BQ34Z100-G1 Firmware Versions

Other Parts Discussed in Thread: BQ34Z100-G1

We are using a BQ34Z100-G1. The parts have 0100_0_06 firmware. The .gg being used is in the correct (older) format for the 0100_0_06 firmware. However, reading registers 0x10 & 0x11, current, via I2C always returns 0x0000. We were told that the newer 0100_0_16 firmware fixes this issue. We updated a part to the new firmware and it does address the issue. Now the issue is that there is not a compatible .gg.csv file for Battery Studio.

1. Is there a tool that converts a .gg to .gg.csv file that will be compatible with the newer firmware or does the whole golden image process need to be done over?

2. When using the 0100_0_06 firmware, is there is work around for reading registers 0x10 and 0x11?

3. Is there an SREC file available for 0100_0_06 if we want to downgrade back to the older firmware?

4. Other than the issue reading registers 0x10 and 0x11, is there a compelling reason to migrate to the 0100_0_16 firmware?

Thanks,

Cary

Hi Cary,

Sorry the two firmware versions were develop for two different SW tools. Thee shouldn't be that many parameters that needs to be updated. You can open the two files in a text editor and search for the parameters that need to be updated. We don't have an automated process to do this.

No we don't
No work around for version 06, the fix is in the version 16.
No SREC available with version 06, but EVSW version is available if needed.
I will have to check the build notes and get back to you, but seeing that you're going from 06 to 16 indicates there's a lot of improvements made.

Hi Damian,

Thank you for your answers. With respect to putting version 06 back onto a part, the method using EVSW will be appreciated.

Regards,

Cary

Hi Cary,

I will look into getting this information for you. Can you share why you want to revert to version 06, instead of updating version 16 with the version 06 parameters?

Hi Damian,

The design was finished the middle of last year and put on hold until recently. The issue with register 0x10 was why we looked into using the latest firmware. At this point I need to downgrade the boards used for testing the new firmware back to 06.

Regards,

Cary
