我用NXP官網的開發板 imx6ull-evk,收到開發板后無法啟動系統，一直停止在starting kernel....；但是uboot下，可用dhcp，也可以和另一臺同一網段的linux主機ping通；
我使用MFGTool重新更新系統，BSP版本4.1.15_2.0.0，更新完成后，可以正常啟動kernel，但是無法使用以太網。在uboot模式使用dhcp命令，顯示：
BOOTP broadcast 1
*** Unhandled DHCP Option in OFFER/ACK: 213
DHCP client bound to address xxx.xxx.xxx.xxx (35 ms)
*** Warning: no boot file name; using 'C0A80867.img'
Using FEC1 device
TFTP from server 0.0.0.0; our IP address is xxx.xxx.xxx.xxx; sending through gateway xxx.xxx.xxx.1
Filename 'C0A80867.img'.
Load address: 0x80800000
Loading: *
TFTP error: 'File not found' (1)
Not retrying...
啟動kernel后，輸入ifconfig命令，顯示：
root@imx6ul7d:~# ifconfig
eth0 Link encap:Ethernet HWaddr 00:xx:xx:xx:xx:xx
UP BROADCAST MULTICAST MTU:1500 Metric:1

沒有動態分配inet地址，也沒有inet6的地址，
設備樹中的配置：
&fec1 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_enet1>;
phy-mode = "rmii";
phy-handle = <ðphy1>;
status = "disabled";
};
&fec2 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_enet2>;
phy-mode = "rmii";
phy-handle = <ðphy0>;
status = "okay";
mdio {
#address-cells = <1>;
#size-cells = <0>;
ethphy0: ethernet-phy@2 {
compatible = "ethernet-phy-ieee802.3-c22";
reg = <2>;
};
ethphy1: ethernet-phy@1 {
compatible = "ethernet-phy-ieee802.3-c22";
reg = <1>;
};
};
};
pinctrl_enet2的引腳是配置過的，以太網口的綠燈常亮，黃色間隔2s左右閃一下，
請各位大神幫忙看看
