1. You definitely have a hardware problem.
2. When the hardware does not work correctly, it is possible that the error
is misleading.
3. Did you try running the tests by checking 1 test at a time??
4. *If* you want to troubleshoot the board and *if* the board is a TI XDS
560 emulator clone, you can debug it as a target board using a working
emulator. If you have the hardware skill and choose to do this, you can use
the following steps:
A. Locate a filter capacitor on the 5v board power. To do this you will
need to put the board in the end PCI slot [or use a PCI extender board if
you have one]. I will reference board locations from the component side of
the board with the PCI connector facing down. To the right side of the PCI
connector is one or more electrolytic caps. With the PC powered up, identify
the +5v and ground ends of the filter cap.
B. Remove power and take the board out of the PC. It will remain on the
bench for testing. Attach a wire to the +5v and ground leads of the
C. Locate the holes and mounting pads for a 14 pin "emulator connector"
[actually only 13 pins are used] near the top right of the board. Insert a
14 pin header on the component side of the board and solder it.
D. Attach the emulator cable to the 14 pin header.
E. Attach a +5v power supply to the 2 wires.
F. Bring up CCS and try to write/read from a few memory locations beginning
at 0x80000000 [internal data memory] Does it work??
G. Try to write then read from a few memory locations beginning at 0
[internal program memory]. Does it work??
