Hi3518EV100 - No Ethernet after flashing OpenIPC

[ScreamingBeef]

Flashed the current available release for my SoC (Hi3518EV100) - whilst it boots okay, I am unable to get network access in uboot or OpenIPC.

printenv in uboot, ifconfig in OpenIPC show expected values for network config. It appears that no packets are exchanged on the network, so I am suspecting network is not working at the lowest levels. On the network port itself, activity and link lights are lit, steady.

This is my first time exploring an embedded system so am unsure where to start debugging. Happy to provide as much info as I can.

Can try this: https://github.com/OpenIPC/wiki/blob/master/en/trouble-network.md

Ah thank you, I feel a bit silly for not coming across that myself!

I'll test and report back

Tried the options in the network trouble page with no success. Should I raise this in Telegram instead of as a github issue?

Had the same issue, used stock uBoot as a workaround (stock has 256k env partition so the layout is different), used a guide from HERE

Copying env variables from stock didn't work either:
phyaddru=0
phyaddrd=1
mdio_intf=rmii

Interestingly ipctool shows:
ethernet:
u-mdio-phyaddr: 1
phy-id: 0xffffffff
d-mdio-phyaddr: 0
phy-mode: mii

Thanks for the guide, I'll work through it this evening. Might try SPI to write a clean OpenIPC image too, i've made a lot of changes during testing and it's possible I've created my own conflicts.
