TI中文支持网Part Number:AM3358
参考SDK文件6.1.9章节：https://software-dl.ti.com/processor-sdk-linux/esd/AM335X/08_02_00_24/exports/docs/linux/How_to_Guides/Host/How_to_Setup_Ubuntu_1404_Network_Boot.html
设置网络启动am335x失败，请问有什么好的建议能帮助我排查问题在哪里吗？

请问log信息是什么？

我看了一下BBB板子的信息，boot mode不支持以太网启动。一直打印CCC，表示进入了UART启动模式。6.8 Default Boot Optionshttps://www.ti2k.com/wp-content/uploads/ti2k/DeyiSupport_DSP_System-Reference-Manual

您好，BBB官方没有说明从以太网启动，但是SDK的开发文档中有提到相关信息，我当前已经有了一些进展，在这里总结一下之前只能打印CCC的原因,希望对别的同学有所帮助：
1. 配置主机DHCP服务器一定要选择插入bbb板卡后检测到的新网卡
2. 如果串口一直打印CCC（可能是bbb板卡没有分配到ip），可手动重启下dhcp服务器，

我把您的问题升级到英文e2e了，请关注下面帖子的回复。https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1108987/am3358-bbb-board-failed-in-network-boot

抱歉回复晚了，刚收到工程师的回复。It seems the BBB is sending out BOOTP packets, but the host is not responding. Seems they need to double check their configuration on the host computer to make sure that DHCP/BOOTP server is configured correctly.
