New features and enhancements

Please see the Change Log for a list of new features and enhancements in XJTAG 3.4.

.NET Framework 4.5.2 and XJRunner Integration

XJTAG 3.4 is built against the .NET Framework v4.5.2. If you’re using the XJRunner Integration, you will need to target this version of the .NET Framework. A developer pack is available for Visual Studio 2012 and 2013 to develop against this version of the framework.

Windows XP Support

XJTAG 3.4 no longer supports Windows XP.

XJEase

Error if a JTAG scan is attempted in the reset sequence before the software knows the JTAG state.

It is now an error if a JTAG scan is attempted in the reset sequence before the software has been told the current JTAG state. In previous version it would
have assumed it started in “RESET” and not been an error.

The JTAG state can be set either via a TMS reset in the reset sequence, or a raw INJTAGSTATE statement in XJEase.

If the JTAG state is not set by the end of the reset sequence, the system will assume it to be in “RESET” before running any tests.

Maintenance Licensing

With XJTAG 2.4.9, the system now checks the maintenance status of the XJLink, and will not allow XJTAG releases available after maintenance has expired to run.

Supported Platforms

XJTAG is supported on both the 32 and 64 bit variants of the following operating systems: Windows Vista^® Service Pack 1 or 2, Windows 7^® Service Pack 1, Windows 8^®, Windows 8.1^® and Windows 10^®. Please upgrade to one of these operating systems before attempting to install XJTAG, and then apply the latest Service Pack for your operating system. Service Packs are available from the Microsoft Support website.

Support for Windows XP was dropped in this release.

XJTAG recommends a screen resolution of at least 1024×768.

Target Hardware

In order for XJTAG to interact with a circuit, the JTAG chain must be set up properly. To help with this, we have a produced a set of DFT guidelines. There is also a troubleshooting section in the help files.

Side-by-side installations

It is only possible to have one instance of each major release of XJTAG installed. It is possible, for example, to install any variant of version 2.5.x along side any variant of version 2.6.y; however it is not possible to install two variants of version 2.5, e.g. 2.5.6 and 2.5.7.

In order to allow users of the XJRunner COM interface to upgrade XJTAG without having to recompile their applications, the GUID for this component of XJTAG does not change with each major version of XJTAG.

Consequences: To use the XJIntegration COM object in side-by-side installations the correct version of the library must be selected when switching between versions. The Version Checker utility (XJVersion) that comes with XJTAG allows the registered version of the XJIntegration to be switched between installed versions.

Changing Project File Associations

By default, double-clicking on an XJTAG project file of any kind will open it in the most recently installed version of XJTAG. The Version Check utility (XJVersion) can be used to control these file associations. It is recommended to do this using the copy installed with the latest version of XJTAG that you have installed.
