I am trying to implement the Ws2812 driver on the NRF5340 based on the driver example.
The specific error I am getting is:
c:/sysgcc/arm-eabi/bin/../lib/gcc/arm-none-eabi/10.3.1/../../../../arm-none-eabi/bin/ld.exe: zephyr/drivers/spi/libdrivers__spi.a(spi_nrfx_spim.c.obj):(.rodata.__compound_literal.1+0x0): undefined reference to `__device_dts_ord_68'
This is similar to this post:
Implementing WS2812 Driver NCS (undefined reference to `__device_dts_ord_61')
It seems like there is something missing in the configuration.
prj.conf:

Nothing in the other linked post seemed to help.
