13:16 <grming> hi to all, I modifed the dts and dtsi file for the lichee pi zero board (working with lcd also), and the eth0 even when is recognized eth0: ethernet@1c30000 is not working because at the end of initialitation says : Starting network: Waiting for interface eth0 to appear............... timeout!

13:19 <grming> if I modify the network interface, the when I restart service says: NO SIOCSIFFLAGS

13:36 <apritzel> grming: that's the message from some (networking) init script, right? Did you look for kernel messages?

13:41 <grming> https://pastebin.com/wqXNKED6

14:00 <apritzel> grming: are you sure it's compiled in? the driver doesn't show up in the log at all

14:07 <grming> https://pastebin.com/ZkA5iRJZ

14:07 <grming> at start get rubbish

14:08 <grming> I modified the interafece and get the last output

14:10 <apritzel> grming: is there an ethernet interface at all? does ifconfig list it?

14:12 <grming> ifconfig -a shows nothing.

14:12 <grming> the Loopback only

14:12 <grming> thats way I don't understand. Is shown on init the eth0

14:12 <grming> on interfaces also is shown

14:16 <grming> maybe I forgot something on buildroot

14:16 <apritzel> where is it shown? in some network init script, which hardcodes eth0? if it's not in ifconfig, the driver didn't probe

14:16 <grming> I enable EMAC sun8i on u-boot and also on kernel

14:17 <grming> sorry I only got screen working, not through console

14:25 <grming> https://pastebin.com/1tR0zeUW

14:35 <apritzel> so yeah, there is no eth0 interface, because there is no driver. Are you sure it's really enabled in the config and the driver gets compiled? look for drivers/net/ethernet/stmicro/stmmac/dwmac-sun8i.o

14:36 <apritzel> grming: and also: do you use the right DT, that sets the: status = "okay"; property for the EMAC?

14:40 <grming> i found this page which does the same modification to the dts and dtsi of u-boot and kernel to work with eth0 https://licheezero.readthedocs.io/zh/latest/%E8%B4%A1%E7%8C%AE/article%206.html

14:41 <grming> I tried that but can't make do a ping to some IP direction

14:46 <apritzel> grming: but that's the vendor kernel crap again. Look at sun8i-v3s-licheepi-zero-dock.dts, that enabled Ethernet in mainline

14:48 <grming> ok

19:22 <grming> i found that my ethernet schematics was really bad

19:22 <grming> ougghhh
