@WayneWWW,你好，最后这个c.dts是在板子上反编译出来的，修改的地方主要是:
#include <dt-bindings/gpio/tegra194-gpio.h>
/ {
ethernet@2490000 {
interrupts = <0 194 0x4>, /* common */
<0 186 0x4>, /* tx0 */
<0 190 0x4>; /* rx0 */
/* rxq_enable_ctrl = <rx0 rx1 rx2 rx3>
* 0x0 = Not enabled, 0x1 = Enabled for AV
* 0x2 = Enabled for Legacy, 0x3 = Reserved
*/
nvidia,rxq_enable_ctrl = <2>;
nvidia,num-dma-chans = <1>;
nvidia,dma-chans = <0>;
nvidia,num-mtl-queues = <1>;
nvidia,mtl-queues = <0>;
nvidia,rx-queue-prio = <0x2>;
nvidia,tx-queue-prio = <0x0>;
/* 0=enable, 1=disable */
nvidia,pause_frames = <0>;
/* no reset GPIO */
//nvidia,phy-reset-gpio = <&tegra_main_gpio TEGRA194_MAIN_GPIO(G, 5) 0>;
phy-mode = "rgmii-id";
nvidia,max-platform-mtu = <16383>;
nvidia,if-name = "ethsw0";
fixed-link {
speed = <1000>;
full-duplex;
};
};
thermal-zones {
CPU-therm {

MAKE_EQOS_TRIP(m40, -40000, 5000);
MAKE_EQOS_TRIP(m5, -5000, 5000);
MAKE_EQOS_TRIP(p30, 30000, 5000);
MAKE_EQOS_TRIP(p65, 65000, 5000);
MAKE_EQOS_TRIP(p100, 100000, 5000);
};
cooling-maps {
MAP_EQOS(m40, 1);
MAP_EQOS(m5, 2);
MAP_EQOS(p30, 3);
MAP_EQOS(p65, 4);
MAP_EQOS(p100, 5);
};
};
};
};
去掉了mdio节点和注释了phy的部分
