Why does the XtremeDSP Development Kit-IV Built In Self-Test (BIST) reset test fail on some newer computers?
The same test will pass when the XtremeDSP Development Kit is placed in another computer.
There is a known race condition issue between the software and hardware that causes the XtremeDSP Development Kit-IV non-RoHS BIST reset test to fail on some faster computers. The Reset is not broken unless you see DMA failures. If the DMA tests pass, the reset failures can be safely ignored.
You can disable the Reset Test by:
1. Selecting the Advanced button next to the LED, Resets, Oscillators, and host interface test.
2. Unchecking the box next to Test Rests in the dialog box.
3. Clicking the Ok button.
NOTE: The race condition between software and hardware was addressed with the release of the RoHS compliant board, and the XtremeDSP Development Kit-IV RoHS version should not have this reset test failure.
