Connect the equipment as the following:
Scope Channel SC#4: BUCK
Depopulate the /CE Pull-up jumper and ensure the TS jumper is placed for fixed TS resistor. Turn ON the supply PS#2, then turn ON the supply PS#1. The VSYS will rise to the level of 4.5V. BUCK should rise to the level of 1.85V. The device will begin to charge as long as the TS is left at default configuration and there are no other faults.
To adjust the charge current or change other parameters, connect the USB2ANY to the EVM and then startup TI Charger GUI.
