Chapter 9: Testing Target System Memory
Memory Test Patterns

Recommended Test Procedure

Two types of tests are offered for testing target memory: oscilloscope tests,
and memory functionality tests.
Oscilloscope Tests
1. Connect the oscilloscope to view activity on the bits of interest.
2. Start an Oscilloscope Read (see page 108) or Oscilloscope Write (see page
109) test, as desired.
The test activity will be written onto the bits you specified continuously until
you cancel the test.
Use both the Oscilloscope Read test and the Oscilloscope Write test to
thoroughly check the connections of interest.
Memory Functionality Tests
1. Run the Basic Pattern (see page 99) test on the entire Memory Range.
Result:
• No Problems. Perform the Address Pattern (see page 102) test next.
• Problems found. Refer to "If problems were found by the Basic Pattern
test" on page 100.
2. Run the Address Pattern (see page 102) test on the entire Memory Range.
Result:
• No Problems.
• Problems found. Refer to "If problems were found by the Address
Pattern test" on page 103.
If no problems were found by the Basic Pattern test and the Address Pattern
test above, you can ignore the rest of the tests. The memory in your system
has been tested thoroughly and it is good.
