XJTAG version 2.6
A new major version of XJTAG – version 2.6 – is now available from our website for users who are in maintenance. […]
The Safe bitstream
The Safe bitstream gets mentioned occasionally in our documentation and warning/error messages and this blog post attempts to shed some light on what it is and what it’s used for. […]
Programming the TI MSP430 Microcontroller
Although it has a JTAG port, the TI MSP430 microcontroller is not a boundary scan capable device. Instead of the standard boundary scan registers there is a set of registers that allow the various functions of the device to be accessed and configured. […]
XJTAG version 2.5
The latest version of XJTAG, version 2.5, is now available to customers who are in maintenance. […]
Categorising devices in XJDeveloper – 10 rules of thumb
We asked one of the guys in-house who works with XJDeveloper most of the time to give some tips from his experience of setting up projects, and here is what he came up with: […]
Using CONNECT vs PULL in PDD files
Why use CONNECT not PULL for low-value pull resistors? When a resistor is specified as a pull resistor the XJTAG system will expect two things: […]
XJTAG Boundary Scan Testing with OMAP 35xx devices
Texas Instruments’ OMAP processors are becoming more and more popular. We have seen quite a few come through the office recently. The good news is that the OMAP processors do support boundary scan testing. […]
Debugging faults: always remember XJAnalyser!
The traditional technique for debugging printed circuit boards is to “observe” the state using oscilloscopes or multi-meters and deduce a fault. This method actually suppresses a very powerful engineering instinct that would help us a lot if we could only give it a better chance. […]
Debugging the Connection Test – part 4 (Logic errors)
With the new Logic support in XJTAG, the connection test can find more errors […]
Logic in XJTAG – capabilities and limitations
We see a lot of logic components used on boards that come through our office. Most often we see buffers, bus transceivers and devices of that nature, but also plenty of the usual discrete logic chips – simple gates, decoders, encoders etc. […]
