Known Issues

• SDSCM00014440: CCS does not accept relative paths for loading workspaces in shortcuts
• Component: Code Composer IDE
• Target: All
• Release Note: CCS changes the current working directory during startup, so command line references to Workspace files must be qualified
• Work Around: Use a path relative to C:\ccstudio_v3.3\cc\bin, or an aboslute path. For example:



C:\CCStudio_v3.3\cc\bin\cc_setup.exe -i C:\CCStudio_v3.3\drivers\import\arm7tdmi_big.ccs -startCCS C:\Projects\arm7sim.wks 

• SDSCM00014180:  h2t and t2h examples do not run on C64+ of DaVinci (DM6446) connected via Rev D JTAG in HS RTDX mode
• Component: Installer
• Target: C5500
• Release Note: HS-RTDX fails to work on XDS560 Rev D cable with a TCLK rate of 35 MHz.
• Work Around: To enable HS-RTDX run with a TCLK rate of 30 MHz instead of 35MHz. The clock rate can be modified in CCS Setup


• SDSCM00016113: Include the cache differences option in Memory Window in CCS 3.3
• Component: Memory Window
• Target: C6000
• Release Note: C67X Customers that need to use the "cache bypass" and "highlight cache differences" features that were provided for C67X emulation targets by the memory window in CCS 3.1 can do so by opening the legacy memory window
• Work Around: The old memory window can be accessed as follows, once the target is connected:
• Select View / GEL Toolbar from the CCS Menu.
• Enter GEL_OpenLegacyMemoryWindow(0x0000) into the GEL toolbar. This will open a CCS 3.1 style memory window at the address passed in as a parameter (0x0000 in this example).
• You can right-click on this window and select Properties, which will display a dialog box that has the settings for cache bypass and highlight cache differences.


• SDSCM00017025:  No longer able to view register pairs in the register window
• Component: Register Window
• Target: C6000
• Release Note: Users may not be able to view registers in long or double format on C6000 devices.
• Work Around: Users can utilize the old CCS Register Window in order to view the register pairs by using the GEL command 'GEL_OpenLegacyMemoryWindow("Core Registers"). On some targets the associated register group may be "CPU Registers" instead of "Core Registers."


• SDSCM00017747: CCS Crashes when performing operations through PDM
• Component: Code Composer IDE
• Target: All
• Release Note: Performing multiple connect/load program/disconnect operations from the PDM on devices with 6 or more cores can cause CCS to crash
• Work Around: None


• SDSCM00017777: CCS crashes when too many control windows are open
• Component: Code Composer IDE
• Target: All
• Release Note: CCS may become unstable and crash when too many control windows are open for multi-core targets
• Work Around: This issue is due to Windows resource limitations. To prevent it from occurring please ensure that less than six control windows are open at any given time. Also, ensure please ensure that all unnecessary control windows are closed. Alternately, users can alter their Windows Register to increase the resource allocation for Windows programs. Instructions explaining how to do so can be found here.


• SDSCM00017999: Profiling of single non-CPU event returns -1 for profiled data
• Component: Profiler
• Target: All
• Release Note: Selecting a single event for profiling that is neither the CPU.cycle event nor the Cycle event may cause the profiler to report incorrect event counts after profiling.
• Work Around: To ensure that profile events are properly configured and collected please ensure that at least two events are selected for any given Profiling run.


• SDSCM00018146: Unable to load GEL files from the command line as current directory gets changed
• Component: Code Composer IDE
• Target: All
• Release Note: CCS changes the current working directory during startup, so command line references to GEL files must be qualified
• Work Around: Use a path relative to C:\ccstudio_v3.3\cc\bin. For example:

  C:\ccstudio_v3.3\cc\bin\cc_app.exe .\..\gel\alais.gel

• SDSCM00018389: c55x+ is not removed from the scan chain if connection fails.
• Component:C55x+ Driver
• Target: C55x+
• Release Note:After a connection fails (no target power, DSP in reset, etc.) a C55x+ device will be no longer accessible, and CCS will need to be restarted
• Work Around: None
