Hi Eric,

The main source of power for the EVM comes from the barrel jack input. You must first supply 20V to the barrel jack adapter to avoid having the dead battery flag set. You can read more about powering the TPS65988EVM in section 6.1 of the user's guide below.

Hi Eric,

What device are you using to source power to the EVM? To use the Type-C connector for powering the EVM, it must be configured properly as a sink first via the GUI. Could you ensure that you have it setup to be a sink? You can also download the latest GUI for the device from TI's website below.
