Hello List, I am attempting to access a peripheral device over the Au1500 static bus. According to the Au1500 Databook, Whenever I set the Chip Select config Register DTY bits to 1 (for "I/O Device"), I must also set Bits 29:26 of CoProcessor 0 to 0xD, to represent bits 35:32 of the Physical address. My question is, if anyone can answer it, is how do I setup The CoProcessor0 registers 29:26 in my driver? I have noticed a set of functions called write/read_c0_entrylo[0,1], But I keep getting random values when invoking these from my driver. Thanks, Gilad.
