RZA3UL‐SMARC Sample and Demo hardware configuration

Followings are hardware connection and test samples for RZ/A3UL-SMARC, for more detail on 1st setup hardware connection, please visit RZ/G2UL, RZ/A3UL, RZ/Five SMARC Module Board User's Manual: Hardware and RZ/A Getting Started with Flexible Software Package

Default HW configuration

HW	Configurations	Remark
SW11[1:4]	OFF, OFF, OFF, ON	QSPI boot (1.8V) mode
SW1-1	OFF	JTAG debug mode

The UART port is accessed by USB Type-microB Connector (CN14).
