nRF9160 samples : undefined device names for device_get_binding

Question

Hello, 
 
 I'm using ncs 1.2.0 and trying to compile sample projects like v1.2.0
rf\samples\sensor\bh1749, also v1.2.0\zephyr\samples\sensor\* but all the defines for device label like "DT_INST_0_ROHM_BH1749_BUS_NAME" passed to device_get_binding() are unknown. 
 What's the proper way to define them in the project!. Should I make an overlay file where I define the communication peripheral....etc ? if yes, how can I link between lets say the SPI and the device ? 
 Regards,

Okay, it builds for me now, just had to change a few things. 1. First of all the .overlay file should have the same name as the board you're building for, so "nrf9160_pca10090ns.overlay". 2. Second, SPI1 will crash with UART1 on the DK by default, so it's easier to just avoid that one and use SPI3 instead. 3. And then in the .overlay file in your project, there were a few errors in the definitions of GPIO's. The overlay filed here works for me, just make sure to have the correct name. &spi3 { status = "okay"; cs-gpios = <&gpio0 13 0>; /* D10 */ sck-pin = <10>; mosi-pin = <11>; miso-pin = <12>; can1: mcp2515@0 { compatible = "microchip,mcp2515"; spi-max-frequency = <1000000>; int-gpios = <&gpio0 31 0>; /* D2 */ status = "okay"; label = "CAN_1"; reg = <0x0>; osc-freq = <16000000>; bus-speed = <125000>; sjw = <1>; prop-seg = <2>; phase-seg1 = <7>; phase-seg2 = <6>; #address-cells = <1>; #size-cells = <0>; }; }; / { aliases { can-primary = &can1; }; }; Best regards, Heidi
