Date: Fri, 03 Aug 2001 09:48:00 -0000 Message-id: X-SW-Source: 2001-08/msg00132.html Hi in hal_platform_setup.h ( iq80310/include), i noticed that we are enabling MMU and then scrubbing sdram starting from RAM_BASE i.e A0000000. Now, my doubt is: since we have mapped the first 4K of RAM to flash, [ mmu_table_rambase: // Map 4k page at 0xa0000000 virt --> 0x00000000 physical // Read-Write, cacheable, non-bufferable ] does that mean writing a 0x00 to a0000000 is same as writing to flash? Am i missing something here? Venkat Worry about chances you miss when you don't even try.
