CHAPTER 8: DEBUGGER

efl (erase flash memory)

Function

This command erases the contents of the ICE flash memory (including map information) and removes its protect function.

Format

 

efl

(direct input mode)

Example

>efl

Clear flash memory ... done!

>

Note

When erased by the efl command, all data in the flash memory is initialized at 0xff. Even when part of the data, such as a program, is thereafter written to the flash memory by the slf command, all other data remains unchanged (= 0xff). In this condition, the ICE cannot be operated in free-run mode. In order for the ICE to be operated in free-run mode, always make sure that after erasing the flash memory, all the data has been written into the flash memory.

In the ICE, furthermore, the default values for all option data are 0x00. Consequently, if you write to the flash memory before loading option data (lo command), the data you have written to the flash memory is overwritten by 0x00.

GUI utility

[File Flash Memory Operation…] menu item

When this menu item is selected, a dialog box appears allowing selection of flash memory operations.

To execute the efl command, select "Erase flash memory" from the [Operation] list box and then clock [OK].
