TMS320C6678 MAC address error出错，请问是不是因为两个核的NDK所使用的EMAC channel 相同造成的呢？

您好，
  首先非常感谢您的回答。我所碰到的问题是MAC address 出错，是不是因为两个核的NDK所使用的EMAC channel 相同造成的呢？另外，我在NDK USER'S GUIDE 和 NDK software programmer's reference guide 两篇文档中好像没发现有设置EMAC channel 的API 呀。我把我的代码和错误信息贴在下面，还想麻烦您看一下，指出问题所在。
使用的核为 CORE_0  和 CORE_1 ，两个核单独启动 即： Ipc.procSync = Ipc.ProcSync_NONE; // in file.cfg
错误信息如下：
