BQ28Z610EVM-532: Writing to the Data Flash with a microcontroller.

Part Number: BQ28Z610EVM-532


Hi,

i am implementing I2C communication between BQ and a microcontroler. So far i had no problems in reading data from RAM and MAC.

However, i am not able to write to the Data Flash. Technical Reference says how to write to DF :

so to update Design Capacity (address 0x462A) I am transmitting the following: 0x55 + 0x00 +0xAB+0x2A +0x46 + two bytes of new capacity value.

My BQ is in full access mode.

Can someone tell me where is my mistake and why writing is not possible? 

Is there any examples available on writing to the Data Flash with a microcontroller?
