Bq27510 Golden Image Programming over firmware

Hello,

if I have created a golden image.dfi file explained like in slua544.pdf it´s possible to write this file into flash without connecting with extern tools like bq Evaluation Software? I will to do this like the way I explain now.

1. In production I can write the .dfi file into flash of thy Microcontroller.
2. If firmware starts there is a production modus and now I write to the Bq27510 flash e.g.
   
   1. first I send unsealed key
   2. then I jump to the configuration subclass ID 48
   3. I can change the design capacity (I already do this)
3. Then I will copy .dfi file from µC flash and send this to the Bq27510 with th I2C interface.
4. Afterwards I delete .dfi file in µC flash

Now my questions to you.

Is this a possible solution or must the golden image file write to dataflash every time with external connection? Which command must be set before sending .dfi file to the Bq27510? Like CAL_MODE 0x0040? How large is the golden image file? I have found examples of 2kB size.

For us this would be a comfortable way to make the production of our device very easily.

Thank you for you answers

Best Regards

Eckart
