Hello. I'm using ARM based system (samsung smdk2443) and u-boot (old, from samsung). Previously, it was set up to use 64 Mb of RAM. But we have 128 Mb on board. I have reconfigured MMU and some definitions (i.e. PHYS_SDRAM_1_SIZE). But then i found out, that virtual addresses 0x835a0000 and 0x875a0000 point to the same physical address. Something is wrong with configuration, but what?
Thanks in advance.
Here is MMU table:
mmu_table: .set __base,0 /* 1:1 mapping for debugging */ .rept 0x600 FL_SECTION_ENTRY __base,3,0,0,0 .set __base,__base+1 .endr
/* access is not allowed. */ .rept 0x800 - 0x600 .word 0x00000000 .endr
.set __base, 0x300 .rept 0x880 - 0x800 FL_SECTION_ENTRY __base,3,0,1,1 .set __base,__base+1 .endr
/* access is not allowed. */ .rept 0x1000 - 0x880 .word 0x00000000 .endr
