BQ34Z100-G1: Parameter not writen. Class name xxx, Subclass name yyy, Parameter nam zzz ... A readback verification of this parameter failed.

Hi Ti experts

I have been playing around with the data flash memory from my MCU application and now the write access looks blocked with the BqStudio (1.3.101 Build)

This is what I am doing

• Reset the device and unseal it
• Bring it to Full Access
• Import a gg.csv file 
• Write All

The result of the writing is a readback verification failure, in particular during the CC Delta parameter.

Also if I am trying to change the chemistry the error code 1470 is reported.

Any idea of what it´s happening?

Many thanks
Juan
