The OpenMote can be used with an "OpenBase" which provides an RJ-45, 2 x USB mini ports, a JTAG header, and two pin headers which provide access to the microprocessor pins. For example, the pins labelled DOUT/DIN provide access to the UART Tx/Rx respectively. This UART is connected to the "USB_FTDI" port via an FTDI FT232RQ UART/USB driver chip.
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
To flash via USB, connect the "ON/SLEEP" pin to ground, and reset the board into the bootloader by pressing the reset button ("BUT1"). Then call "make flash" from your application directory.
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
make flash
from your application folder.
Mac OS users may experiment a command line expecting connect. Just type it and the process will continue.
