Avalon ST to Memory DMA Example

[Altera_Forum]

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()

Parameters of these functions are the very problem, i have not found a simple example

If you post your (non-)working code and ask a specific question, someone may be able to help you.
