We understand that sometimes (for your own sanity if nothing else) you need to test that your test equipment is working. For this reason, it is possible to run a health-check on XJLink2 hardware (and XJLink2-based hardware) using the self-test feature available in the XJLink Manager. The self test can be run with or without a loopback connector but should never be run with the XJLink connected to test hardware. […]
XJlink2 comes with a detailed self test program. Accessed via the “Test…” button in XJLinkManager this enables you to run a diagnostic report on your XJlink2. […]
We all pay close attention to the termination of high speed signals, especially clock signals. However in many of the designs I see this doesn’t seem to have happened for the JTAG clock signal TCK. But TCK is a clock signal just like any other clock signal. […]
One of the exciting new features of XJLink2 is the ability to measure a number of voltages. Via the 20-way 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 is the only JTAG interface that can accurately measure frequency. […]
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. […]
The new XJLink2 USB-to-JTAG interface is beginning to make its way out to our distributors and depending on where you are is, or shortly will be, available for trial and purchase. […]
This post outlines what is new in the 2.3 release. Some aspects will be explored in more detail in future entries. […]
