Page 3: Introduction
(the document you are reading at the moment) is CPU specific, while all other parts of the online help are generic for all CPUs supported by Lauterbach. So if there are questions related to the CPU, the Processor Architecture Manual should be your first choice. - Page 4 Switch the target power ON. Configure your debugger e.g. via a start-up script. Power down: Switch off the target power. Disconnect the debug cable from the target. Close the TRACE32 software. Power OFF the TRACE32 hardware. ©1989-2019 Lauterbach GmbH MMDSP Debugger...

Page 9: Cpu Specific Implementations
Software breakpoints • On-chip breakpoints For MMDSP it is only possible to set breakpoints when the clock is stopped. This applies to both software and on-chip breakpoints. Software Breakpoints In order to stop the program execution at a selected instruction, the code at the break location is patched by a software break instruction. -
Page 10: On-Chip Breakpoints
This implementation is called on-chip, because the debugger uses resources provided by the processor to set a breakpoint. The MMDSP core is equipped with 2 watchpoint/breakpoint units. The following list gives an overview of the usage of the on-chip breakpoints by TRACE32-ICD: •... -
Page 11: Downloading Program Code To The Video Core
Therefore the /verify option for the data.load command may produce false error message when used for download code to the video core. Changing the FLAG Register Changing the FLAG register through the debugger is not supported. ©1989-2019 Lauterbach GmbH MMDSP Debugger... -
Page 12: Memory Classes
The DBG memory class gives access to memory resources like host register, indirect host registers, and dictionary ram (Video core only). The mapping of these resources to addresses is arbitrary and does not relate to any MMDSP or system address mappings. The mapping is only valid in the context of the DBG memory class. - Page 13 Note that for MMDSP it is not possible to access memory through the debugger while the core is executing code. For not CPU-specific keywords, see non-declarable input variables “ICE/FIRE Analyzer Trigger Unit Programming Guide” (analyzer_prog.pdf). ©1989-2019 Lauterbach GmbH MMDSP Debugger...

Page 14: System Config
To bundle several cores in one processor as required by the system this command has to be used to define core and processor coordinates within the system topology. Further information can be found in SYStem.CONFIG.CORE. ©1989-2019 Lauterbach GmbH MMDSP Debugger... - Page 15 (default: OFF) If more than one debugger share the same debug port, all except one must have this option active. JTAG: Only one debugger - the “master” - is allowed to control the signals nTRST and nSRST (nRESET). ©1989-2019 Lauterbach GmbH MMDSP Debugger...

- Page 20 StopAndGo, conditional breakpoints etc. For MMDSP the option NonStop reduces the functionality to tracing the program flow as no memory access can be performed by the debugger while the clock is running.
-
Page 21: System Lock
If the system is locked, no access to the debug port will be performed by the debugger. While locked, the debug connector of the debugger is tristated. The main intention of the lock command is to give debug access to another tool. ©1989-2019 Lauterbach GmbH MMDSP Debugger... -
Page 22: System Mode
In general the SYStem.MemAccess command controls how the debugger accesses system memories while the clock is running. Due to the design of MMDSP there is no way for the debugger to access memory resources without stopping the clock. Therefore the only possible selection for this option is denied. - Page 23 DSP core is in. For changing the DCU mode in the target, the FLAGS register needs to be modified in the target.

- Page 24 SYStem.Option EnReset [ON | OFF] Default: OFF. The command controls whether the debugger will (ever) pull the reset line. As the MMDSP is normally used as "slave" in multi-core systems, the default setting for the option is OFF. Consequently the reset line will never be activated on default.

- Page 28 StopAndGo is that for "stopandgo" the debugger will indicate real-time violations (red "s" in the bottom status line). Also, snooping is much faster than StopAndGo and thus done more frequently which results in a more detailed statistical analysis. ©1989-2019 Lauterbach GmbH MMDSP Debugger...

Page 31: Jtag Connection
We strongly recommend to use a connector on your target with housing and having a center polarization (e.g. AMP: 2-827745-0). A connection the other way around indeed causes damage to the output driver of the debugger. ©1989-2019 Lauterbach GmbH MMDSP Debugger... - Page 32 JTAG connector is tristated by the debugger and it is pulled low otherwise. This signal is normally not required, but can be used to detect the tristate state if more than one debug tools are connected to the same JTAG port. ©1989-2019 Lauterbach GmbH MMDSP Debugger...
