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 sits at a base address of
0x0800.0000. To see flash memory contents type the address above the base and values
starting at this address are displayed. Valid entries are 0x0000.0000 through
0x07FF.FFFF.
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 0x08FE.0000 to 0x08FF.FFFF (which
corresponds to address range 0x0000.0000 - 0x003FF.FFF 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 ).
