The TMDSHSECDOCK
180-pin docking station is available for purchase through Texas
Instruments. The docking station is a baseboard that enables rapid prototyping.
There is a power switch on the docking station that determines whether power to the
control card will be supplied by the 5V connector or USB connector.
Note: The docking station power switch
must to be toggled to the EXT-ON side to meet the power requirements of the
AM263x Control Card. EXT-ON indicates that the power is being sourced from the
Barrell connector of the Control Card Dock. The mini-USB (USB-ON) connector does
not meet the power requirements of the AM263x Control Card.
The AM263x
Control Card has a power mux (TPS2121RUXT) that will supply power from the type-C
connection as long as the voltage supplied by the type-C connection is equal to or
greater than the voltage supplied by the HSEC docking station. Therefore, if both a
type-C connection is present and the control card is connected to a powered HSEC
docking station, then the power mux will rout the type-C supplied voltage to VMAIN
of the control card. If there is no type-C connection and voltage is being supplied
through the HSEC docking station then the power mux will route that voltage to VMAIN
of the control card.
