RH850‐U2B‐468PIN Sample and Demo hardware configuration - renesas/zephyr GitHub Wiki

Followings are hardware connection and test samples for Y-RH850-U2B-468PIN-PB-T1-V1, for more detail on how to setup hardware connection, please visit RH850/U2B 468pin User's Manual: Piggyback Board .

Default UART connection

HW	Configurations	Remark
UART0_TX	P02_6	UART channel 0 TX
UART0_RX	P02_5	UART channel 0 RX

The UART port can be accessed by connecting a USB-to-TTL converter to the UART0 TX and RX pins.

Flash command

• Before using the flash command, follow this guide to install the Renesas Flash Programmer (RFP) Host Tools.

• Then, use the following command to flash the code to the board:

  • west flash -- --tool-opt="-auth id FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF -osc 20"
