Can not modify the parameters in data flash

Other Parts Discussed in Thread: BQEVSW

Hello Battery Management Community:

 

I’m using and studying the bq34z110EVM board with bqEVSW. I followed the “Design Steps” and ran a complete cycle.

 

Later, I was going to modify a parameter in data flash, input a new value, pressed the enter, but the parameter changed back to the previous value and the Input field turned red. Following pictures:

step1:     

step2:     

step3:     

I’m sure that the device was not set to be sealed. What can cause this issue?
