Hi there,
I've been developing nicely with the nrf52840SDK board for a while now.
I am trying to create a custom board now for our development PCB using nRf52840 micro.
I created a new board with nrf52840 as the SoC and then created an overlay file with all my peripherals.
Seems to build ok, but when I try to get a pointer to a device node, GPIO, SPI etc I get errors such as...
FAILED: zephyr/drivers/spi/CMakeFiles/drivers__spi.dir/spi_nrfx_spim.c.obj

The devices seem to be picked up as shown here..
and they are included in the compiled device tree output file...

in main.c I am trying to get pointers to device nodes..
#include <zephyr/zephyr.h>
#include <zephyr/kernel.h>
#include <drivers/gpio.h>
#define DISPLAY_NODE DT_ALIAS(flashrst)
#define MYSPI_NODE DT_NODELABEL(spi1)
struct gpio_dt_spec display_reset = GPIO_DT_SPEC_GET(DISPLAY_NODE, gpios);
void main(void)
{
const struct device *spiDev; /* SPI device pointer*/
/* Get the SPI device handle*/
spiDev = DEVICE_DT_GET(MYSPI_NODE);
if(!device_is_ready(spiDev))
{
return;
}
//else
//{
/// printk("Device is ready %s\n");
//}
//printk("Hello World! %s\n", CONFIG_BOARD);
/* check devices are ready: Could make this a function?*/
}
but getting build errors.
When I look at the .dts file
it seems to have none of the nodes defined and gives me warnings for compatible property like so..
the file is below and has nothing after &flash0 node
I'm sure it should!!
/dts-v1/;
#include <nordic/nrf52840_qiaa.dtsi>
/ {
model = "SB_Wearable";
compatible = "cubik-innovation-,sb-wearable01";
chosen {
zephyr,sram = &sram0;
zephyr,flash = &flash0;
zephyr,code-partition = &slot0_partition;
};
};
&flash0 {
partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
boot_partition: partition@0 {
label = "mcuboot";
reg = <0x0 0xc000>;
};
slot0_partition: partition@c000 {
label = "image-0";
reg = <0xc000 0x72000>;
};
slot1_partition: partition@7e000 {
label = "image-1";
reg = <0x7e000 0x72000>;
};
scratch_partition: partition@f0000 {
label = "image-scratch";
reg = <0xf0000 0xa000>;
};
storage_partition: partition@fa000 {
label = "storage";
reg = <0xfa000 0x6000>;
};
};
};
What am I doing wrong please?
Many thanks
