FET debugger

• Breakpoints
  

  There is a limited amount of hardware breakpoints available. When all available hardware breakpoints have been used, the FET debugger can use virtual breakpoints. This means that you will be able to set an unlimited number of breakpoints. The performance of the debugger will however be reduced as the debugger is forced to enter single-step mode as soon as the first virtual breakpoint has been set.

  If you are using the CLIB library, the debugger will set breakpoints on the exit label, and if terminal I/O is used, a breakpoint will also be set on the putchar/getchar label. It is possible to turn of the reservation of breakpoints on the exit and putchar/getchar labels. This can be done in the Flash Emulation Tool options dialog box.

  If you are using the DLIB library, the debugger will set a system breakpoint on the __DebugBreak label. You cannot dissable this behaviour.

• The Run to option
  

  The Run to option (available on the C-SPY setup options page) requires one breakpoint. If all hardware breakpoints have already been used, a virtual breakpoint will be set even if the use of virtual breakpoints has been turned off. This will force C-SPY into single-step mode and may, depending on the application, make the time to get to the specified location very long.

• In the list below the number of available hardware breakpoints and Enhanced Emulator features are listed for each group of devices.

Known Problems

• [EW430-1525] When using Elprotronic, it is not possible for msp430f2618/2619 devices to change sfr values in the register window.

• [EW430-1471] The GoTo Function (F12) does not work in some situations.

• [EW430-1431] Usage of multiple MSP-FET430UIF interfaces on one PC: There might be connection issues if multiple USB interfaces are connected to the same USB hub. Connect interfaces to different hubs or use only one interface.

• [EW430-1428] If you modify a breakpoint that is used by the sequencer, this breakpoint will be disabled. Therefore, to enable the breakpoint in the sequencer, open the Sequencer dialog box and add it again.

• [EW430-1427] It is not possible to reset the device using the Reset button on the toolbar while the application is running. You must first stop the execution.

• [EW430-1426] The following features can not be used when using the debug probe from Elprotronic: State storage, Sequencer, Advanced Cycle Counter, Samples Graph, Data Sample.

• [EW430-1425] It is not possible to simulate the CAPTIVATE_VECTOR interrupt.

• [EW430-1033, EW17284] The Watch window cannot show a structure if it has the same name as its type.

• [EW430-981, EW17957] Some interrupts with multiple sources, like ADC12, have interrupt vector registers like ADC12IV. These registers will not be set according to the triggered interrupt. As a result the interrupt simulations for those modules are not as useful. The simulation of TimerA1 and TimerB1 can handle multiple interrupt sources.

• [EW430-902, EW19351] C-SPY fails to start the debug session, after verify errors even if verify errors should not prevent that.

• [EW430-785, EW20579] The IDE might get unresponsive if you unplug the USB-FET cable during a debug session.

• [EW430-725, EW21096] The debugger can in some rare case crash with an "Unknown exception in drive(#E6)" when C-SPY macros are used for external communication.

• [EW430-718, EW21236] The graphical stack bar from Tools>Options does not work correctly with devices that have a mirrored RAM when the lower memory range is used in the linker file.

• [EW430-630, EW21856] The debugger can on some MSP430 devices cause a Vacant Memory Access exception. The reason for this is that the debugger is reading the register area from 0 -1000h in one block. But there are some holes in this area where no registers are memory-mapped and this causes a Vacant Memory Access exception.

• [EW430-446, EW23967] The Disassembly window does not display the content of the BSL memory area. As a workaround, add the area to the .ddf file, for example for MSP430F5529: Memory4 = BSL Memory 0x1000 0x17FF R

• [EW430-375, EW25335] The automatic selection of Debug Protocol does not work for MSP430F436.

• [EW430-348, EW25911] With the Elprotronic USB-FPA probes, the registers PxOUT are not displayed properly for MSP430F169.

• [EW430-336, EW26165] Single stepping in the Disassembly window can in some very rare occasions change the value of a variable.

Program Corrections

• [EW430-1526] It is not possible to store non-volatile data in the upper FRAM memory, because the memory is erased when reprogramming the device.

User guide corrections

The corrections below refer to the PDF versions of the user guide IAR Embedded Workbench C-SPY Debugging Guide for MSP430, UCS430-4.

