It's still not working for me. I get the following: dwc0: <Rockchip Gigabit Ethernet Controller> mem 0xff540000-0xff54ffff irq 44 on ofwbus0 setting RK3328 RX/TX delays: 24/36 >>> RK3328_GRF_MAC_CON1 (00000413): >>> gmac2io_gmii_clk_sel: 0x0 >>> gmac2io_rmii_extclk_sel: 0x1 >>> gmac2io_rmii_mode: 0x0 >>> gmac2io_rmii_clk_sel: 0x0 >>> gmac2io_phy_intf_sel: 0x1 >>> gmac2io_flowctrl: 0x0 >>> gmac2io_rxclk_dly_ena: 0x1 >>> gmac2io_txclk_dly_ena: 0x1 >>> RK3328_GRF_MAC_CON0 (00000c24): miibus0: <MII bus> on dwc0 rgephy0: <RTL8169S/8110S/8211 1000BASE-T media interface> PHY 0 on miibus0 rgephy0: OUI 0x00e04c, model 0x0011, rev. 6 rgephy0: none, 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT-FDX, 1000baseT-FDX-master, auto >I have Rock64 v2, which, as you mentioned, has a known issue with GigE, so >my tests are not reliable.

That sounds like a good way forward - maybe boot and run-time configurable. It's a pity that there doesn't seem to be any documentation on what the numbers represent (or what the "default" value is) - which means that actually adjusting the delay numbers would be very time consuming. -- Peter Jeremy
