To set a breakpoint in a __ramfunc declared function, the program execution must have reached the main function. The system startup code moves all __ramfunc declared functions from their stored location—normally flash memory—to their RAM location, which means the __ramfunc declared functions are not in their proper place and breakpoints cannot be set until you have executed up to the main function. Use the Restore software breakpoints option to solve this problem, see Breakpoints options, specifically the Restore software breakpoints option.

In addition, breakpoints in __ramfunc declared functions added from the editor have to be disabled prior to invoking C-SPY and prior to exiting a debug session.
