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:

MMU Assist Register CONFIGURATOR

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