TI中文支持网大家好，我碰到一个问题。我在C6678EVM跑mcsdk_video_2_1_0_8自带的transcode example 时，发现TFTP 无法下载文件。我已经关闭防火墙、PC和C6678EVM直接连接。具体显示如下：
[C66xx_0] Read tftp config file

Allen35065：
你的这个问题一般都是由PC端FTP服务器的问题引起的，你可以试试先用另一台电脑去下载这个文件看能否下载得到，其它EVM上的设定，包括PC的IP设定应参考文档，应该是可以顺利运行的。

回复 Allen35065:
我也出现类似的问题，利用网线连接PC与EVM时，电脑右下角的网络图标有感叹号，也就是没连接上，我配置的IP就是按照http://processors.wiki.ti.com/index.php/MCSDK_VIDEO_2.1_CODEC_TEST_FW_User_Guide上面的步骤，也不知道是哪里出问题了，运行结果和楼主一样，希望你可以指点一下
