Emulator Troubleshooting Guide
Contributed Kathleen Smith March 2004
Introduction
Tools Technical Support (dsptools.support@analog.com) handles initial email requests regarding problems with in-circuit emulators (ICE). Most problems resolved e-mail. Authorization return units reserved until other options have been exhausted. resolve problems e-mail, support team needs much information possible identify problem provide solution. following troubleshooting guide suggests quickly easily resolve most installation, connection, software problems. highlights information required support team authorize return emulator repair.

Installation
installation CD-ROMs, which accompany emulators, include full documentation .pdf format. documentation also available free downloads from Analog Devices site. URLs listed below. Perform hardware installation configuration using these documents. When reporting faults, confirm that followed these procedures indicate exact step number that produced error. sure provide full details error message received.
Other Equipment
support team needs know which operating system, evaluation system board, version VisualDSP++® using. This information used confirm compatibility duplicate problem lab. Indicate whether have third-party multiprocessor board, clustered multiple boards, externally configured memory. these factors affect configuration your equipment.

Source Code
Ensure that source code correct that emulator problems caused programming issues. will useful support team confirm these troubleshooting steps. doubt, your project send Tools Technical Support (dsptools.support@analog.com) build lab. Does your project build without errors warnings? This fact help eliminate code IDE/IDDE source problems. Does your code simulation? answer this question indicates that your executable file good.

Apex-ICE interface therefore compatible with Windows EZ-KIT Litelicensed versions (the serial number begins with KIT-) VisualDSP++ support emulation simulation. ADSP-218x EZ-ICE software compatible with 32-bit VisualDSP++ software.
16-bit tools come with utilities test communication between PC's serial port your EZ-KIT Lite between PC's serial port your emulator. However, Microsoft® utility available. Appendix which brief guideline using HyperTerminal test confirm that communications functioning properly. Perform this test provide support team with results when report problem.

These explained detailed VisualDSP++ online Help emulator guides (the URLs listed installation section above). guides explain exactly which step, causes error. List received error messages confirm whether these utilities have been with errors.
Basic Troubleshooting Eliminate Other Possibilities
Other emulators available, other emulators, same type other types ensure that problem related particular unit incompatibility emulator type.
Debug Session List
Occasionally, corrupted session causes emulator/debugger stop responding. correct this, follow guidelines below. Confirm support team that have tried this, provide results. From Start menu, press hold CTRL open debugger. When Session List dialog appears, delete sessions currently defined. Immediately close dialog without entering debugger. Enter system registry \start\run\regedit command. Delete keys under following folder:
Devices\VisualDSP\Debugger (IDDE) \Debug Session List
Emulator problems often difficult confirm. process elimination often good proceed. Check hardware following list errors. hardware problem with emulator. sure inform support team checks made results. Cables Ensure proper insertion. Replace them with other known working cables, available. Ports another port another known working emulator, available, same port. Ensure that adequate resources working emulator another available. Code Primes demo program. SHARC®- ADSP-219x-based custom board Ensure that conforms JTAG regulations described EE-68 [1]. Refer following URL:

Close registry then reboot. Open debugger again re-define required sessions.
Returns Policy

Warranty Details Proof Purchase
Appendix HyperTerminal Test
Background Information
Emulators that less than year within warranty. Repairs within that period free charge. must supply proof purchase returns that within warranty. Returns that outside this one-year period must accompanied payment order $300 (US) full emulator, $160 (US) only repair.
HyperTerminal test utility used test ADSP-218x EZ-ICE over serial port interface. ADSP-218x EZ-ICE requires serial port interface with will work with JTAG ICETest utility. HyperTerminal does variety things. tests interface between "TARGET" target customer board with it), EZ-ICE. tests communications from EZICE over ribbon cable target board. HyperTerminal performs other internal tests such flash tests tests. result being able actually perform these tests (see menu screen from HyperTerminal), fundamental test communication between EZ-ICE occurs. Think block diagram where block, EZ-ICE another, target third block.

Using emulator other than intended purpose invalidates warranty.
Company Details
When provide Analog Devices with warranty details, confirm your company's contact information customer database kept date.
Emulator Serial Number
Analog Devices also needs provide emulator serial number. Apex-ICE serial number located bottom shielded box. Summit-ICE, HPPCI-ICE, Mountain-ICE serial numbers located emulator card.

Running Test
HyperTerminal Windows utility, which requires that your target powered connected your ICE. Windows 9x/ME, this utility found under Windows 2000, found under
Look line red). Immediately after press Reset button EZ-ICE, press Enter your keyboard. This opens another menu that looks like this:

invoke VisualDSP++ HyperTerminal same time. other words, leave HyperTerminal open minimized) background bring VisualDSP++. port already been allocated HyperTerminal software cannot shared with VisualDSP++. Consequently, VisualDSP++ cannot communicate with target same time using port HyperTerminal. HyperTerminal test: With ICETest utility 1.00.9 installed, must know what port being used when running HyperTerminal test. Bring HyperTerminal utility click hyperterminal.exe. Fill name test. Select port connected your ICE. Select following port properties/ port settings: Bits second= 9600 Data bits= Parity none Stop bits Flow control hardware Click With powered connected your target, press Reset button once. following splash screen:

When this menu appears, tests menu items pressing that letter then pressing Enter. example, when test, screen might look like:

Line warns that flash will erased will need reprogrammed. Lines 490510 flash passed various different tests. When install emulator software this test first time, asks press Reset check firmware version. then writes this version Registry does need check again. HyperTerminal select flash test, test destructive flash erases start VisualDSP++, .DLL invoked. Unfortunately, .DLL knowing that flash destroyed, fails. restore flash emulator, perform following procedure will able emulator with debugger. Close debugger HyperTerminal. START type regedit. H_KEY_Current User Software Analog Devices VisualDSP delete 218x folder. Close Registry. Restart VisualDSP++ debugger select proper session that represents your target. This assumes corrected problem discovered during HyperTerminal interface test. deleting registry key, .DLL forced recheck version. When does, will incorrect, .DLL will reprogram flash.
Lines through show result this test. this example case, test passed without errors. typing then Enter, flash test selected. Typically, flash tests destructive contents flash; this exception. into this test, type 'f', Enter, then Enter must type within second Enter test will performed. fast enough, looks like this:
