BQ40Z80: GPCRB chem ID

Hi all,

Are the "Static Chem DF Checksum'' in the gg file and "Chem ID" corresponding? Does a chem ID correspond to a unique "Static Chem DF Checksum'" and will not change? Why is it mentioned in the GPCRB report "Please make sure that chem ID loaded in the GG file is the same as ID specified in the config‘’？Does "Static Chem DF Checksum'' depend on the model of the fuel gauge?

Sincerely,

Xiulan

Hello Xiulan,

"Static Chem DF Checksum'' may depend on the model of the fuel gauge. The report will have the above comment if specific internal values of the loaded chem ID are not within a specific expected range.

Hello shirish,

What do the specific internal values of the loaded chem ID refer to? In the gg file, what parameters are relevant for this?

Sincerely,

Xiulan

Hello Xiulan,

The chemistry ID is a set of values used by the gauge. You can think if it as a binary image. These values are not in the gg file.
