Dear U-Boot support,
I'm migrating to new U-Boot version from 2013 and now have Ethernet not working both in U-Boot and in Linux (after booting).
I have custom board with Altera Arria 5 SocFpga onboard. U-Boot version: 2016.03-rc1
In logs I can see:
Net: No ethernet found.
With more verbose:
designware_eth_probe, iobase=ff702000, priv=1eb286a0 ethernet@ff702000 PHY: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 not found designware_eth_probe, ret=-19 No ethernet found.
Ethernet connection inside my board is following: [CPU] ----- [EMAC1] ----- [ FPGA ] ---- [ PHY(KSZ8081MNXIA) ]
I already tried to configure FPGA from Linux environment but it didn't solved the problem. My U-Boot configuration was cloned from socfpga dev kit board with some modifications. But Ethernet configuration I didn't touched yet.
So far I tried to debug it with no success. Also I played with env variables (ethact, ethaddr) and CONFIG_PHY_ADDR with no success as well. Something tells me that I have incorrect EMAC configuration but I don't know how to tackle it.
Please help me identify the problem or at least give me some hints where to look to solve my issue.
Best regards, Denis Bakhvalov
