[FAQ] TMS320F28384D: [FAQ] ERAD: Unable to write to ERAD_GLOBAL_REGS[GLBL_OWNER] register and change module ownership (CCS v11.0 or older)

When running application code from Flash, ERAD_GLOBAL_REGS[GLBL_OWNER] does not change when written to from the CCS registers view or from application code, even with EALLOW enabled. Why does the register write fail?

    For Code Composer Studio versions 11.0 and older, the CCS debugger will automatically use the ERAD to set hardware breakpoints when executing code from Flash. Once a breakpoint is requested, the CCS debugger grabs ownership of the module, preventing the user from claiming ownership for other tasks. This issue was fixed in CCS v11.1. To resolve this issue, upgrade to a newer version of Code Composer Studio.
