Hello,
in reference to an ongoing issue, see here: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1285673/bq34z100-soc-jumps-rfrom-7-to-100-to-0
We changed the Firmware for this BQ34Z100-G1 to the Firmware recommended: 0.16, after some bugs occured with the FW2.01 for -R2.
We use ChemID 2100, as per the GPC_report attached. ChemID was issued under FW 2.01 on BQ34Z100-G1 (see old issue).
The datasheet of the used Battery is attached as well.
After changing to FW 0.16, Update Status won't change from 05 to 06. Logfiles, Logerrors and CSV of DataTables are attached as well.
