Hi，
In the NCS V2.3.0 version, I successfully obtained the serial device through the following code and compiled it
But when I get the serial device in the same way in NCS V2.6.1, there is an error and I want to know what causes this?
static const struct device *const uart0_dev = DEVICE_DT_GET(DT_NODELABEL(uart0)); static const struct device *const uart1_dev = DEVICE_DT_GET(DT_NODELABEL(uart1));
