    Check if you have enabled CONFIG_PCI_AARDVARK (=y or =m) and in case it is =m then check if you have loaded pci-aardvark.ko module. This is driver for PCIe controller.

    Basically for Marvell Armada 3720 boards you need these options:
    CONFIG_AHCI_MVEBU
    CONFIG_ARCH_MVEBU
    CONFIG_ARMADA_37XX_CLK
    CONFIG_ARMADA_37XX_RWTM_MBOX
    CONFIG_ARMADA_37XX_WATCHDOG
    CONFIG_ARM_ARMADA_37XX_CPUFREQ
    CONFIG_CRYPTO_DEV_SAFEXCEL
    CONFIG_GPIO_MOXTET
    CONFIG_I2C_PXA
    CONFIG_MARVELL_PHY
    CONFIG_MMC_SDHCI_XENON
    CONFIG_MOXTET
    CONFIG_MVMDIO
    CONFIG_MVNETA
    CONFIG_NET_DSA_MV88E6XXX
    CONFIG_PCI_AARDVARK
    CONFIG_PHY_MVEBU_A3700_COMPHY
    CONFIG_PHY_MVEBU_A3700_UTMI
    CONFIG_PINCTRL_ARMADA_37XX
    CONFIG_SERIAL_MVEBU_CONSOLE
    CONFIG_SERIAL_MVEBU_UART
    CONFIG_SPI_ARMADA_3700
    CONFIG_TURRIS_MOX_RWTM
    CONFIG_USB_EHCI_HCD_ORION
    CONFIG_USB_XHCI_MVEBU

    So check that you have all of them enabled.

    Hello @gtbX! Could you please provide output from “lspci -nn -vv” command from working kernel and whole dmesg ouput from non-working kernel? I can look at PCIe issues. In recent kernels there are lot of fixes for pci-aardvark.c A3720 PCIe driver.

    With above PCIe patches, which are now part of Linux 5.8, all PCIe cards should be properly detected.

    EspressoBin does not use SerDes for SGMII (2.5G ethernet) but rather for SATA. Therefore Topaz switch is not connected via SerDes/SGMII but via RGMII which is limited to 1G.

    Armada 3720 has 3 SerDeses and on EspressoBin one is configured in PCIe mode, another in USB3.0 and another in SATA. So there was no free SerDes for SGMII 2.5G. As Armada 3720 has also extra RGMII and authors of EspressoBin wanted to have PCIe, USB3.0 and SATA ports, the only option was to connect ethernet via extra RGMII (1Gbps).

    So enabling 2.5Gbps ethernet on EspressoBin is not possible.

    You can look at Turris MOX device https://www.turris.com/en/mox/ based on same Armada 3720 SOC where SerDes is configured in SGMII 2.5Gbps mode.

    Hello! Following patch https://lore.kernel.org/linux-pci/20200430080625.26070-5-pali@kernel.org/ should fix this problem. It configures controller GEN speed based on speed of connected card. So for GEN1 cards is configured SPEED_GEN_1 and for GEN2 cards is configured SPEED_GEN_2.

    If you still have more PCIe cards available, could you test them if they finally work with above mentioned patch series on Espressobin?

    Hello! I sent patch series for PCIe controller to linux-pci mailing list which should fix most of the problems with different Compex wifi cards on Armada 3720 boards, including Espressobin.

    https://lore.kernel.org/linux-pci/20200430080625.26070-1-pali@kernel.org/T/#u

    If you have still problems with different wifi cards on Espressobin, try above PCIe patches and let me know if they helped or not.
