TI中文支持网使用ICE v2 开发板测试PRU Ethernet, 参考链接： http://processors.wiki.ti.com/index.php/PRU-ICSS_Ethernet
ti-processor-sdk-linux-am335x-evm-03.00.00.04做的SD-CARD启动，跳线放在RMII上，CPSW模式网络正常，可以得到IP地址。跳线放在MII上，PRU模式，没有IP地址。

Jian Zhou：
ICE的板子应该是运行的TI RTOS吧，应该是不支持Linux
RAY H：
回复 Jian Zhou:
我是根据这个连接 测试的 ，看上去是用ICE板子 http://processors.wiki.ti.com/index.php/PRU-ICSS_Ethernet
