Device tree error undefined reference to `__device_dts_ord_127'

[drumpros]

Hi there,

i have built a custom board in devicetree. I have based it off the nrf52840DK dts but added in a magnetometer:

s3_mini_v1.dts

i am attempting to configure the magnetometer, however when ever i try to get the device instance for the magnetometer, i receive the following error at compilation.

\lsm303agr_m\src\main.c:120: undefined reference to `__device_dts_ord_127'

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

\lsm303agr_m\src\main.c:120: undefined reference to `__device_dts_ord_127'

This only happens when i call any functions that require me to pass a device instance. I have tried referencing the magnetometer with different macros, but this has not fixed the issue. i can also return parameters such as 'label' or 'status' from the magnetometer but i cannot get the device instance. if i comment out the line:

    if (!device_is_ready(m_lsm_dev))

and also:

    i2c_reg_read_byte(m_lsm_dev, LSM_TWI_ADDR, 0X1E, &data);

then it will compile.
