 The OpenMote-CC2538 has a mini JTAG 10-pin male header, compatible with the `SmartRF06` development board, which can be used to flash and debug the platforms. Alternatively one could use the `JLink` programmer with a 20-to-10 pin converter like the following: <https://www.olimex.com/Products/ARM/JTAG/ARM-JTAG-20-10/>.

+The serial boot loader on the chip is exposed to the user via the USB interface of both the OpenUSB and the OpenBase carrier boards. The OpenUSB carrier board is capable to automatically detect the boot loader sequence and flash the CC2538 without user intervention. The OpenBase carrier board does not have such feature, so to activate the bootloader the user needs to short the ON/SLEEP pin to GND and then press the reset button.

+If you are compiling for the OpenMote-CC2538 Rev.A1 board (CC2538SF53, 256 KB Flash) you have to pass `BOARD_REVISION=REV_A1` in all your `make` commands to ensure that the linking stage configures the linker script with the appropriate parameters. If you are compiling for older OpenMote-CC2538 revisions (CC2538SF53, 512 KB Flash) you can skip this parameter since the default values are already correct.

 The `PORT` argument could be used to specify in which port the device is connected, in case we have multiple devices connected at the same time.
 
 To generate an assembly listing of the compiled firmware, run `make openmote-demo.lst`. This may be useful for debugging or optimizing your application code. To intersperse the C source code within the assembly listing, you must instruct the compiler to include debugging information by adding `CFLAGS += -g` to the project Makefile and rebuild by running `make clean openmote-demo.lst`.
