# Enable the debug UART in the SoCCP

Enable and configure the debug UART instance in the SoCCP device tree.

1. Configure the debug UART instance in the SoCCP device tree.

    1. Open the device tree file:

dt_settings/soc/glymur_soccp/core/buses/qupv3-se.dtsi
            Copy to clipboard
    2. Configure the required serial engine as UART and set the baud rate.

        For example:

&qup2\_se7 {

compatible = “qcom,qup-uart”; // Change to i2c or spi for other serial engines
current-speed = <115200>;
status = “okay”;
};
    3. To disable the SoCCP debug UART, set the node status to `disabled` or delete the node.
2. Select the instance used for the debug UART.

    1. Open the board device tree file:

soccp_proc\zephyr\kernel\config\boards\soccp\glymur_soccp_board\glymur_soccp_board.dts
            Copy to clipboard
    2. Configure the console instance.

        For example:

chosen {

zephyr,sram = &ram0;
zephyr,console = &qup2\_se7;
};
3. Enable UART logging support.

    1. Open the configuration file:

/soccp_proc/core/config/prj_glymur_soccp_board.conf
            Copy to clipboard
    2. Add the required logging flag:

+ CONFIG_QC_LOG_BACKEND_UART=y
            Copy to clipboard
4. Enable serial driver support.

    1. Open the configuration file:

glymur_soccp_board_defconfig
            Copy to clipboard
    2. Add the required serial flag:

+ CONFIG_SERIAL=y
            Copy to clipboard
