Flashing and Debugging

Currently RIOT supports flashing the OpenMote using a Segger JLink JTAG adapter or via USB, using the bootloader on the board.

Flashing via USB

RIOT support flashing with USB by default.

make flash

You may have to specify the flashing port with PORT_DEV=<my_openmote_port> make flash

The flash tool needs to convert the generated Hex file to RAW format. For this it needs to have the intelhex library installed.

apt install python3-intelhex


pip3 install intelhex

Flashing via JTAG

To be able to flash the board via JTAG you need to install Seggers JLinkExe tool. Once you have this in place, you can simply flash by calling

PROGRAMMER=jlink make flash

from your application folder.

macOS users may experiment a command line expecting connect. Just type it and the process will continue.


The JTAG interface is required for debugging. On some board revisions the debug may not be able to run. To debug use:

make debug


file  board.h
 Board specific definitions for the OpenMote-B board.
file  gpio_params.h
 Board specific configuration of direct mapped GPIOs.
file  periph_conf.h
 Peripheral MCU configuration for the OpenMote-B board.
