RZG2UL‐SMARC Sample and Demo hardware configuration

Followings are hardware connection and test samples for RZ/G2UL-SMARC, for more detail on 1st setup hardware connection, please visit RZ/G2UL Group User's Manual: Hardware and RZ/G2L, RZ/G2LC, RZ/G2UL, RZ/G3S Getting Started with Flexible Software Package

Default HW configuration

HW	Configurations	Remark
SW11[1:4]	OFF, OFF, OFF, ON	Boot mode 3(QSPI Boot (1.8V) Mode)
SW1-1	OFF	JTAG Debug mode

By default, J-Link RTT Viewer is used by Zephyr running on CM33 for providing serial console. The only serial port (SER3_UART micro-USB) is reserved for CA55 to run Linux.
