+Overview
+********
+
+The Canaan CanMV-K230 is a development board with a Canaan Kendryte K230
+64bit RISC-V SoC.
+
+Programming and debugging
+*************************
+
+Zephyr binary can be loaded by U-Boot command in machine mode.

+.. code-block:: console
+
+   fatload mmc 1:1 0x0 zephyr.bin
+   go 0x0
+
+Applications for the ``canmv_k230`` board configuration can be built as
+usual (see :ref:`build_an_application`) using the corresponding board name:
