Hello developers,
I would like to know what is wrong with open thread examples, literally tired of trying now. Firstly my two FTD sensor nodes are not able to reconnect, so i thought to again start with a demo example and build the example. Than i face this issue as mentioned in headline. I have been using nRF connect SDK from past 2 months have developed solutions using USB CDC and also using I2C. So it's not like i don't know how to interface USB CDC or I2C using NCS.
I would like to know how can i enable USB CDC in the open thread examples. Here is my normal sensor example, were i am just reading the i2c address of the sensor and printing on terminal.
Simple Code:

return;
}
const struct device *gpio_dev1;
gpio_dev1 = device_get_binding("GPIO_1");

gpio_pin_set(gpio_dev1, 8,1); // 1--- off
while (1) {
//printk("Hello World! %s\n", CONFIG_ARCH);

i2cscanner();

}
}
And here is my proj.conf for the same.
proj.conf
CONFIG_GPIO=y
CONFIG_SERIAL=y
CONFIG_I2C=y
CONFIG_I2C_1=y
CONFIG_NEWLIB_LIBC_FLOAT_PRINTF=y
CONFIG_USB=y
CONFIG_USB_DEVICE_STACK=y
CONFIG_USB_DEVICE_MANUFACTURER="DnK"
CONFIG_USB_DEVICE_PRODUCT="S_Node_test"
CONFIG_USB_UART_CONSOLE=y
CONFIG_UART_INTERRUPT_DRIVEN=y
CONFIG_UART_LINE_CTRL=y
CONFIG_UART_CONSOLE_ON_DEV_NAME="CDC_ACM_0"
The above example easily runs smoothly without any error. But whenever i try to add the same example in Open thread client server examples. How can i do that ? If i debug the program in open thread it gives me hard fault error after execution of this statement uart_line_ctrl_get(dev, UART_LINE_CTRL_DTR, &dtr); in the below program. I am doing all the experiment on the NCS demo examples itself, haven't invented anything by myself.
Below is the code where i am trying to use USB CDC in my coap server example.

So can somebody please provide me the code snippet how to use this peripherals in open thread. My whole open thread development is halted thanks to this.
