David,
Did you solve your problem? Have you succeed to make a TSE Small AMC working with Linux/MMU? Thanks - Altera_Forum

Very old thread but I am facing the same issue and have not seen a fix.
I have a working example for one board and have copied their device names exactly and cannot get it to work in my board. Any suggestions? - Altera_Forum
Thanks, I've changed some names in SOPC BUILDER and now it works fine!!!!

The configuration looks ok...
Can you run the software in a debugger, put a breakpoint just before the TX SGDMA init and see what happens? Check if the open call returns any error code. - Altera_Forum
I've used the same name assigned in a reference design I've seen. You can see in the pic attached.

Do you have the two sgdma components in your design and do they have the correct name?
