How do you suggest I go about enabling the data cache with out running into the machine check exception (0200 exception).
I need the data cache as there is lot of data access in the applications we run on our SDH unit. OS Montavista 3.0 Processor MPC8260 Register required to madify: HID0 (bit 17 to be set) => controlword is: HID0 OR 000004000 => sets the 17th bit but this gives me the 0200 exception are there any kernel routines I can run to get this to work?
