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 from 0x03FE.0000 to 0x03FF.FFFF (which
corresponds to the unused flash memory address range shown in
).
Random Test
Starts a random data pattern test to flash memory where the data pattern contents are
read back and displayed. Errors are reported in the messages window. This test takes
10-15 seconds to run with an hour-glass displayed while the test is busy.
Increment Test
Starts an incrementing data pattern test to flash memory where the data pattern
contents are read back and displayed. Errors are reported in the messages window.
This test takes 10-15 seconds to run with an hour-glass displayed while the test is
busy.
CFI Query
The CFI Query control updates the memory table, displaying the CFI ROM table
contents from the flash device.
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 Stratix IV E FPGA Development Kit.
