Custom SFR Window

It is now possible to define custom SFR’s (special function registers) in C-SPY with selectable access size and type.

Call Graph Window

A new Call Graph window has been added. It is browsable and displays all calls made to and from each function from any source file in the active project.

Macro Quicklaunch Window

The new Macro Quicklaunch window makes it possible to evaluate expressions and to launch C-SPY macros. The return value from the evaluated macro or expression is shown in a separate column and the user can re-trigger the evaluation at any given point.

Subversion

The version control integration has been extended with support for Subversion (SVN).

Latest Version: 2.30

H8SX Device Files and Debugger Support

IAR Embedded Workbench for H8 can be used with H8SX devices as this core is binary compatible with H8S. Therefore, device files and E10A-USB debugger support for H8X is now included. Note: The H8SX extended instruction set is not supported.

E10A-USB and E8a Debugger Improvements

Support for new devices, possibility to watch variables during program execution, and support for new breakpoint types are some of the C-SPY driver improvements.

64-bit USB Drivers

64-bit USB drivers have been added for E10A-USB and E8a.

Downloading Multiple Images with C-SPY

C-SPY is now able to download multiple images/applications at the same time. There is also a new debugger window called Images where you select for which application debug information shall be displayed.

Debug without Downloading

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

Edit Breakpoints

When you open the context menu from a row with one or more breakpoints, an entry Edit Breakpoint is now available. This will open the Edit Breakpoint dialog box that previously was available only from the Breakpoint window.

Auto Refresh in Memory Window

The C-SPY Memory window now has two new buttons on the toolbar. One button refreshes the window once and one button activates periodical refreshing of the window as long as the debugger is running.

Checksumming of Segments by Name

It is now possible to specify the name of a segment in a checksum command. This adds the start and end address of the segment to the range that is checksummed.

Updated Device Support

SFR header files, linker command files and device description files have been added for the latest Renesas devices including H8SX.

Information Center

An integrated navigation system that gives easy access to tutorials, product documentation, and example projects.
