Hello,

I am trying to figure out how to make a program from user land that can
use the DMA controller. I would like it to read values, returned from
the SPI port, and store the values in the SDRAM. Can this be done?

I have figured out that I need to use a physical address when
programming the DMA controller, not a virtual address such as is used in
application programs. Is there a way to find the physical address from
the virtual address?

Thanks in advance to anyone who can help.
