User Guide
Read and Start Address
The Read control reads the flash memory on your board. To see the flash memory
contents, type a starting address in the Start address text box and click Read. Values
starting at the specified address appear in the memory table on the Flash tab.
Range
Displays the entire range of the flash memory. If you enter an address outside of the
flash memory address space, a warning message identifies the valid flash memory
address range.
Write
Writes the flash memory on your board. To update the flash memory contents:
■ Type in values in the memory table cells.
■ Press Enter, and click Write.
The application writes the new values to flash memory and then reads the values back
to guarantee that the memory table accurately reflects the memory contents.
Random Test
Updates the memory table with a random data pattern test. The test area is limited a
scratch page in the Unused block of flash memory (
Table A–1 on page A–1 ).
CFI Query
Updates the memory table with the CFI ROM table contents from the flash memory.
Increment Test
Updates the memory table with an incrementing data pattern. The test area is limited
a scratch page in the Unused block of flash memory.
Reset
Starts the flash device’s reset command and updates the memory table displayed on
the Flash tab.
Erase
Clears the Unused block of flash memory.
Flash Memory Table and Flash Memory Map
The control starting with the Address column allows you to write data in each cell.
The control underneath is read-only and displays the board’s flash memory map.
