BQ40Z50: Fe-ion golden learning issue in BQ40z50

Part Number:BQ40Z50

Hi there，

We have a Fe-ion solution, the fuel gauge uses the BQ40Z50-R1, but the golden learning is not successful.

In contrast to the learning of the LI-ion cell, the parameter settings need to be set in LFP_RELAX，what other parameters need to be set?

Or is it possible for the Fe-ion itself to learn successfully?

Thank you!

BR，Eason
