Including Wiznet5500 files on the NRF52840DK using VSCode

[Sebastiaan]

Hello,

I am currently integrating the Wiznet5500 drivers into a VSCode project, but I am stuck on where to include these custom modules.

In the previous version in SES (Segger Embedded Studio) these files could be included in the Options --> Preprocesssor --> include paths

Thanks in advance,

Sebastiaan

Hi Sebastiaan,

You should follow the standard west module procedure as described here, in order to do this.

The extension will pick up this as soon as west registers it.

P.S There should also be a Wiznet5500 driver already included in Zephyr as "w5500".

Kind Regards,

Priyanka

Hi Priyanka,

Thanks for the reply. I am currently trying to implement the w5500 driver as per your suggestion.

Is it correct then I only have to include "CONFIG_ETH_W5500=y" to my prj.conf file to include the library?

Also, are there any example projects which use this library?

Thanks in advance,

Sebastiaan

Hi Sebastian,

I guess this ticket would help you.

Hi Priyanka.

Thanks for linking the ticket, compilation is now succesful!

Are there any guidelines or examples on how to implement the W5500 driver? For example a simple network configuration with pinging, ...

Thanks in advance,

Hi Sebastian,

Unfortunately there are no examples of this at the moment.

Hi Priyanka, 

No worries.

I however came across some issues when flashing the included files to the NRF52840DK.

I configured the SPI and W5500 according to my needed pinout (i left out the <> due to the code block)

&spi3 {
	sck-pin = 47;
	miso-pin = 46;
	mosi-pin = 45;
	cs-gpios = &gpio0 44 GPIO_ACTIVE_LOW;
	status = "okay";
	w5500: w5500@0 {
					compatible = "wiznet,w5500";
					label = "w5500";
					reg = 0;
					spi-max-frequency = 1000000;
					int-gpios = &gpio0 20 GPIO_ACTIVE_LOW;
	};
};

However, when flashing this I noticed the following output on the terminal:

11:05:13.235 -> E: >>> ZEPHYR FATAL ERROR 4: Kernel panic on CPU 0

Do you know what could be the cause of this?

With kind regards,

Hi,

It seems like the assert _ASSERT(..) is triggered. You could try to set a breakpoint on this assert and try following the pin assignment back to the call stack to see the problem.

Also, which version of nRF Connect SDK are you using? I would recommend using the latest version. (v1.8.0).

Regards,

Priyanka
