Voltage Measurements with XJLink2

8 February, 2010

One of the exciting new features of XJLink2 is the ability to measure a number of voltages. Via the 20way XJlink2 connector you can measure up to 18 different voltages. This means supply rail voltages can be measured before (and during) JTAG testing, and analogue measurements are now simple to make during your tests.

XJLink2 button and LEDs

5 January, 2010

The new XJlink2 has a button and some LEDs, which aren’t found on most JTAG interface devices. These are simply there to make life a little simpler on a crowded workbench. Once you have a project open in XJRunner you can start testing by just pressing the button – this can be quicker than finding your mouse which has at some point almost certainly moved off the on-screen Run button.

Using XJEase functions in XJRunner tests

7 December, 2009

A frequent question from customers is, “Why is my new XJEase test function not listed when I create an XJRunner test?”

XJEase Functions

For a function to be eligible to be made available to XJRunner it must be in the main project (.xje) file or a device file, or in a code file specified either in the main project (in the Circuit Code Files Screen) or from within a test device file (in the Test Device Files Screen).

Integrating XJTAG with other Test Systems – XJTAG API

30 November, 2009

XJAPI is a simple interface that gives low-level access to the JTAG chain via the XJLink. It is intended to allow programmers the ability to integrate the XJTAG hardware into other test systems.

The XJTAG installation includes example projects in C/C++ and C# demonstrating the use of the API. The C# example is easily adapted for use in VB.net if the C# interop wrapper class is compiled into a class library. The examples are installed in the XJTAG Shared Files folder in a folder called ‘XJAPI Examples’. XJTAG installs a shortcut to the XJTAG Shared Files folder in its Start Menu group.

The installation also includes a complete reference for the API.

XJTAG Support

9 November, 2009

Help us to help you!

If you need to let us know about a problem that you are having with XJTAG there are a few things that you can do help speed up the support process.

There are a few stock responses that we have to give repeatedly to many support requests. If you are reading this then you may well have received them in the past yourself. The first thing that we will generally ask you to do is upgrade to the latest version of the tools; these can be downloaded from XJTAG Downloads. You will need your maintenance user name and password to gain access to this section of the website. If you are not sure of these details then email support@xjtag.com and we will be glad to send you a reminder email.

If you are using the latest version of the tools then we will need as much information as you can provide to help us to resolve your problem. This includes:

  • The version of the tools you are using
  • The version of the operating system (e.g. Windows XP Service Pack 3)
  • A detailed description of the problem or issue you are facing
  • Is it reproducible? If so, what steps are needed to reproduce it?

In many cases it helps us to diagnose your problems faster if we have your XJTAG project as well as your description of the problem you are having. The best way to send us all of the files is to use the Export option from the File menu in XJDeveloper. From this menu you can tell the system to create a .ZIP archive of all of the files that make up your project.  By using XJDeveloper to pull all of these files together you make sure that no files are missed.

If we have all the information early on in the support process along with your project, we are much more likely to be able to resolve the issue quickly.

If the tool you are using is crashing then it will create a crash report and then give you the opportunity to send that to us. Please do send this report to us as it contains a lot of useful information. We may still need to ask you for more information; however if you go through these steps before contacting us then we should be able to help you resolve your issue faster.