Version 5.30.1 2011-06-30

New features

• Improved download speed
  When downloading an application to a device, the debugger can now compare the image with a cached copy of the image and only flash the sections that have changed. This will improve the download speed in many situations.

• Exclude memory segment from erase
  It is now possible to exclude a memory segment from erase, but only as a command line option which you can add on the Extra Option page. The option is called --erase_exclude, for example:
  

  --erase_exclude 0x2180-0x2220

  The segments that overlap with the specified area will not be erased.

Program corrections

• None.

Servicepack 5.20.4 2011-04-04

New features

• Support for LPMx.5 mode debugging
  It is now possible to debug applications that use the low power mode LPMx.5. To use this feature you must select the option Debug LPMx.5 on the FET debugger options page. The following limitations apply when the device is in the LPMx.5 mode:
  

  • You can not set or remove advanced, conditional or software breakpoints.

  • You can set HW breakpoints, but you can only remove HW breakpoints that was set after the device went down into LPMx.5 mode.

Program corrections

• EW22440: A problem in the JTAG stack of the msp430.dll could in some rare situations make the debugger lose control over the device.

version 4.21.6 - patch release

• EW21388: Writing to peripheral registers failed because the wrong memory address space had been specified in the .ddf file. This has been corrected.

• EW21377: The register SYSBERRIV was incorrectly included in the register description for MSP430F5438 and MSP430F5438A. It has been removed so that it no longer causes the debugger to stop the execution when the Register window is displayed.

• EW21349: When an interrupt occurs with a PC larger than 0xFFFF, the simulator no longer uses an address to the interrupt service routines that incorrectly also is above 0xFFFF. The interrupt service routines are always located below 0xFFFF.

• EW20804: The debugger no longer crashes when a conditional breakpoint is set and the debugger session is stopped while the application is running.

New features

• 64-bit device drivers for the TI FET USB tool are now included in the product installation. Drivers for the following systems are included:
  Windows XP 32/64, Windows Vista 32/64, Windows 7 32/64.

• Debugging multiple images
  C-SPY is now capable of debugging several independently built images during one debug session. Under Project options>Debugger>Images you specify the location of the images to be downloaded in addition to the current application. There is also a new debugger window called Images where you select for which application debug information shall be displayed.

• Auto refresh in the debugger memory window
  The debugger memory window can be refreshed during program execution, both manually and periodically.

• New cspybat features
  These new features have been added to cspybat:

• Symbols window
  A new Symbols window has been added to the C-SPY debugger. It displays the complete list of symbols used within the project. In contrast to the Source Browser, the list of symbols is not based on project source files but is retrieved from the debug information. This means that it also lists symbols from libraries for which you do not have the source for. It also lists assembler labels, which are not conveniently visible in any other window.

• Start the debugger without download
  You can now start the debugger with or without downloading code, using two new buttons on the toolbar or two new entries in the Project menu. There are also two new corresponding ways to restart the debugger during the debug session.

• A new argument variable $CONFIG_NAME$ has been added. It expands to the name of the current build configuration, for example Debug or Release.
• A new editor window context menu command Set Data Breakpoint for 'xxx' sets data breakpoints on variables with static storage duration.

v 4.11B - 2008-07-10

Program corrections

• EW20055: In some cases, evaluating variables of the type complex structures, for example via ToolTip, could lead to an abnormal termination of the IDE session. This has been corrected.

• EW19968: Some register names in the ddf files for MSP430F2132 and MSP430FG4270 have been corrected.
• EW19950: A problem with identifying the device when a MSP430F2617 was used has been corrected.
• EW19941: The "New Breakpoint..." dialog box would occasionally become too large, partially hiding window contents. This has been corrected.
• EW19901: A problem that caused the debugger to freeze at an invalid memory address (using MSP430X) has been corrected.
• EW19900: In some environments the IAR Embedded Workbench IDE could crash when the C-SPY debugger was started.

3.42A 2006-12-07

Program corrections

• EW18102: On a 430X device it was not possible to erase only main memory when downloading to flash. It was only possible to erase 'main and information memory'. This has been corrected.

