Tip

When using this board with RIOT, set the BOARD variable to same54-xpro in your Makefile. If you follow the standard RIOT project structure, your Makefile should look like this:

./Makefile

# name of your application
APPLICATION = hello-world

# Change this to your board if you want to build for a different board
BOARD ?= same54-xpro

# This has to be the absolute path to the RIOT base directory:
RIOTBASE ?= $(CURDIR)/RIOT

include $(RIOTBASE)/Makefile.include

Support for the Microchip SAM E54 Xplained Pro board.

Overview

Flashing the device

Connect the device to your Micro-USB cable using the port labeled as DEBUG USB.

The standard method for flashing RIOT to the same54-xpro is using edbg. by calling: make BOARD=same54-xpro -C tests/leds flash

Note that on Linux, you will need libudev-dev package to be installed.

Users can also use openOCD to flash and/or debug the board using: PROGRAMMER=openocd make BOARD=same54-xpro -C tests/leds flash

On Linux you will have to add a udev rule for hidraw, like

bash
echo 'KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0664", GROUP="plugdev"' \
    | sudo tee -a /etc/udev/rules.d/99-usb.rules
sudo service udev restart
