Hardware Board: Hamgeek E310 (ANTSDR E310 equivalent) PHY: Marvell 88E1512 (detected as 88E1510) Connection: Direct Ethernet to laptop (static IP) Firmware Built from antsdr-fw-patch v0.39, TARGET=ant Vivado 2023.2 Issue Ethernet link comes up during boot then drops and never recovers: macb e000b000.ethernet eth0: Link is Up - 1Gbps/Full - flow control tx macb e000b000.ethernet eth0: Link is Down macb e000b000.ethernet eth0: PHY [...] driver [Marvell 88E1510] (irq=POLL) macb e000b000.ethernet eth0: configuring for phy/rgmii-id link mode PHY re-probes but never re-establishes link. NIC LEDs go dark. Manual ifconfig eth0 down/up doesn't recover. Multiple cables tested. Working comparison tezuka_fw v0.3.5 for the same E310 maintains stable Ethernet with identical DT config (same PHY, same reset-gpios, same phy-mode). Its kernel is linux 6.12.77. Context Building a drone detection platform using E310 + alphafox02/antsdr_dji_droneid decoder. Decoder works (AD9361 at 61.44 MSPS LVDS), but Ethernet instability prevents deployment.
