OpenThread on CC2538 Example

This repo contains example platform drivers for the Texas Instruments CC2538.

The example platform drivers are intended to present the minimal code necessary to support OpenThread. As a result, the example platform drivers do not necessarily highlight the platform's full capabilities.

Toolchain

Download and install the GNU toolchain for ARM Cortex-M.

In a Bash terminal, follow these instructions to install the GNU toolchain and other dependencies.

$ cd <path-to-ot-cc2538>
$ ./script/bootstrap

Building

In a Bash terminal, follow these instructions to build the cc2538 examples.

$ cd <path-to-ot-cc2538>
$ ./script/build

Flash Binaries

If the build completed successfully, the elf files may be found in <path-to-cc2538>/build/bin/.

To flash the images with Flash Programmer 2, the files must have the *.elf extension.

$ cd <path-to-cc2538>/build/bin/cli/ot-cli-ftd
$ cp ot-cli-ftd ot-cli-ftd.elf

To load the images with the serial bootloader, the images must be converted to bin. This is done using arm-none-eabi-objcopy

$ cd <path-to-cc2538>/build/bin/cli/ot-cli-ftd
$ arm-none-eabi-objcopy -O binary ot-cli-ftd ot-cli-ftd.bin

The cc2538-bsl.py script provides a convenient method for flashing a CC2538 via the UART. To enter the bootloader backdoor for flashing, hold down SELECT for CC2538DK (corresponds to logic '0') while you press the Reset button.
