[dsdp-dd-dev] Invalid register names in Register View when tried to debug with a MIPS gdb and DSF

Hi All,


 I am trying to use DSF C/C++ Remote Application debug launch to debug a MIPS target using a cross compiled MIPS gdb (based on gdb 6.8) and a MIPS GDB Server which can communicate with MIPS target using an EJTAG probe. I am able to connect to the target successfully. But I am bit confused on why the register view lists lot of “Unknown” registers with value as “Error: Failed to execute MI command: -data-list-register-values x 0 Error message from debugger back end: bad register number”  before and after the normal MIPS registers. (see attached screen shot)


 When I tried to debug MIPS target with CDT Hardware Debugger launch configuration (which uses the CDI MI implementation) using the same gdb and GDB Server this behaviour was not there. I checked the output of -data-list-register-names MI command and I can see lot of empty strings(“”) in the register name list before and after MISP register names.


Is it some difference in the way DSF MI and CDT MI implementation interprets the output of -data-list-register-names is causing the issue?
