@brief Support for the OpenMote-cc2538 board
|
|
|
|
## Overview
|
|
|
|
The [OpenMote](http://www.openmote.com/) is slim board that comes with a TI
|
|
SoC combining an ARM Cortex-M3 microcontroller with an IEEE802.15.4 radio.

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