Hi,

Here is my example for TLB table configuration: (flash memory)

;--------- SET UP MMU (BEGIN)--------------------------------------------

;table 0

e_lis r5, 0x10000000@ha

e_add16i r5, r5, 0x10000000@l

mtspr mas0,r5 ; mtspr MAS0,r5

e_lis r5, 0xC0000600@ha

e_add16i r5, r5, 0xC0000600@l

mtspr mas1,r5 ; mtspr MAS1,r5

e_lis r5, 0x00000020@ha

e_add16i r5, r5, 0x00000020@l

mtspr mas2,r5 ; mtspr MAS2,r5

e_lis r5, 0x0000003F@ha

e_add16i r5, r5, 0x0000003F@l

mtspr mas3,r5 ; mtspr MAS3,r5

tlbwe ; Write the entry to the TLB

And here is the link for TLB configurator:

Continue the way i show to you and add RAM, or anything required according to reference manual.
