XJTAG released the latest update to its software suite, with focus on increased flexibility, easier access to full JTAG capabilities and maximum test coverage.
Dynamic chain profiling makes it easier to initialise boards with multiple JTAG chains, in which a device in one JTAG chain controls power supplies or reset lines for JTAG devices in the other chains.
During flash programming it is now much easier to set up XJTAG to only clock JTAG data through the chain that is needed for the programming operation, leaving the other chain(s) held in their current state. In some situations this can remove the need to clock hundreds of bits of data per-scan, and can significantly speed up testing/programming.
In addition, the XJLink2 JTAG controller lets the user describe connections from the XJLink2 to the PCB under test.
