hi,

kind of new in the nios world, trying to use dma with my uart...

you wrote :

void * rx_buffer = (void*) 0x27000;

can you explain this please ?

I understand that DMA is a cpu feature, is it a default or I need to add it to my system ?

how do you access the the in coming data ?

thank you...
