The Control Panel can be used to write/read data to/from the DDR2 SO-DIMM/Flash/SSRAM/
EEPROM memory on the DE4 board. Note, only the read function is supported on the flash
memory of the DE4 Control Panel. We will describe how the DDR2 SO-DIMM is accessed. Click
on the Memory tab to reach the tab-window shown in
Figure 3–8
.
A 16-bit value can be written into the DDR2 SO-DIMM memory by three steps, namely specifying
the address of the desired location, entering the hexadecimal data to be written, and pressing the
Write
button. Contents of the location can be read by pressing the
Read
button.
Figure 3–9
depicts
the result of writing the hexadecimal value 7EFF to location 0x100, followed by reading the same
location.
