Read
The Read control reads the flash memory on your board. To see the flash memory
contents, type a starting address in the text box and click Read. Values starting at the
specified address appear in the table. The flash memory addresses display in the
format the Nios II processor within the FPGA uses, that is, each flash memory address
is offset by 0x0800.0000. Thus, the first location in flash memory appears as
0x0800.0000 in the GUI.
1 If you enter an address outside of 0x0000.0000 to 0x07FF.FFFF flash memory address
space, a warning message identifies the valid flash memory address range.
Write
The Write control writes the flash memory on your board. To update the flash
memory contents, change values in the table and click Write. The application writes
the new values to flash memory and then reads the values back to guarantee that the
graphical display accurately reflects the memory contents.
1
To prevent overwriting the dedicated portions of flash memory, the application limits
the writable flash memory address range to 0x0FF8.0000 to 0x0FFF.FFFF (which
corresponds to address range 0x07F8.0000 - 0x07FF.FFFF in the uppermost portion of
the user software memory block, as shown in
Figure 6–1 on page 6–1 and Table A–1
on page A–1 ).
Random Test
Starts a random data pattern test to flash memory, which is limited to a scratch page in
the upper 128K block.
CFI Query
The CFI Query control updates the memory table, displaying the CFI ROM table
contents from the flash device.
Increment Test
Starts an incrementing data pattern test to flash memory, which is limited to scratch
page in the upper 128K block.
Reset
The Reset control executes the flash device’s reset command and updates the memory
table displayed on the Flash tab.
Erase
Erases flash memory, which is limited to a scratch page in the upper 128K block.
Flash Memory Map
Displays the flash memory map for the DSP Development Kit, Stratix V Edition.
