Hello All,
I am facing binding error if I use UART1 for binding but UART0 is working fine. Refer the below error.
Please let me know the solution to solve this error.
Error:

Code:
#define UART_DEVICE_NAME "UART_1"
struct k_msgq* uart_init(void)
{
/* uart setup */
uart = device_get_binding(UART_DEVICE_NAME);
if(!uart){
return NULL; //-ENXIO
}
}
UART configuration in nrf9160dk_nrf9160_common.dts file.
&uart0 {
status = "okay";
current-speed = <115200>;
tx-pin = <29>;
rx-pin = <28>;
rts-pin = <27>;
cts-pin = <26>;

Thanks in advance!
