Part Number: BQ27510-G3
Other Parts Discussed in Thread: AM3358, , BQSTUDIO

Tool/software: Linux

Hi ,

I am using Battery Management Studio.Here are the my steps,

1) Open Battery Management Studio and auto detect battery fuel gauge IC. -SUCCESS

2) calibrate current ,voltage ,temperature,board offset.-SUCCESS

3) Write date registers to fuel gauge. -SUCCESS

4) Now create golden /bqfs/dffs file - Error (ROM Packet checksum mismatch ).

I don't know why error comes.

OR any another method to write calibration register without bqfs/dffs/.

AM3358 I2C1 connect to BQ27510-G3 I2C.

Can you use bqstudio and an ev2300 to do all this steps which you just listed so we see if you have the same packet checksum mismatch.
I suspect you the checksum mismatch may have come at the point of writing data registers to the gauge. How were you able to determine that writing to the gauge was succesful? if you disconnect power from the gauge and then reconnect again, are you able to read the correct data you changed in df?

thanks

Yes... I am using bqstudio and ev2300. Read and write data I am not getting any error, but when create a golden image then I am getting error. 512 registers read while creating a golden image.

Yes, when I reset or power cycle gauge I can able to read latest calibrated value. But I an not able to create golden image.

Is there any C application that I can write register in gauge that I changed. Like battery capacity, Board offset, current, voltage and temperature calibration value.

I am using AM3358 and Linux. Once I get calibrated value from bqstudio than in production I write that value thru C application.

EV2300 - Version 3.1c & BQ27510-G3

the ev2300 is the problem. You are using an older firmware version. You need to update the firmware on the device to something more recent. Use the attached firmware. It has instructions on what to do.

Thanks.. I don't have two EV2300. Is it possible single with EV2300.?

Hi Onyx...Is there any C host application which I can calibrate fuel gauge. Meaning thru I2C is it possible to calibrate current,voltage. We need to calibrate only current ,voltage and change battery capacitor.
