If the target memory system is configured, this should
write abcd1234 to memory starting at 0 and then read back
the same values.
M>
• Returned value is equal to the written value implies that memory is
working.
• Returned value is not equal to the written value implies that memory
control may not be initialized. Try to initialize by:
M>cf reset=run;rst;w 5
#waiting for 5 seconds...
U>b
M>
• Repeat above memory test.
• Check memory access size using the mo command:
M>mo
• Check access size matches target memory -a0. The default access size -a0
is the 64-bit access.
M>mo -d4 -a0
• Repeat above memory test.
