While memory is not accessible all windows will report Can not access RTOS state. This is normal until the debug session with download is started. If the message is still shown after download the object symbols probably cannot be evaluated.
Open the Symbol Browser via View| Debug | Symbol Browser (ALT + F12) and verify their presence to confirm that symbols are available. Symbols differ in different versions of rcX RTOS:
Symbol availability depends on a code, compile tool and its settings, download file debug format, loader settings, etc. To adjust Symbol Files options:
1. Open Debug | Configure Session | Applications | Symbol Files.
2. Select the Symbol File and press Edit.
4. Press Advanced to open the dialog for setting advanced options.
