Flash Memory
Programmer
Using the control panel, you can perform the following operations to read
from and write to the board’s flash memory:
■
Erase the entire flash memory
■
Write one byte to flash memory
■
Read one byte from flash memory
■
Write a binary file to flash memory
■
Load the contents of the flash memory into a file
When performing these transactions, consider the following
characteristics and limitations of the flash memory:
■
Erasure of the entire flash memory is required before you can write
new data
■
Flash memory tolerates only a limited number of erasures

Do not exit from the control panel while erasing the entire
contents of the flash memory; this takes about 2 minutes.
