When Windows XP (Service Pack 1) returns from hibernation, it cannot find the XJLink.

This is a problem with the Microsoft USB driver in XP Service Pack 1. There is a fix available from Microsoft Support - see KB article 331695 and KB article 822603 on their support site.

Using TEST_RESET to initialise JTAG devices

Some JTAG devices require a specific sequence of states to be applied to some signals in order to put the device into a JTAG-compliant mode. This application note describes how the TEST_RESET section can be used to describe the required sequence and control its application.

Non-standard cell types in BSDL files

Whilst the IEEE1149.1 (JTAG) standard defines certain standard cell types for use in JTAG devices, some manufacturers use non-standard cell types, in which case additional information is needed by XJTAG to use the devices. This application note describes how to identify such devices and supply the additional information to the XJTAG system.

What's the best way to run XJTAG on a remote computer?

XJTAG may not repond correctly if run remotely using telnet, so we recommend you use Remote Desktop or VNC instead.

Adding a custom GUI to XJEase or XJRunner

This application note describes how to interface XJEase or XJRunner with a graphical front end, creating a complete, customised JTAG test system. The examples given are for use with the XJDemo board (v1.2).

Can I run more than one version of XJTAG on the same computer?

You can install version 1.3.1.x alongside any older version of XJTAG: 1.0.x, 1.1.x, 1.2.x or 1.3.0.x.

How do I make sure my board has maximum test coverage?

We have produced a set of Design For Test (DFT) guidelines which explain what you need to take into consideration when designing your board, to make sure that as much of your board as possible is testable using JTAG.

I don't see any XJEase syntax highlighting/colouring in TextPad.

XJTAG installs the XJEase syntax definition files to the default directory for TextPad. However, your copy of TextPad may use a different folder instead.

To find out which folder is used in your copy of TextPad, click on the 'Configure' menu and select 'Preferences...'. In the Preferences dialog, select 'Folders' on the left-hand side and look for 'Syntax' on the right-hand side.

Now copy the XJEase syntax file into this folder. You can find the syntax file in your XJTAG installation directroy, in the 'TextPad' directory. Copy across all the files ending '.syn'
