Tip

When using this board with RIOT, set the BOARD variable to generic-cc2538-cc2592-dk in your Makefile. If you follow the standard RIOT project structure, your Makefile should look like this:

./Makefile

# name of your application
APPLICATION = hello-world

# Change this to your board if you want to build for a different board
BOARD ?= generic-cc2538-cc2592-dk

# This has to be the absolute path to the RIOT base directory:
RIOTBASE ?= $(CURDIR)/RIOT

include $(RIOTBASE)/Makefile.include

Support for the 3rd party CC2538-CC2592-DK board

Overview

The generic CC2538-CC2592-DK board can obtained from various vendors in the typical online shops. There are currently few options for readily available and affordable boards featuring a legacy CC2538 MCU; this is one of them.

The boards seem to be based on the schematics provided by @knowic via the CC2538_CC2592_DK repo.

Flashing

Prior to flashing the bootloader needs to be entered. For this, hold the “SELECT” button, press the “RESET” button, then release the “SELECT” button. Now run

make BOARD=generic-cc2538-cc2592-dk flash

Note: Flashing via J-Link would also be possible by passing PROGRAMMER=jlink, but requires attaching a J-Link programmer/debugger.

Accessing the terminal

The board features an CP2102 USB to UART bridge that is used for stdio by default. Just use

make BOARD=generic-cc2538-cc2592-dk term

Debugging

Assuming an J-Link (e.g. the J-Link EDU Mini) debugger is connected, debugging is as simple as:

make BOARD=generic-cc2538-cc2592-dk debug

Note: By default OpenOCD is used for debugging. While debugging works fine with OpenOCD, flashing is only supported via the bootloader or jlink.
