I am working on a school project and need to set up SPI communication between a wiznet,W5500 and the nRF54L15DK. I can build and run my program but I am getting no responce when I ping the device. When looking over my prj.conf I have a warning associated to CONFIG_ETH_W5500=y that says
CONFIG_ETH_W5500 was assigned the value y, but got the value n. Missing dependencies:
DT_HAS_WIZNET_W5500_ENABLED.
Here is the prj.conf
# Networking config CONFIG_NETWORKING=y # w5500 driver config CONFIG_SPI=y CONFIG_NET_L2_ETHERNET=y CONFIG_ETH_W5500=y # Network address config CONFIG_NET_CONFIG_SETTINGS=y CONFIG_NET_CONFIG_NEED_IPV4=y CONFIG_NET_CONFIG_MY_IPV4_ADDR="192.168.101.52" CONFIG_NET_CONFIG_PEER_IPV4_ADDR="192.168.1.1" # choose RTT console or UART console CONFIG_SERIAL=y CONFIG_UART_CONSOLE=y CONFIG_CONSOLE=y CONFIG_USE_SEGGER_RTT=n CONFIG_RTT_CONSOLE=n # General config CONFIG_LOG=y CONFIG_LOG_DEFAULT_LEVEL=3 CONFIG_NET_LOG=y
Here is the overlay

}Currently just trying to make the warning go away but also wondering why I can't ping the device.
