Have you taken a look onto your JTAG signals? Are you using RTCK (on ARM)? Have you configured it properly? Have you configured the system and JTAG reset behaviour properly? Did you know that an not properly terminated JTAG signals (especially pull-up and pull-down resistors and reset connection) can cause LOTS of problem in the field even when JTAG never seems to be used? Do you use the same scan loop also for other devices on your board? Are those devices' JTAG signals connected in parallel or correct serial order? Did you configure such scan loop for your BDI? And why don't you tell us which processor you are using? >> The BDI2000 is perfectly scriptable with expect, so what are you >> missing? > > The ability to make it fit in the bed of nails.

You could use another JTAG debugger, probably a much smaller device like the Rowley CrossConnect Light. With best regards Andreas Schweigstill -- Dipl.-Phys.