New features

• Support for multiple TI USB FET modules
  It is now possible to attach multiple TI USB FET modules to a PC and select from the IDE which module to use in a debug session.

• Statics watch window
  The Statics window displays the value of variables with static storage duration, typically variables with file scope, but also static variables in functions and classes.

• Symbolic Memory window
  The Symbolic Memory window (similar to the Stack window) displays how variables with static storage duration are laid out in memory.

• Improved breakpoint display
  Breakpoints are now displayed in the editor window using different icons depending on the breakpoint type. Information about a specific breakpoint is displayed in a tool tip.

• Memory save/restore
  Transfers memory contents from/to a file. Restoring from file recognizes format automatically, saving to file requires specifying of format; available are intel-extended or different motorola format variants. This functionality is available from the Debug>Memory menu or through the Memory window context menu.

• µC/OS-II Kernel Awareness Plug-in in C-SPY
  The µC/OS-II kernel awareness allows you to display µC/OS-II's internal data structures in a convenient series of windows integrated with the C-SPY debugger. This provides you with information about each of the active tasks in the target application, about each semaphore, mutex, mailbox, queue and event flag group along with a list of all the tasks waiting on these kernel objects, and more.

• Support for debug modules from SoftBaugh
  Support for the debug modules USBP, USBP-PRO, and FETP from SoftBaugh has been added in the C-SPY FET debugger.

• Exporting command line for CSpyBat
  C-SPY now generates a file with helpful information that can be used to run the debugger from the command line using the CSpyBat utility. Every time the debugger is initialized (technically, it happens when a project is loaded and when terminating a debug session) a .bat file is generated that can be used almost without changes to start CSpyBat from the command line with the same settings as in the IDE.
  The file is generated as $PROJ_DIR$\settings\projectname.cspy.bat

3.41A 2006-04-13

Program corrections

• EW17848: Run to main did not work when main label was located in the upper memory on MSP430X devices.
• EW17847: The hardware was reset if the PC register was changed in the register window when a MSP430X device was used.
• EW17846: The status dialog box did stay for ever on the desktop during the flash erase programming if the erase or programming got disturbed (for instance by an reset).
• EW17843: The settings for the Stack plugin are now saved with each project, so it is possible to maintain different settings for different projects.
• EW17748: The simulator was stopped if the OSCOFF bit was set. This is not the case on a normal device.

3.40A 2005-12-19

Program corrections

• EW17425: The C-SPY setup macro execUserPreload() was incorrectly executed before the hardware was initialized which could generate the message 'Unknown exception in driver'.
• EW17417: The FET debugger now supports the MSP430F20x and MSP430F21x devices.
• EW17002: In debugger windows, bitfields are now shown with the correct value, instead of the value of the whole encompassing integer.
• EW16852: The simulation of the hardware multiplier in the simulator was incorrect.

New features

• Spy-Bi-Wire
  The 2-wire JTAG debug interface, also referred to as the Spy-Bi-Wire interface, is now supported by the C-SPY FET debugger. Spy-Bi-Wire works for the parallel port FET module and the TI USB FET module.
• Stack window
  To monitor the memory consumption and the integrity of the stack, a new Stack window has been added. It shows the stack contents as raw data, C/C++ variables, and function frames. It also shows current and maximum stack consumption graphically. Warnings can be issued when the stack exceeds a certain level or if the stack pointer points outside the stack memory.

• New breakpoint category - Log breakpoint
  Log breakpoints make it easy to log messages whenever execution passes a certain code location, without having to add any code to your application. When a log breakpoint is triggered, it displays a message in the Debug Log window and continues execution.

• New way to toggle breakpoints
  You can now set or clear a breakpoint by double-clicking in the left margin of the editor window where the breakpoint location is marked by a red X. If there is more than one possible breakpoint location in the source line, the breakpoint is placed on the first location.

• Attach to running target
  It is possible to attach the FET debugger to a running target without reseting the target. The FET debugger>Setup page now contains the additional optionAttach to running target. This option must be disabled when you download the application the first time. You can then stop the debug session, select the option and attach to your running target.
• Display of assembler variables
  By using the Show As command, available from the context menu in watch-type windows, you can select a different type interpretation of a variable than the one used by default. This command can be used on any variable, but typically, it is useful for assembler labels as they by default are treated as variables of type int.

