TI中文支持网根据之前的询问了解sdk6.0的版本的pru驱动已经可以支持单emac驱动
我在移植完成新的sdk之后，按照doc/devicetree/binding/net/ti-prueth.txt更改了设备树，但是pru驱动会报访问空指针的错误
使用的设备树是am572x-idk.dtb,pru部分修改如下

请问您这个问题解决了吗？看您之前的帖子解决了。

回复 Shine:
没有，这个就是移植完成新的内核之后，新版的pru驱动报错

请问Dual EMAC 可以运行吗？
user6163268：
回复 Shine:
不可以，因为只连接了一个phy，只使用了pru2 mii1这个，使用的时候会报错

回复 user6163268:
请尝试按照下面的几点修改一下 am57xx-idk-common.dtsi
1) comment out the alias ethernet2:
aliases { …
ethernet2 = &pruss2_emac0;
…
}2) modify pruss2_eth node in the same way that they did for am572x-idk.dts
3) comment out the subnode pruss2_eth0_phy:
&pruss2_mdio {…
pruss2_eth0_phy: ethernet-phy@0 {
reg = <0>;
interrupt-parent = <&gpio3>;
interrupts = <30 IRQ_TYPE_EDGE_FALLING>;
};
…
};
