BQ34z100G1学习成功后，导出gg文件修改update status为0x02后，再写入gg文件出现错误

I suspect either the value you are entering is out of range which is more likely to give an error like Value is beyond maximum value defined for parameter, or the supply voltage is too low.
CC Delta is the gain factor for calibrating Sense Resistor, Trace, and internal Coulomb Counter (integrating ADC delta sigma) errors. It is used in the algorithm that reports charge and discharge in and out of the battery through the Remaining Capacity register.
