                http://www.kpitgnutools.com/phpmyfaq/index.php?aktion=artikel&rubrik=009001&id=495&lang=en

            5. Projects built in KPIT Eclipse IDE can be easily debugged in HEW. KPIT Eclipse provides a feature to launch HEW for debugging.

CHANGES IN THIS RELEASE:

The enhancements in the KPIT Eclipse v2.2 release are as follows:

            1. Hardware debug support for RX and SH targets
                In order to debug your application on RX hardware targets via an E1/E20 JTAG interface or on SH hardware targets via an E10A-USB JTAG                 interface you must install the corresponding Windows device drivers first. Typically these drivers are installed by the HEW IDE installer that                 was supplied on a CD with your development kit or emulator hardware. In the event of any problems installing these drivers, please contact                 either your distributor, Renesas tools support or the KPIT GNU Support team for assistance.

            2. Extended HEW debug feature support is added. Pre-configured HEW workspaces have been added for few targets; RX600/RX610, SH7211,                 SH7264 to extend the HEW debugging feature. This will allow you to directly download and debug project (built in KPIT Eclipse) in HEW                 environment.

The issues fixed in the KPIT Eclipse v2.2 release are as follows:
            1. The 'Debug Configuration' view generates null pointer exceptions when no project is selected. The issue is now fixed.
            2. The local variables are not visible in the 'Watch' window while debugging the GNUH8 projects in KPIT Eclipse. The issue is now fixed                 in the GNUH8 v10.01 toolchain.
            3. The KEEP() attribute cannot be used per section; instead, it has to be used per group. This issue is now fixed.

The issue fixed in the KPIT Eclipse v2.2 maintenance pack 1 release is as follows:

            1. For all newly created RXC/SHC/GNURX/GNUSH projects using KE v2.2, HardwareDebug' is set as active configuration by default. However, at                 times, the output (abs/.x) files were generated into the 'Debug' directory rather than the 'HardwareDebug' directory. Also, the 'Debug' build                 configuration was found to be set as active, while the debug configuration was looking for the output file (.x) file in the 'HardwareDebug'                 directory. The issue is now fixed.

The issue fixed in the KPIT Eclipse v2.2 maintenance pack 2 release is as follows:

            1. The KE v2.2 failed to launch if it was installed with Japanese support feature. The issue is now fixed.

KNOWN LIMITATIONS:

This section describes the known limitations in this release on Windows platform. We intend to fix these limitations in future releases.

            1. The known limitations in the linker script wizard are listed below:

                a. Groups/sections are added or modified to get the start address type as 'Label'. However, when moved up or down using the 'Move up'                 or 'Move down' buttons, data gets corrupted and the wizard behaves incorrectly.
                Workaround: In such cases, please click 'Cancel' instead of 'Apply' to go back to the previously saved data and condition.
                Alternatively, delete all sections from the GUI editor and specify the sections in the linker user options.

                b. While modifying the address of a group, user is not allowed to delete the preceding '0x'.

                c. The memory region feature is not provided in this release for GNU tools.

                d. While adding or modifying a group's start address from 'Follow on from previous group' to 'Label', the group does not get added or                 modified if the last label (e.g. _stack) is selected for GNU tools.

            2. The software update feature is unavailable in this version due to limitations in platform configuration.
                Please visit the following link for details,
                http://kpitgnutools.com/phpmyfaq/index.php?aktion=artikel&rubrik=009001&id=483&lang=en 

            3. When the user attempts to change the build phase settings, however does not change any settings ultimately and clicks "OK" or "Apply"                 rather than "Cancel", the project re-builds on selecting "Build". This is native behaviour of Eclipse.

            4. When 'Optimization for access to external variable' is set to 'Inter-module' option i.e., when late optimization is set to the working project                 and if one or more files are modified, the complete project will be re-built rather than only the modified files, in both the first and the                 second build phase passes.

            5. When compiler 'Output file type' is set as 'Preprocessed source file (*.p/*.pp)' or 'Suppress #line in preprocessed source file (*.p/*.pp)', the                 compiler generates the preprocessed file with an '.obj' extension rather that *.p/*.pp for *.c/*.cpp files.
                This results in linker error:"** L2200 (E) Illegal object file "

            6. For imported projects, 'Debug' is set as the active configuration by default. Please set the required active configuration manually. To change                a configuration click on 'Project' -> 'Build configurations' -> 'Set active' -> 'Debug/HardwareDebug/HewDebug/CustomDebug/Release'. The                KPIT Eclipse RX and SH samples can be debugged on hardware. Please note that the configuration needs to be changed to 'HardwareDebug'                after importing the samples. Also, the path of GDB needs to be set under 'Run' -> 'Debug Configurations' -> 'SH/RX Hardware Debugging :                 <current configuration name> -> 'Debugger' tab.

            7. The 'Debug' icon in the toolbar can be used to invoke debug sessions for hardware debug by default. If the workspace contains only projects                 with 'Debug using HEW' / 'Simulator Debug' as default configurations, a dialog box showing following debug options is displayed;
                    - HEW Debugging
                    - SH/RX Hardware Debugging
                    - Simulator Debugging
                Please select "HEW Debugging" and HEW will be launched. Pre-configured workspaces have been added for few targets; RX600/RX610,                 SH7211, SH7264 to extend the HEW debugging feature. This will allow you to directly download project (built in KPIT Eclipse) in HEW                 environment. Alternatively, right click on the project and select 'Debug As'->'HEW Debugging'. This will launch HEW for debugging.

            8. Debug configuration for debugging using GDB simulator has been provided in KPIT Eclipse for SH /RX targets. However, debugging                 feature for simulator debug has limitations for projects created using Renesas RXC toolchain in KPIT Eclipse IDE.

Known Issues: Eclipse CDT 5.0.1:

The following are the known issues in Eclipse CDT 5.0.1. These issues are also present in KPIT Eclipse v2.2.

            1. Exception on opening the debug-modules tree: In the debug perspective, the tree view for "<project_name>.x" module gives an exception,                 when clicked on the 'Modules' tab. This error occurs the first time a project is debugged. Later, the label gets populated and only then, the                 files are visible.

                Please refer to the following bugs:
                https://bugs.eclipse.org/bugs/show_bug.cgi?id=250929
                https://bugs.eclipse.org/bugs/show_bug.cgi?id=247274

            2. The error 'mi_cmd_var_create: unable to create variable 'object' occurs repeatedly during debug. This error is observed in Eclipse CPP                 runtime, when the variables(which are not accessible at the breakpoint while debugging and which are defined at some other location in the                 source code) are added in the watch window. This error can be fixed by deleting the particular variable from the watch window.

                Please refer to the following bug:
                https://bugs.eclipse.org/bugs/show_bug.cgi?id=182206 

            3. Warnings are displayed after the debug session is terminated. Similar warnings are observed with the native CPP runtime using the native                 GDB.

            Note :
            (*) For Windows Users:

            1. The KPIT Eclipse v2.2 supports integration with Renesas SHC toolchains (v9.0.0 onwards). However, Renesas SHC toolchains with versions                 lower than v9.3.0 are not officially supported in KPIT Eclipse v2.2.

            2. KPIT Eclipse v2.2 supports integration with Renesas RXC toolchains (v1.0.0 onwards).

                Important: KPIT Eclipse v2.2 supports integration of Renesas SHC and RXC toolchains on the Windows platform only, and not for the Linux                 platform. This is because these toolchains are not available for the Linux platform.
