Avalon ST to Memory DMA Example

There is some simple example for doing DMA between an Avalon streaming source and a memory shared with CPU? I have seen SGDMA but C API seem very complex..

I don't know if there is an example floating around, but the API is relatively straight forward for simple tasks.

All you need, basically, is:

alt_avalon_sgdma_open()

alt_avalon_sgdma_construct_stream_to_mem_desc()

alt_avalon_sgdma_do_sync_transfer()
