BQ34Z100-G1: How to use Golden image file program?

Hi.

I made Golden Image file ,

The created image file must be merged into the FW of the MCU and programmed with I2C.

( 5. FlashStream® File Format in the (slua801) document.)

By the way, the MCU I am using is STM32F412RGT6 with SRAM 256KB and Flash 1MB.

I think the memory is small to program by merging the 180KB image into FW.

So, I hope we use the df.fs file with a smaller file size. Are there any problems?

Do SREC file and df.fs file, bq.fs file have the same effect? Which of the three files should I use?

What is the difference between programming the smallest df.fs file and programming the largest srec file?

thank you.

Hi,

Yes, there are difference between the files.

The .srec contains everything meaning if I upload your .srec to my gauge it will be in the exact same state as your when you created the .srec.

bq.fs and df.fs are listed below.

Generally, the bigger the file the more information in the file.

Hi.

What I'm curious is whether using the df.fs file and using the srec file are absolutely same for battery monitor operation.

Because of the file size, we will use df.fs file.

When using the df.fs file, is there a case where the battery monitor reads SOC incorrectly or reads remaining capacity incorrectly?

You said there is more information in larger files. Can you explain the difference between df.fs file and srec file?

thank you.

Hi,

The .srec has information not included in the df.fs such as the firmware. Typically, we send golden image files to customers to upload to the gauge. Please allow me some time to follow up with you on whether you can use the df.fs to flash the gauge or if there are any draw backs.
