1) The charger is not connected.  

2) All the GPIO including the MMC are 1.8V

Don,

Thanks again for the information.  I have updated the Overo I/O spreadsheet:

https://dev.bec-systems.com/redmine/bec/documents/show/1

Next batch of questions:

1) What pins on the PMIC are VSYSTEM connected to?  I'm trying to get
a better idea of the possibilities -- for example, can we use the
battery charger in the PMIC to charge a battery connected to VSYSTEM?
Perhaps we can use the USBH_VBUS as a charger input, but then there
are issues to work out such as how do we detect USB power, vs 5V AC
adapter for fast charging, etc.

2) docs mention all I/O is 1.8V.  Does this include things like
MMC/SD?  If not, can you define what I/O are not 1.8V.

Thanks,
Cliff
