Disable Charging - Boron

Hardware
1

Is it possible to permanently disable charging on the Boron? I understand there is an OS API call to disable charging but I would prefer to disable at the hardware or firmware level.
Thanks!

Unfortunately the charging pin is tied low. But it looks like you can write to the bq24195L and disable it in firmware:

Look at the line for pin 9 (Charge Enable)

Thanks Jared. Is what you are suggesting different than the pmic.disableCharging(); command? I am not familiar with writing to the bq24195L

Yup, that should do it. I haven’t tested it myself yet.
