BQ Evaluation Software : Modifying Data Flash using GUI

Hi  ,

I am using the BQ34Z100 EVM with BQ Evaluation S/W , I am able to write to Control() from the data RAM screen but can't modify the Data Flash Contents , The following are the steps i took to modify data flash ,

To Modify Device Name : 

Default Value :bq34z100

Change to : aaa

1>>Click "Read All " button ,then click on the Device name and edit to "aaa"

2>>Press Enter (When i do press enter the default value appears back in red in the same place)

3>>Press Write all Button ,the DF task progress goes from 0-100% 2 times and writes flash ,but i'm not able to change any value in the DF screen

Please provide a solution ASAP.

Best Regards

Abhay
