Hi,
I am using CW 8.6 ,patched for PQ III MPC8548.
I am trying to use the 36 bit physical addressing available in MPC8548. To avail this facility, I want to use the 16 entry TLB1 array available in the memory unit , which could be used to access the MAS7 registers.
I want to access a memory region between 0x800000000 - 0x80FFFFFFF.
The config settings that I have done for the SPRs are as below.
writespr 624 0x10070000
writespr 625 0x80000900
writespr 626 0x00000008
writespr 627 0x0000003f
writespr 1008 0x00000080
With these configurations I am not able to access the MAS7 registers......
For example ,I would like to know the configuration settings that I should do, access the memory region between 0x800000000 - 0x80FFFFFFF.
I would like to know where I should write the higher order nibble in my configuration code.
Also I would like to know what are all the configuration settings that I need to do to use this 36 bit physical addressing option available in e500v2 core.
Looking for your help
