+Realtek RTS5912 Evaluation Board
+################################
+
+Overview
+********
+
+The RTS5912 EVB is a development platform to evaluate the Realtek RTS5912 embedded controller.
+
+.. figure:: rts5912evb.webp
+   :width: 800px
+   :align: center
+   :alt: RTS5912-GR EVB
+
+Hardware
+********
+
+- Realtek-M300 Processor (compatible to Cortex-M33)
+- Memory:
+
+   - 384 KB SRAM
+   - 64 KB ROM
+   - 512 KB Flash(MCM)
+   - 256 B Battery SRAM
+- PECI interface 3.1
+- FAN, PWM and TACHO pins
+- 6x I2C instances
+- eSPI header
+- 1x PS/2 ports
+- Keyboard interface headers
+
+For more information about the evb board please see `RTS5912_EVB_Schematics`_ and `RTS5912_DATASHEET`_
+
+The board is powered through the +5V USB Type-C connector or adaptor.
+

+
+Programming and Debugging
+*************************
+
+Building
+========
+
+#. Build :zephyr:code-sample:`hello_world` application as you would normally do.
+
+#. The file ``zephyr.rts5912.bin`` will be created if the build system can build successfully.
+   This binary image can be found under file "build/zephyr/".
+
+Flashing
+========
+
+#. Connect Dediprog into header ``J81`` and ``J82``.
+#. Use Dediprog SF600 programmer to write the binary into the external flash ``U10`` at the address 0x0.
+#. Power off the board.
+#. Set the strap pin ``GPIO108`` to high and power on the board.
+
+Debugging
+=========
+
+Using SWD or JTAG with ULINPRO.
