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. […]
