T1024 ehernet interface doesn't up

kriptonus — Thu, 24 Oct 2024 07:56:37 GMT

Hi everyone!

I've tried to compile an image for the t1024 based board. For the building I've used a Buildroot tools and fresh kernel 6.1.44. But ethernet interfaces doesn't up although

ip a

show me a list of interfaces

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000 link/ether 00:00:00:00:01:00 brd ff:ff:ff:ff:ff:ff 3: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000 link/ether 00:00:00:00:01:01 brd ff:ff:ff:ff:ff:ff 4: eth2: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000 link/ether 00:00:00:00:01:02 brd ff:ff:ff:ff:ff:ff 5: eth3: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000 link/ether 00:00:00:00:01:03 brd ff:ff:ff:ff:ff:ff 6: tunl0@NONE: <NOARP> mtu 1480 qdisc noop qlen 1000 link/ipip 0.0.0.0 brd 0.0.0.0 7: sit0@NONE: <NOARP> mtu 1480 qdisc noop qlen 1000 link/sit 0.0.0.0 brd 0.0.0.0

trying

ip link set dev eth0 up

give me an error

fsl_dpaa_mac ffe4e0000.ethernet eth0: init_phy() failed

During a boot log I can watch this:

mdio_bus 0x0000000ffe4fc000: MDIO device at address 2 is missing. mdio_bus 0x0000000ffe4fc000: MDIO device at address 6 is missing. mdio_bus 0x0000000ffe4fd000: MDIO device at address 1 is missing. mdio_bus 0x0000000ffe4fd000: MDIO device at address 2 is missing. platform ffe488000.port: Adding to iommu group 15 platform ffe489000.port: Adding to iommu group 16 platform ffe48a000.port: Adding to iommu group 17 platform ffe48b000.port: Adding to iommu group 18 fsl_dpaa_mac ffe4e0000.ethernet: FMan MEMAC fsl_dpaa_mac ffe4e0000.ethernet: FMan MAC address: 00:00:00:00:01:00 fsl_dpaa_mac ffe4e2000.ethernet: FMan MEMAC fsl_dpaa_mac ffe4e2000.ethernet: FMan MAC address: 00:00:00:00:01:01 fsl_dpaa_mac ffe4e4000.ethernet: FMan MEMAC fsl_dpaa_mac ffe4e4000.ethernet: FMan MAC address: 00:00:00:00:01:02 fsl_dpaa_mac ffe4e6000.ethernet: FMan MEMAC fsl_dpaa_mac ffe4e6000.ethernet: FMan MAC address: 00:00:00:00:01:03 fsl_dpaa_mac ffe4e0000.ethernet eth0: Probed interface eth0 fsl_dpaa_mac ffe4e2000.ethernet eth1: Probed interface eth1 fsl_dpaa_mac ffe4e4000.ethernet eth2: Probed interface eth2 fsl_dpaa_mac ffe4e6000.ethernet eth3: Probed interface eth3

Is it true that the MDIO is not configured correctly? I use a device tree from kernel source, Uboot has been kept from previous image (kernel version 3.12.27). I've loaded a new rootfs, dtb and uImage into ram and ran from there.

ethtool show me the next:

ethtool eth0 Settings for eth0: Supported ports: [ ] Supported link modes: Not reported Supported pause frame use: No Supports auto-negotiation: No Supported FEC modes: Not reported Advertised link modes: Not reported Advertised pause frame use: No Advertised auto-negotiation: No Advertised FEC modes: Not reported Speed: Unknown! Duplex: Half Port: Twisted Pair PHYAD: 0 Transceiver: internal Auto-negotiation: off MDI-X: Unknown Current message level: 0x00002037 (8247) drv probe link ifdown ifup hw Link detected: no

Is there some tricks to use ethernet on T1024?

I tried to compile new image from QorIQ SDK 2.0, but it has a very old tools and stopped with a lot of errors.

Please modify the dts file arch/powerpc/boot/dts/fsl/t1024rdb.dts according to your custom board. Please modify "reg" values to your real PHY addresses at mdio@fc000 and mdio@fd000.

fman@400000 {
enet0: ethernet@e0000 {
phy-handle = <&xg_aqr105_phy3>;
phy-connection-type = "xgmii";
sleep = <&rcpm 0x80000000>;
};

enet1: ethernet@e2000 {
sleep = <&rcpm 0x40000000>;
};

enet2: ethernet@e4000 {
phy-handle = <&rgmii_phy2>;
phy-connection-type = "rgmii";
sleep = <&rcpm 0x20000000>;
};

enet3: ethernet@e6000 {
phy-handle = <&rgmii_phy1>;
phy-connection-type = "rgmii";
sleep = <&rcpm 0x10000000>;
};

mdio0: mdio@fc000 {
rgmii_phy1: ethernet-phy@2 {
reg = <0x2>;
};
rgmii_phy2: ethernet-phy@6 {

};
};

xmdio0: mdio@fd000 {
