BQ78350: VCT time and capacity value location in R3 FW

Tool/software:

Hi, 2 years ago I got help with tuning the VCT for a small size LiFePO4 battery. Then we where on FW version 2.02. Now we have FW version 3, and data memory locations have changed. Can you provide me with the new adresses? These are the values I am referring to:

For FW version 2.02, the window parameter is at address 0x4627, 1 byte, in units of seconds. 40 seconds default.

The minimum taper charge is at address 0x4623, two byte integer in units of 1/256mAh

Both the Current Taper Window and the Minimum Taper Charge are at the same addresses for FW 2.02 and FW 3.0

Thank you very much for confirming!

A question I think I know the answer to: Is there a way these values can be shown in BQ studio by for example a new .bqz file? Right now it's kind of tricky, using BQ studio you must use advanced communications to view the current values. Using a CSV import does not change these values so you can easily overlook these settings.

They are hidden in bqStudio on purpose. You'd have to get a .bqz file that makes these values public, which I can't provide on E2E. Do you have a TI FAE contact locally? If so, they can get you this file.

Thanks for your reply! Much more than I expected. We don't have a TI FAE contact locally. I should contact technical support for this?
