main()

instead the program counter goes to 0.

Is there a way to configure it to go to main() ?

Thanks,

Eli

a CCS Restart will set the program counter to the entry point of the application (usually _c_int00 for TI compiled executable). There is a debugger option to autorun to main on CCS restart. This is ON by default. Hence restart should set the application halted at main. If you are not able to get back to main, then there is likely an issue with the target state when the restart occurs, preventing the application from reaching main again. Try disabling the autorun on program restart option and see if you get to the entry point. Then see if you can run to main. If it fails to reach main, then it is a application and target issue, not a debugger issue.

Hi Ki,

When I unchecked the "Connect to target on debugger startup

and  checked the "Continue debug launch if target conn...."  -   the debugger stopped working !

So I restored the default.

Now the debugger works (<F6> , <F5> and BP) but still the restart doesn't go to main().

Maybe there's  some more configurations has to be done for that ? Maybe a script or GEL ?

I'm using the simple "Hello World" SDK_243x example so there's nothing special in the program.

Please advice.

Thanks,

Eli

The option you want to disable is  "On a program load a restart" option. This will disable autorun to main.

I tried the same example with the option disabled. After running successfully, a restart will set the program counter to the entry point. Then when i run from there, it never reaches main but instead gets stuck below:

A system reset and reconnect/reload will resolve the issue. But why do I have to do this? I can't answer that as this is an issue specific to the application and target. It is not a debugger issue.

I will bring this thread to the attention of the device experts.

Thanks

Many users will appreciate if restart icon works.

To clarify - the restart button works fine. It is doing what is expected - setting the program counter to the address of the entry point of the loaded application. The issue is that from the entry point, the application is unable to run to main. This is NOT an issue with the restart feature or the debugger. It is a target and application issue.

Thanks
