By default, RIOT will attempt to flash the MCU via the USB UART using a Python script named cc2538-bsl. Hold down the SELECT pushbutton while pressing RESET to activate the MCU's internal bootloader, then run:
make flash
Some Linux machines may not recognize the CC2538DK's vendor and product ID automatically. If a /dev/ttyUSBx device does not appear, try specifying these codes to the FTDI driver manually:
echo 0403 a6d1 > /sys/bus/usb-serial/drivers/ftdi_sio/new_id
RIOT will use /dev/ttyUSB1 by default, but if the UART is given a different device name, you can specity it to RIOT using the PORT variable:
make PORT=/dev/ttyUSB2 flash
To flash using a Segger JLink JTAG adapter you need to install Segger's JLinkExe tool, then specify PROGRAMMER=jlink when flashing:
make PROGRAMMER=jlink flash
