Which nios version to use with mSGDMA

I am trying to use the economy nios with the mSGDMA to save streaming data to SDRAM on the DE0-Nano board. Should I be using the standard or fast nios instead. I am not able to get data to even begin...

Krasner,

The msgdma is simple to use, you can do a simple test by creating the descriptors your self using nios. Use the io.h library and use iowr_32Direct(address,offset,value). use the standard descriptor for your test. Make sure when you create the control section to enable the GO bit. This bit tells the dma to execute. ill look into it some more..
