SourcePoint™ for ARM® ArchitecturesA good debug solution offersthe programmer or developerlayers of debugging options -from the simple breakdown ofcode into ever smaller itera-tions to the ability to captureand analyze huge amounts ofexecution history in a singlerun. To meet developers’needs, American Arium offersseveral solutions, all of whichemploy the company’s flag-ship SourcePoint debugger.

Managing Run ControlThe key to a successful run control debug strategy liesin the ability to set accurate breakpoints and stepthrough code. SourcePoint offers processor and softbreaks via simple GUIs. Breaks can also be set fromthe Code window or a command line.

SourcePoint uses the usual stepping commands alongwith go and halt to step through source or assembly-level code. SourcePoint’s C-like command languageincludes not only industrystandard run control com-mands, but lets the developer execute loops, use dataand array variables, access file I/O, and more. Unlikesome command languages, SourcePoint is intuitive;developers do not need to know a twoletter code foreach command.

Intuitive windows can be opened to view the state ofthe processor and make modifications to values,including Symbols windows, Registers windows,Memory windows, and user-defined Watch windows.In multi-core environments, developers can maskprocessors together or individually and start, step,and stop those not masked.

Arium’s debug solutions aredesigned with time in mind.Whether downloading files orimages, stepping throughcode, or coming back afterhitting stop, the event exe-cutes with incredible speed.

Capturing, Filtering ANalyzing Execution HistoryFor developers who want more than run control,SourcePoint offers some of the best trace functionalityon the market today. The debugger handles trace via theEmbedded Trace Macrocell (ETM) in ARM processorsand produces solid execution history from XScaleprocessors. Several features make SourcePoint a true“solutions” debugger, including integrated trace, tracebuffer depth, easy multi-level triggering, and perform-ance analysis.

Integration. SourcePoint trace is integrated into the soft-ware package; it is not an “add on.” Advantages? There’sthe obvious - developers do not have to deal with (or payfor) a separate trace port analyzer. There is no new soft-ware to load. Users do not have the integration problemsthat plague add-on solutions. Apart from the obvious,the greatest advantage is being able to open a Code win-dow and scroll through the collected trace, examiningthe actual code and how the compiler compiled it, withcorrelated code and trace.

Deep/fast trace. With Arium’s GT-1000D emulator,SourcePoint delivers trace depth up to 1 GByte with acapture rate up to 640 MHz, depending on the applica-tion. For those who can get along with a smallerbuffer, there’s the HS-1000, which offers 256 MBytesof trace at a blazing 680 MHz.

Multi-level triggering. When used with the GT-1000Dor HS-1000 and a target with ETMv1 or ETMv3,SourcePoint offers superb complex sequencing via aseries of user-friendly GUIs. Based on breakpoints andother user-defined events, trigger parameters can bequalified or refined. For example, an event may occurthousands of times in a program. A developer can setup a breakpoint to trigger only after the first thousandtimes it occurs and only if it occurs after a particularaddress. Unlike other debuggers, SourcePoint doesnot require “rocket science” to set up the triggeringsequence.

Performance analysis. SourcePointincludes performance analysis for usewith ARM cores with ETM. While mostdevelopment tools rely on a compiler tohandle performance analysis, SourcePointuses the ARM ETM to mine data fromcode. The ETM has up to 16 address com-parators that can be programmed withfunction entry and exit points.

Trace qualification is used to record onlythose addresses in the trace buffer. Thisgives the developer approximately140,000 real-time entry and exit points in

SourcePoint™ for ARM® Architecturesa 1 MB trace buffer (each address gen-erating a 5-byte broadcast addressconsuming 7 cycles), resulting in a sin-gle trace capture that can contain thou-sands of instances of each addressrange. This solution requires nochanges to the user's program, andmeasured performance data match thereal execution time of the programbeing run.

Arium also offers code profiling for tar-gets with processors without ETM.

SourcePoint on a Linux PlatformSourcePoint delivers industry-leading functionality fordevelopers working on Linux-based embedded systems,including:• Full symbolic, source-level debugging of Linux

kernel code• Source-level debugging of Linux embedded

applications• Launch of or attachment to processes with seamless transitions to and from the kernel and each process• Code debug on initial target bringup immediately

from board reset• Dynamically loaded module debug (insmod)• Threaded application debug support• Linux shared libraries debug• Specialized breakpoints to stop the execution of a

process without stopping the processor or causingit to enter debug mode

• Flash programming for kernel and file-system download

SourcePoint™ for ARM® Architectures• Linux console hosting devices from within

SourcePoint, eliminating the need for a serial port orvideo device on the target and simplifying the debugging of "headless systems"

• Intuitive, Windows-like debug environment

SourcePoint allows concurrent debugging of Linuxkernel code and Linux application processes. WithinSourcePoint, two views provide the interfaces toLinux-aware debugging features. The OperatingSystem window lists Linux processes and serves asthe primary interface for task debugging. The TargetConsole window emulates multiple terminals thatserve as the Linux system console and as the standardinput and output device for processes launched fordebugging.

Shortcuts within shortcutsSourcePoint incorporates hundreds of options, com-mands, and functionalities designed to spur the debugprocess forward. Windows are designed to be intu-itive. They can be docked, floated, or minimized. Com-mands are available from multiple locations - menubars, icon bars, context menus, a command line.Symbols and their values are easy to find and change.

Items are grouped logically in intuitive windows anddialog boxes. For example, target configurationoptions exist under a single view. From the dialog, thememory map of the target can be defined, the type andaddress range of flash memory devices declared, and

SourcePoint™ for ARM® Architecturestarget flash operations performed. Target configurationscan be loaded from a developer’s target database file andsaved to SourcePoint and/or the target database file.

SourcePoint offers a number of userdefined options.These include windows that allow definition of memo-rymapped I/O devices and related registers and areas ofmemory in one view. Developers can keep track of mul-tiple devices without having to keep multiple views ontheir screen.

Outstanding SupportAmerican Arium offers exceptional service and supportfor all of its debug solutions.
