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 0x07FE.0000 to 0x07FF.FFFF (which
corresponds to address range 0x00FE.0000 - 0x00FF.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 a 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 Arria V GX FPGA Development Kit.
