Is it possible to test ethernet module on nRF9160

[Captain CK]

Hello,

I am planning to test ethernet module on nRF9160, use SEGGER SDK  v1.7.0 for compile  the programs. In Q&A I saw using can bus module &  ENC424J600 ethernet controller this can be done. If it is possible can you provide any guide for do the wire connections. If there are other way can you explain with details of required hardware & zephyr libraries.

Thank You.

Hi,

Yes, that should be possible, as this ENC424J600 can interface with the nRF9160 using SPI. The easiest way to test this is if you have some small board or shield with the ENC424J600, that you can connect with some cables to some of the available GPIOs on the nRF9160DK. Zephyr already have drivers for this ethernet device: github.com/.../eth_enc424j600.c

Hi,

Can you provide any wiring diagram to get idea how to connect ENC424J600 can interface with the nRF9160. It will be really help full.

Thanks.

Yes, but do you have any boards/shield with ENC424J600 now? If yes, what is the name of the ENC424J600 board/shield?

Right now I don't have one. But I expect to buy one and test soon as possible.

Ok. Some of the GPIOs on the nRF9160-DK are used for LEDS, buttons, etc. Here is the list over used GPIOs: https://infocenter.nordicsemi.com/topic/ug_nrf91_dk/UG/nrf91_DK/if_connector.html
I recommend using GPIOs that are not in that list when connecting to the ENC424J600.
