3 years ago This is one set of instructions I found: https://github.com/lawrie/saxonsoc-ulx3s-bin/tree/master/Smp It points back to this project at the end under "Build from Source". Tried connecting a ENC28J60 Adapter as described but can't get it to run.

3 years ago I personnaly never did it, but here is the pinout for the RMII interface as a PMOD : https://github.com/SpinalHDL/SaxonSoc/blob/dev-0.2/hardware/synthesis/radiona/ulx3s/smp/ulx3s_v20_linux_uboot.lpf#L374
It works with the LAN8720 ETH board (https://www.waveshare.com/lan8720-eth-board.htm) @lawrie used it much as far as i know.

3 years ago ok - thanks.
I connected the LAN8720 module and configured the interface with a static IP Address. Good news: I can see the port on my switch and there is traffic. Bad news: something is still wonky.
configured port mirroring so that I can monitor traffic
I can see ARP requests and outgoing ICMP requests. Incoming is sporadic
upon closer inspection I noticed that the broadcast address is off. (check screenshot - should be .255 instead ifconfig shows .55
Related: There aren't many tools in the image - how can I add more networking tools like tcpdump to it?
Thanks

3 years ago disregard the 2nd part - found instructions here: https://github.com/SpinalHDL/buildroot-spinal-saxon

3 years ago interestingly, I now see dhcp queries from the device but it doesn't seem to accept the config (I added networking tools - dhcpd, among others, to the image
adding a static IP-Address and outbound ping shows ARP Requests but no ICMP (as seen from the switch port)

3 years ago This has been solved - I have a working setup with enc28j60. Will try again with LAN8720 as soon as I receive a new one.
Hi again,
The running Linux image shows eth0 - is it possible to connect a LAN8720 Microchip RMII or ENC28J60 Adapter? if so, where can I find the correct pin-out?
Thanks
