Up to the last line, mine is quite similar, but obviously is failing: [ 1.020777] sun7i-dwmac 1c50000.ethernet: PTP uses main clock [ 1.026532] sun7i-dwmac 1c50000.ethernet: no reset control found [ 1.032623] sun7i-dwmac 1c50000.ethernet: no regulator found [ 1.038338] sun7i-dwmac 1c50000.ethernet: Ring mode enabled [ 1.043908] sun7i-dwmac 1c50000.ethernet: DMA HW capability register supported [ 1.051141] sun7i-dwmac 1c50000.ethernet: Normal descriptors [ 1.064623] libphy: stmmac: probed [ 1.068081] sun7i-dwmac 1c50000.ethernet (unnamed net_device) (uninitialized): PHY ID 0007c0f1 at 1 IRQ POLL (stmmac-0:01) active > [ 19.287489] RTL8211E Gigabit Ethernet stmmac-0:00: attached PHY driver > [RTL8211E Gigabit Ethernet] (mii_bus:phy_addr=stmmac-0:00, irq=-1) > [ 19.302199] sun7i-dwmac 1c50000.ethernet eth0: RX IPC Checksum Offload > disabled > [ 19.309560] sun7i-dwmac 1c50000.ethernet eth0: No MAC Management Counters > available > [ 19.317256] sun7i-dwmac 1c50000.ethernet eth0: PTP not supported by HW > [ 19.324710] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready > [ 20.330756] sun7i-dwmac 1c50000.ethernet eth0: Link is Up - 1Gbps/Full - > flow control rx/tx > [ 20.339322] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready [ 7.449305] Generic PHY stmmac-0:01: attached PHY driver [Generic PHY] (mii_bus:phy_addr=stmmac-0:01, irq=-1) [ 7.460675] sun7i-dwmac 1c50000.ethernet eth0: RX IPC Checksum Offload disabled [ 7.468034] sun7i-dwmac 1c50000.ethernet eth0: No MAC Management Counters available [ 7.475686] sun7i-dwmac 1c50000.ethernet eth0: PTP not supported by HW [ 8.488733] sun7i-dwmac 1c50000.ethernet eth0: Link is Up - 100Mbps/Full - flow control rx/tx [ 8.884664] NET: Registered protocol family 10 [ 8.940520] Segment Routing with IPv6 It looks like my device is not configured. > Your board has an RTL8201CP PHY rather than the RTL8211E above, but it > should still be using the GMAC controller (the A20 core has two > different Ethernet controllers, but GMAC's generally preferred over > EMAC).

Well, I am stuck! This is new territory for me to some extent as my prior experience is on X86 hardware and with a couple of Raspberry Pis. I was hoping to get parazyd's attention who made these Devuan images back in May so we can sort this out for the project. I'm not sure if he monitors this list or not. - Nate -- "The optimist proclaims that we live in the best of all possible worlds. The pessimist fears this is true."
