Chapter 5. Installation and Testing
Enter the menu item number (0 to quit):
Tests for various hardware subsystems are provided, and some tests require special hardware in order to execute
normally. The Ethernet Configuration item may be used to set the board ethernet address.
Memory Tests
This test is used to test installed DDR SDRAM memory. Five different tests are run over the given address ranges.
If errors are encountered, the test is aborted and information about the failure is printed. When selected, the user
will be prompted to enter the base address of the test range and its size. The numbers must be in hex with no leading
“0x”
Enter the menu item number (0 to quit): 1
Base address of memory to test (in hex): 100000
Size of memory to test (in hex): 200000
Testing memory from 0x00100000 to 0x002fffff.

Memory test done.
Repeating Memory Tests
The repeating memory tests are exactly the same as the above memory tests, except that the tests are automatically
rerun after completion. The only way out of this test is to reset the board.
Repeat-On-Fail Memory Tests
This is similar to the repeating memory tests except that when an error is found, the failing test continuously retries
on the failing address.
Rotary Switch S1 Test
This tests the operation of the sixteen position rotary switch. When run, this test will display the current position
of the rotary switch on the LED display. Slowly dial through each position and confirm reading on LED.