• Trace
  A new trace mechanism is available in the simulator.

• Enhanced Memory Access Setup
  You can now set up memory access check automatically by using segment information from the UBROF input file. This set up can be made in the Memory Access Setup dialog box available on the Simulator menu.

• embOS C-SPY plug-in
  A C-SPY debugger plug-in for the embOS realtime operating system from Segger Microcontroller Systems is included in this release. The plug-in provides embOS awareness during debugging sessions and enables you to inspect the state of several embOS primitives such as the task list, resource semaphores, mailboxes, or timers. A MSP430 specific example application is also included in the installation folder 430\src\exampels\Segger\embOS. For more information see embOS plug-in for IAR Embedded Workbench.

• The Memory window now displays "--" for each individual memory unit that cannot be read-accessed, as opposed to the whole row.

• It is now possible to turn off the memory cache in the FET debugger. Select Disable memory cache available on the Project>Options>FET Debugger>Setup page.

3.30A 2005-04-18

Program corrections

• EW16146: The Advanced button in the Clock Control settings dialog had inverted functionality.
• EW16148: The Location field in the Watch window was not correct for a variable located in a register in the CPU register area (such as R15).
• EW16187: The pending bit is no longer automatically cleared for PORTx_VECTOR interrupts. The interrupt service routine must check the pending bit in the port register. It is also up to the interrupt service routine to clear the pending bit. Example:

  
  #pragma vector=PORT2_VECTOR
  __interrupt void Port_2(void)
  {
    if ((P2IFG & BIT0) != 0)
    {
      /* P2.0 triggered */
      P1OUT ^= BIT0;
    }
  
     P2IES ^= BIT0;
     P2IFG &= ~BIT0;
  }
  

• EW16327: Changing a variable in the watch window (after the emulator stopped on a breakpoint) could make the emulator crash.

• EW16371: Init new device in the Emulator menu did not reset the memory cache.

New features

• An update mechanism has been added which makes it possible to automatically update the firmware of the TI USB FET if necessary.

• Support has been added for the System Protection Module A (SPMA). The SPMA module provides read-out protection of internal resources, most notably of the internal program memory. This module is only available on TMS430 devices.

3.21A 2004-10-20

Corrected problems

• EW15385: The Break button on the Debugger toolbar could indicate that the debugger was still running even after the execution had completed.

• EW15672: The memory layout could not be loaded from the device description file on targets with memory zones smaller than 256 bytes because the cache page size was 256 bytes. The cache page size has now been changed to 128 bytes.

• EW15760: The lock bit (FCTL3.LOCK) was left at 0 even if it was 1 before a write operation. The value it had before the write operation will now be restored.

• EW15761: Writes to flash are done via a cache buffer in the debugger. This cache was only flushed to the actual flash on the target before step or go. If the debugger was shut down before any step or go had been performed, the values in the cache were not written to the flash memory. The cache is now flushed before the debugger shuts down.

• EW15762: When a memory write operation was made in the memory window in a write protected memory zone only a "bing" was heard. Now a warning message will be given.

• EW15887: Entering and leaving debugging mode could take longer and longer time for each mode change.

• EW15911: The "Retain unchanged memory" option could fail for devices with main flash memory starting at 0x1100.

• EW15921: When the C-SPY macro function __driverType() was used with the FET debugger, it incorrectly returned the value 1 when used with the "sim" string and 0 when the string "emul" was used.

• EW15939: In size limited variants of EW430, the debugger incorrectly counted also code originating from assembler source.

New features

• Support for TI USB FET interface module has been added in the C-SPY FET debugger.

• It is now possible to specify the Target VCC from the FET debugger options page.

• The target VCC can be displayed in the new Device Information window available on the Emulator menu.

• Editing memory in the Memory window now applies to a whole unit (8/16/32). When you start typing, an edit box appears with the contents of the part of the memory you are about to modify. The data is not written until the box is closed.

3.20D 2004-08-12

• EW15727: Even RAM and even INFO flash locations could not be modified using the C-SPY FET debugger with parallel port JTAG.

3.20A 2004-06-18

Program corrections

• EW14849: The C-SPY FET debugger could incorrectly report the error "Failed to read PC while stepping" while stepping/running when profiling was activated.

