Programming and Debugging
*************************
Applications for both the ``nrf54h20dk/nrf54h20/cpuapp`` and
``nrf54h20dk/nrf54h20/cpurad`` targets can be built, flashed,
and debugged in the usual way. See :ref:`build_an_application`
and :ref:`application_run` for more details on building and running.
Applications for all targets can be built and flashed the usual way.
See :ref:`build_an_application` and :ref:`application_run` for more details on
building and running. Debugging is for now limited to the application and radio
cores only, using :ref:`nordic_segger`.
