+Overview
+********
+
+The QCC744M Evaluation board features the QCC744M module, which contains a QCC744-2 SoC with 4MB of
+PSRAM and an external 8MB Flash chip.
+Qualcomm QCC74x is a tri-radio chipset integrating 1x1 Wi-Fi 6, Bluetooth 5.4,
+and IEEE 802.15.4 (Thread and Zigbee-ready) powered by a 32-bit RISC-V MCU up to 320 MHz, it is
+based on, and mostly equivalent, to the Bouffalolab BL61x Serie of chipsets.
+
+Hardware

+Supported Features
+==================
+
+.. zephyr:board-supported-hw::
+
+
+Serial Port
+===========
+
+The ``qcc744m_evk`` board uses UART0 as default serial port.  It is connected
+to the onboard USB Serial converter and the port is used for both program and console.
+
+
+Programming and Debugging
+*************************
+
+Samples
+=======
+
+#. Build the Zephyr kernel and the :zephyr:code-sample:`hello_world` sample application:
+
+   .. zephyr-app-commands::
+      :zephyr-app: samples/hello_world
+      :board: qcc744m_evk
+      :goals: build
+
+#. ``west flash`` cannot flash QCC74x MCUs at the moment.
+   You may first acquire 'QConn Flash' from the QCC74x SDK and follow these instructions:
+
+   * Open Qconn Flash
+   * Go to tab 'Flash Utils'
+   * Select appropriate flash port and interface.
+   * Reset board (press RESET, right button) while holding the BOOT (left) button to enter flash mode
+   * In 'Flash Program', browse to ``bsp/board/qcc744dk/config/boot2_qcc743_isp_release_v8.1.9.bin`` from the SDK and set the address to 0x0
+   * Press the 'Download' Button
+   * Enter Flash mode again
+   * In 'Flash Program', browse to zephyr.bin from your build folder and set the address to 0x2000
+   * Press the 'Download' Button again.
+
+   Your board is now flashed. Once the first binary has been flashed at 0x0, there is no need to re-flash it
+   unless the flash area containing it is erased.
+
+#. Run your favorite terminal program to listen for output. Under Linux the
+   terminal should be :code:`/dev/ttyACM1`. For example:
+
+   .. code-block:: console
+
+      $ screen /dev/ttyACM1 115200
+
+   Connection should be configured as follows:
+
+      - Speed: 115200
+      - Data: 8 bits
+      - Parity: None
+      - Stop bits: 1
+
+   Then, press and release RESET button
+
+   .. code-block:: console
+
+      *** Booting Zephyr OS build v4.2.0 ***
+      Hello World! qcc744m_evk/bl618m05q2i
+
+Congratulations, you have ``qcc744m_evk`` configured and running Zephyr.
