3.2.2 DEBUG Function Circuit
In order to facilitate users to debug, the base board is equipped with a USB to UART chip. Using generic USB
cable to connect the J3 to PC, it will help to use the USB serial port on the PC directly. The default serial debug
port of Halley5 is UART3_RXD and UART3_TXD of GPIO PC group.
