Hi,

The easiest way to preserve data when updating the srec is as follows:

- Read the information that you would like to preserve before downloading the srec. The memory location of data flash settings is available in bqStudio:

- Download the srec file

- Write the values that need to be preserved back to the device

Regards,

Swami
