Group B: Memory Tests
B1
TXP Scratchpad
The Group B tests verify all memory blocks of the
QLogic 8400/3400 Series adapters by writing various
data patterns (0x55aa55aa, 0xaa55aa55, walking
zeroed, walking ones, address, and so on.) to each
memory location, reading back the data, and then com-
paring it to the value written. The fixed data patterns are
used to ensure that no memory bit is stuck high or low,
while the walking zeroed/ones and address tests are
used to ensure that memory writes do not corrupt adja-
cent memory locations.
