HPM5301EVKLITE
==============

Overview
--------

HPM5301EVKLite is a development board based on Xianji's entry-level high-performance MCU HPM5301. HPM5301EVKLite provides a USB Type-C interface for high-speed USB-OTG functionality, with onboard buttons and LEDs for convenient user interaction. It also provides an extension interface that is compatible with Raspberry Pi and a standard JTAG debugging interface.

Console information printing
----------------------------

By default, UART0 is used for console printing. Connect UART0.TXD (J3.36) and UART0.RXD (J3.38) externally through the USB to serial port tool.
