BQ40Z50: Modify rows in SREC-Files

Part Number: BQ40Z50
Other Parts Discussed in Thread: BQSTUDIO

Hello guys,

is it possible to modify "firmware"/SREC-File?

I dont want to override calibration and lifetime data by uploading of a new .srec with new parameters.

I know to modify paramerers with sequential import with .gg.csv but its nessesary to make it less complicated.

Which addresses/rows in the SREC file are for calibration, lifetime, black box and sbs configuration and can it just be deleted?

best regards

Hi Martin,

The SREC file is more like a binary file and is not for customers to change directly.

I would suggest you use the bqStudio to update calibration data and then generate a new srec file again.

I guess you misunderstood my concern.

In der TRM at cap 14.16 is a table with Data Flash Summary.

The srec file format build of type, count, address, data, checksum.

Is there a relation between these address?

Hi Martin,

Unfortunately, the format of a srec file is proprietary. I would still suggest you use bqStudio to make any changes.