• EW15372: If the device was disconnected while the C-SPY FET debugger was running, the debugger got into an error state where you had to shut down the Embedded Workbench to recover.

• EW15442: The C-SPY FET debugger was not able to write to the information memory area if the option Retain unchanged main memory was used and the device only had 128 bytes of information memory.

• EW15552:Incorrect values was displayed in the Watch and the Live Watch windows when J-Link to connect to a development board with a MSP430F169.

New features

• EW14784: The __orderInterrupt() C-SPY macro was not returning an unique value.

• EW14844: Toogle breakpoint did not work in a debug project, if the source files did not have the same letter case in the Windows file system and in the make file. An additional breakpoint was set on the same location for each toggle attempt.

• EW14849: The FET debugger could report the error "Failed to read PC while stepping" while stepping/running when profiling was activated.

New features

• Smart display of STL containers at debugging
  Allows objects in STL containers to be viewed and manipulated.

• New auto-display debugger window
  Displays currently active variables and objects.

• Extended Clock Control
  Support for Extended Clock Control is now available on the Emulator menu. It makes it possible to control the available clocks on peripheral module level. This functional requires that Extended Clock Control is supported by the device.

• LCD display
  A LCD display window available on the View menu.

• Improved breakpoint configuration
  It is now possible to set breakpoints and to configure breakpoints, sequencer and state storage settings while the emulation is running.

• Forced Interrupt
  A new possibility to generate instant interrupts has been added to the C-SPY Simulator. The Forced Interrupt window available from the Simulator menu makes it possible to force an interrupt instantly just by selecting it in alist of all available interrupts and pressing a button.

• Trip cycle counter
  Two trip cycle counter registers have been implemented in the Register window. They can be used for measuring the number of cycles for a specific function or code sequence.

2.21B 2003-11-14

Corrected problems

• EW14635: The FET debugger could crash if a Step into command was followed by a Step out in a quick sequence.

New features

• It is now possible to make configurations to breakpoints, the state storage functionality and the sequencer during emulation.

2.21A 2003-10-17

Program corrections

• EW13634: The debugger will be forced to single step even if the use of virtual breakpoints has been turned off. This happens if the Run to option is enabled and all available hardware breakpoints are used. The debugger will then single step through cstartup to the specified location, causing the system start or a reset to take a very long time. The debugger will now ask you if you want to execute or stop at the first location. If you select execute, the debugger still is forced to singel step.

• EW14134: Setting breakpoints on CPU registers is not supported. Now, the simulator will report an error on an attempt to do so.

• EW14146: The size of a selection in the Memory window was incorrectly displayed in the status bar. This has been corrected.

• EW14192: Evaluating expressions containing recursive preprocessor macros (such as #define foo var.foo) could make the debugger freeze.

• EW14228: The simulator will now warn you about word access on an odd address. This can be turned off in a new simulator option page on the C-SPY options page.

• EW14282: A program error where unnamed union members were not properly displayed has been corrected.

• EW14444: The definition of ME2 in msp430f149.sfr has been corrected.

• EW14452: When the Reset button was hit in C-SPY, some instructions were incorrectly executed before the H/W was reset.

• EW14478: When the debug session starts, random values are now written to R4-R15 and to the RAM memory (specified in the DDF file) to make the simulator more hardware accurate. After a simulator reset, the program counter is initialized with the reset vector, the status register and cycle counter are zeroed and the SFR will be initialized with the values in the SFR file.

• A problem with register breakpoints has been corrected.

• The state storage settings are now saved between debug sessions.

New features

• The debugger will now by default leave the target system running when the debug session is closed. It is possible to change this behaviour by deselecting the Leave target running setting in the Emulator menu.

• The debugger will be forced to single step during system startup under the following conditions:
  • the Run to option is used
    
  • there are no hardware breakpoints available

  You will now be given the opportunity to select if you want to continue the execution or if you want to stop at the first instruction in this situation.

• Conditional breakpoints can now be set from the context menu the source and memory windows.

• A state storage snapshot functionality is now available in the state storage window. It updates the state storage window with the latest available information.

• It is now possible to edit the values in the stack window.

