NRF5340 with W5500 weird ping behaviour

[Stefano6]

Hello,

I have a problem with my nrf5340 in combination with the w5500. I have everything working but the connection is not stable.

I have nothing in the main.c

void main(void)
{
}

This is my nrf5340dk_nrf5340_cpuapp.overlay file

&spi3 {
	compatible = "nordic,nrf-spim";
	sck-pin = <8>;
	miso-pin = <10>;
	mosi-pin = <9>;
	cs-gpios = <&gpio0 11 GPIO_ACTIVE_LOW>;
	status = "okay";
	w5500: w5500@0 {
					compatible = "wiznet,w5500";
					label = "w5500";
					reg = <0>;
					spi-max-frequency = <8000000>;
					int-gpios = <&gpio0 20 GPIO_ACTIVE_LOW>;
	};
};

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_UART_CONSOLE=n
CONFIG_USE_SEGGER_RTT=y
CONFIG_RTT_CONSOLE=y

# General config

I have a connection and i can ping the address. But the responses takes very long sometimes. And i get a request timed out sometimes. When i ping to google.com or to the host from my computer everything works fine.

I was wondering if anyone has a explanation for this?

thanks in advance

Hi Stefano,

any updates on your issue? Did you get the W5500 running with more stability? We are planning to use the W5500, too... hope the situation has improved in the last two years.

Best regards,

Michael
