Memory Module Tests
The following entries explain the commands, parameters, and
error messages for each memory module test.
Floating 1/0 Memory Test
The floating 1/0 memory test writes floating 1 and floating 0
across one location in RAM. To run the floating 1/0 memory
test, type
t 3/mem/float10
[ address ] [ bank ] and press Return.
When you type the floating 1/0 memory test, replace the
optional
address
parameter with a specific address at which
you want to start writing 1s. The default address is A0100000.
Floating 1/0 memory test error messages
The only floating 1/0 memory test error message is
?TFL: 3/mem/float10 (Err=
N
, which indicates that the floating
1/0 test failed.) The N represents the number of errors the
memory module reported.
