Hi, I'm working to update the OS of our costum i.MX6D board. I have a working OS build from Yocto Dizzy (linux-imx_3.10.17). I now try to update to Yocto krogoth with linux-fsl-imx_4.1-1.0.x and u-boot-fslc_2016.07.
The ethernet card (FEC) work correctly in u-boot but not in linux. The driver is loaded correctly. *fec 2188000.ethernet eth0: Freescale FEC PHY driver [Generic PHY] (mii_bus:phy_addr=2188000.ethernet:00, irq=-1)* *fec 2188000.ethernet eth0: Link is Up - 100Mbps/Full - flow control rx/tx* The interface is correctly mount statically. *eth0 Link encap:Ethernet HWaddr 00:1D:E9:00:94:D6* * inet addr:192.168.0.11 Bcast:0.0.0.0 Mask:255.255.255.0* * UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1* * RX packets:0 errors:2 dropped:0 overruns:0 frame:2* * TX packets:6 errors:0 dropped:0 overruns:0 carrier:0* * collisions:0 txqueuelen:1000* * RX bytes:0 (0.0 B) TX bytes:252 (252.0 B)* But I can't see anything going on the network with wireshark. Also, I see that the received packets are in CRC error. * ~# ethtool -S eth0* *NIC statistics:* * tx_dropped: 0* * tx_packets: 6* * tx_broadcast: 6* * tx_multicast: 0* * tx_crc_errors: 0* * tx_undersize: 0* * tx_oversize: 0* * tx_fragment: 0* * tx_jabber: 0* * tx_collision: 0* * tx_64byte: 6* * tx_65to127byte: 0* * tx_128to255byte: 0* * tx_256to511byte: 0* * tx_512to1023byte: 0* * tx_1024to2047byte: 0* * tx_GTE2048byte: 0* * tx_octets: 384* * IEEE_tx_drop: 0* * IEEE_tx_frame_ok: 6* * IEEE_tx_1col: 0* * IEEE_tx_mcol: 0* * IEEE_tx_def: 0* * IEEE_tx_lcol: 0* * IEEE_tx_excol: 0* * IEEE_tx_macerr: 0* * IEEE_tx_cserr: 0* * IEEE_tx_sqe: 0* * IEEE_tx_fdxfc: 0* * IEEE_tx_octets_ok: 384* * rx_packets: 236* * rx_broadcast: 0* * rx_multicast: 0* * rx_crc_errors: 220* * rx_undersize: 0* * rx_oversize: 0* * rx_fragment: 16* * rx_jabber: 0* * rx_64byte: 0* * rx_65to127byte: 197* * rx_128to255byte: 18* * rx_256to511byte: 5* * rx_512to1023byte: 0* * rx_1024to2047byte: 0* * rx_GTE2048byte: 0* * rx_octets: 26079* * IEEE_rx_drop: 0* * IEEE_rx_frame_ok: 0* * IEEE_rx_crc: 220* * IEEE_rx_align: 212* * IEEE_rx_macerr: 0* * IEEE_rx_fdxfc: 0* * IEEE_rx_octets_ok: 0* My i.MX6 is connect directly on an LAN9303 switch by the RMII bus. Here is my dts ethernet node: *#include "imx6q.dtsi"* *...* *&fec {* * pinctrl-names = "default";* * pinctrl-0 = <&pinctrl_enet_axion>;* * phy-handle = <ðphy0>;* * phy-mode = "rmii";* * phy-reset-gpios = <&gpio1 23 0>; /* GPIO1_23 */* * phy-reset-duration = <10>;* * status = "okay";* * mdio {* * #address-cells = <1>;* * #size-cells = <0>;* * ethphy0: ethernet-phy@0 {* * reg = <0>;* * };* * ethphy1: ethernet-phy@1 {* * reg = <1>;* * };* * ethphy2: ethernet-phy@2 {* * reg = <2>;* * };* * };* *};* Someone have an idea of what is going on or what can I look ? thanks
