Added bootloader backdoor configuration for cc2538DK in contiki-conf.h and selector in startup-gcc.c. Updated Makefile.cc2538dk to support direct uploading. Also updated the platform readme to include the workflow with cc2538-bsl.

On Windows, nodes can be programmed with TI's ArmProgConsole or the [SmartRF Flash Programmer][smart-rf-flashprog]. The README should be self-explanatory. With ArmProgConsole, upload the file with a `.bin` extension.

The CC2538 can be programmed via the jtag interface or via the serial boot loader on the chip.

On Linux, nodes can be programmed with TI's [UniFlash] tool. With UniFlash, use the file with `.elf` extension.

* Nodes can also be programmed via the serial boot loader in the cc2538. In `tools/cc2538-bsl/` you can find `cc2538-bsl.py` this is a python script that can download firmware to your node via a serial connection. If you use this option you just need to make sure you have a working version of python installed. You can read the README in the same directory for more info. (serial)

Strictly speaking, to build them you need to run `make TARGET=cc2538dk`. However, the example directories contain a `Makefile.target` which is automatically included and specifies the correct `TARGET=` argument. Thus, for examples under the `cc2538dk` directory, you can simply run `make`.
|
||||
|
||||
If you want to upload the compiled firmware to a node via the serial boot loader you need to manually enable the boot loader and then use `make cc2538-demo.upload`. On the SmartRF06 board you enable the boot loader by resetting the board (EM RESET button) while holding the `select` button. (The boot loader backdoor needs to be enabled on the chip for this to work, see README in the `tools/cc2538-bsl` directory for more info)

For the `cc2538-demo`, the comments at the top of `cc2538-demo.c` describe in detail what the example does.
