BQ40z50-R1 learning cycle

Hello,


I'm trying to get the bq40z50-R1 works with my batteries and it fails. The learning cycle is never performed (LStatus stay at 0x4) even though the REST flag is to one after each charge/discharge.

I've attached the log of a discharge at ~C/10.

The batteries are 3.7V 500mAh 4S1P lipo with LiCoO2+C chemistry. So I let the default chemid, but if somebody could check what is the best match it would be really helpful.

I've attached the dump of the dataflash to help debugging this issue. Is there any obvious configuration issue for my setup ?


Thanks,


Philippe
