Hi

1) The way you connected the dma in SOPC Builder is correct

2) You are reading data from a pheripheral so i think you need to use these

alt_dma_rxchan_ioctl() & alt_dma_txchan_ioctl() functions

ALT_DMA_SET_MODE_8,

ALT_DMA_SET_MODE_16

for transferring as a byte or halfword to memory

The destination address should be SRAM not Avalan tristate bridge

I too want to know this ,So let me know the correction if you get the result
