Linux DMA mini2440
Posted: Wed Apr 20, 2011 8:25 am
Hello everyone,
I want use DMA channel 0, source 0 (external device) to my project and i have question: Has anybody any examples how use DMA on mini2440 under linux? I would like transfer data from FIFO (IDT72V2105) which is connected to system bus in mini2440 to SDRAM.
If anyone has some example (maybe Linux DMA API), please let me know.
best regards
michael
