===============


|G520-G720-EVK| boards are evaluation kits of MediaTek |soc-mt8371| and 
|soc-mt8391| platform. These two SoCs are pin-to-pin compatible to each other
and they share the same evaluation kit design.

This section describes board features that are relevant to |IOT-YOCTO|.

FTDI Board Control
==================

The |G520-G720-EVK-REF-BOARD| has a FTDI FT232 chip connected to the UART0 port.
You can control the power (PWRKEY), reset (SYSRST), and download (KPCOL0) lines through the
CBUS lines of the FT232 chip:
