6.3.4. The Flash Tab

The Flash tab allows you to read and write flash memory on your board.

Figure 19. The Flash Tab

The following sections describe the controls on the Flash tab.

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 the base address of 0x1000.0000. 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 0x0FFF.FF80.

Note: If you enter an address outside of 0x0000.0000 to 0x0FFF.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.

Note: To prevent overwriting the dedicated portions of the flash memory, the application limits the writable flash memory address range to 0x0FF80000- 0x0FFFFF80 (which corresponds to address range 0x0000.0000-0x00080000 in the uppermost portion of the user software memory block).

Increase

Start an increase data pattern to test flash memory.

Random

Starts a random data pattern to test flash memory.

CFI

Reset

Erase

When erasing flash memory contents should read FFFFFFFF, which is limited to a scratch page in the upper 512K block.