• The access condition for conditional breakpoints now also have a Read/Write alternative.

• It is now possible to define a bit mask for conditional breakpoints.

• Profiling is now available also in the FET debugger. The debugger must single step during profiling, this makes the debugger run very slow.

2.20C 2003-07-08 (patch release of 430proc.dll)

• EW14170: Singelstepping an interrupt handler could sometimes give an Application Error.

2.20A 2003-05-23

Program corrections

• None.

New features

• New breakpoint types
  It is now possible to set range breakpoints and conditional breakpoints on devices that support the Enhanced Emulation Module. For more information see User guide corrections.

• Combined breakpoints
  The Breakpoint Combiner makes it possible to combine breakpoints in order to define an exact situation where the execution should stop. This functionality is only available on devices that support the Enhanced Emulation Module. For more information see User guide corrections.

2.10A 2003-02-28

Program corrections

• EW13452: It was not possible to cast a assembler variable in the watch or quick watch window in a pure assembler project, for example like:

  (unsigned int *)#my_var
  

• EW13508: It was not possible to modify the cyclecounter.

New features

• Trace functionality
  The C-SPY FET debugger supports trace functionallity on devices that include the Enhanced Emulation Module.

• Sequencing functionality
  The C-SPY FET debugger supports sequencing functionallity on devices that include the Enhanced Emulation Module.

• Register window
  The register window now displays bit information when available. When a device description file is used, the memory mapped peripheral unit registers are also available in the register window.

• Interrupt simulation
  The IAR C-SPY simulator for MSP430 now simulates the individual interrupt enable bits in IE1 and IE2.

• Stack window
  A stack window has been added to the simulator. This window follows the top of the stack and lets you measure the stack depth.

2.09B 2003-01-31 (beta version)

• EW292: The Memory window contents was not updated after being changed by macros.

• EW245: 'Step'/'Step Into' failed to work properly in highly optimized functions.

• EW11710: Interrupt vector information was missing in a number of the device description files.

• EW12705: It was not possible to have a watch on the following defines:

  #define MAIN_CLOCK 2000000u
  #define MAIN_CLOCK 2000000uL

• EW13364: An error message "illegal expression" was received in the watch window when an expression with an offset to a pointer on the form pointer[offset] was used.

1.26B 2002-10-11

• None.

1.26A 2002-02-26

• EW11748: The default interrupt vectors are shown, if no interrupt vectors are given in the device description file.

• EW11647: The IAR MSP430 C-SPY did not correctly process the following instruction flow:

      CLR    R13
  ADD R13,PC
  

1.25A 2001-11-09

• None.

1.24A 2001-04-06

• 430DT0009: The simulator no longer reads a word from an odd address.

1.23A 2000-10-13

• 430DT0008: Interrupt vector tables in the MSP430_3xx.ddf files have been corrected.

1.22E 2000-06-20

• The CW GUI has been updated to version 2.31D.

• The V flag bit was not set to 1 when both operands were negative in the following XOR instruction
  
  c1=c2^c3;
  This has been corrected.
  [reference DT0004]

• All interrupt enable bits in the status register were not cleared after reset. This has now been corrected. [reference DT0005]
• It is now possible to use #SR in the Quick Watch dialog box or in macros. [reference DT0006]
• The instruction ADDC.B @SP+,3(SP) now increments the stack pointer SP by 2 as it should. [reference DT0007]

1.22A 1999-11-25

• A macro which traces stack usage has been added. See the file stack.mac.
• 430DT0003: The interrupt simulation now generates the correct interrupts, controlled by the corresponding enable bits.
• 430DT0002: Bitfield structs no longer cause internal errors when viewed in the Watch window.

1.20B 1999-02-22

• 430DT0001: C-SPY has now been corrected to adapt to the new behavior of ICC430 after the function call bug C0008 was corrected.
• The following system macros have been added:
  

  '__go'
  '__step'
  '__multiStep'
  '__autoStep'
  '__reset'
  '__calls'
  '__realtime'
  

  - see "Manual corrections and updates".


• Count value 0 is not accepted now by '__setBreak()' system macro [reference EW288]
• __setBreak() and __clearBreak() system macros have changed to return error status [reference EW265]
