I initialised memory location corresponding to AIPS_A as tlb 4. Does i need to do anything else to get access?
That should be enough. This is default settings of MMU and also we can see that there are no registers for DSPI_C visible at 0xC3F90000:
Then I used this configuration:
lis r3, 0x1004
mtMAS0 r3
lis r3,0xC000
ori r3, r3, 0x0500
mtMAS1 r3
lis r3, 0xC3F0
ori r3, r3, 0x002A
mtMAS2 r3
lis r3, 0xC3F0
ori r3, r3, 0x003F
mtMAS3 r3
tlbwe
isync
(or this script for Lauterbach debugger: MMU.TLB1.SET 4. 0xC0000500 0xC3F0002A 0xC3F0003F)
... and I can see that the registers for DSPI_C are visible and writeable:
No other settings are necessary in this case.
