Hello There,
I have created a new Board type in device tree based off of the NRF52840DK board, but i have added an i2c peripheral:
proto139.dts

I am trying to fetch the board config using device_get_binding() as shown in the main.c:
`#include <zephyr/devicetree.h>
#include <zephyr/kernel.h>
#include "lsm303agr_reg.h"
#include <zephyr/logging/log.h>
#include <zephyr/device.h>
LOG_MODULE_REGISTER(foo, CONFIG_LOG_DEFAULT_LEVEL);
#define DT_I2C0_N DT_PATH(soc, i2c_40003000)
#define DT_LSM303_CN DT_CHILD(DT_I2C0_N, gpio_10)
/* void get_dt_dev(const struct device* i2c_dev)
{
} */
void main(void)
{
const struct device *i2c_dev = DEVICE_DT_GET(DT_NODELABEL(lsm303agr));
const struct device *i2c_dev = device_get_binding(DT_LSM303_CN);`
as shown above, i have tried two different methods to retrieve the config and both return the following error:
`build\zephyr\include\generated\devicetree_generated.h:13643:40: error: 'DT_N_S_soc_S_i2c_40003000_S_gpio_10' undeclared (first use in this function); did you mean 'DT_N_S_soc_S_i2c_40003000_S_gpio_10_ORD'?
13643 | #define DT_N_NODELABEL_lsm303agr DT_N_S_soc_S_i2c_40003000_S_gpio_10
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
`
my prj.config is shown below:
`CONFIG_GPIO=y
# choose RTT console
CONFIG_UART_CONSOLE=n
CONFIG_USE_SEGGER_RTT=y
CONFIG_RTT_CONSOLE=y
# Config logger
CONFIG_LOG_BACKEND_RTT=y
CONFIG_LOG=y
CONFIG_LOG_DEFAULT_LEVEL=4
# Configure sample logging setting
CONFIG_LOG=y
CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y
CONFIG_I2C=y
CONFIG_I2C_NRFX=y`
any help would be much appreciated
Thanks
