One potential cause of damage to an XJLink2 JTAG controller is transient current spikes caused when a board is first powered on and the decoupling capacitors are charged. We’ve talked about this issue on the blog before and shown that, unfortunately, even a very brief spike in current can cause damage to the controller. Introducing [...]
XJTAG 4.0 introduced Optimised Scans, providing more options for configuring JTAG chains and improving scan speeds. To assist debugging any problems getting chains to run when deploying projects using these new features into a production environment, JTAG Chain debugger has also been given an update: if run in a system with an XJRunner licence, the [...]
In XJDeveloper and XJInvestigator, the ways in which you can interact with the list of screens have been improved. […]
XJDeveloper 4.0 now has a brand new modern look to the Boards screen with 3 possible display modes: Tile mode, Row mode and Grid mode. The new interactive tile and row controls dedicate more screen space to each board so the data can be presented in a clearer, more readable display. […]
In XJTAG 4.0, you are now able to rearrange the tabs in XJRunner so that you can see output from multiple XJLinks at once. The tabs also display more information about the corresponding XJLink than in previous versions of XJTAG. […]
In previous versions of XJTAG the JTAG chains in the circuit were all operated at the same frequency. Because the Optimised Scans feature in v4.0 now allows a different frequency to be set for each chain, some changes to the user interface were required, and as a result the chain frequency settings in the user [...]
Optimised scans is a new feature added to XJTAG 4.0 and it provides a number of improvements aimed at increasing test speed. With Optimised Scans enabled, every JTAG TAP will scan data through at a separate frequency based on the capabilities of the JTAG devices in that TAP group. […]
A new version of XJTAG – version 4.0 – has been released, containing major updates and new features. It is now available from our website for users who are in maintenance. […]
