My understanding is that linux built in 32bit mode can access this 64bit memory controller using a compile or linker option XPHYS. I cannot find any documentation or examples on how to do this. If you have any suggestions or resources that could be useful, please let me know. Sincerely, David Kesselring -- -------------------------------- W.
