Altera_ForumIf you use the uCOS operating system and the Interniche TCP/IP stack, like in the simple socket server example, then you don't need to worry about the sgdma transfers. Those are done by the IP stack. Just use the standard sockets API.

The source code is located with the altera ip in the altera installation. The easiest way to locate the relevant code snippets is to use a search engine and look for function names.
