Hi, I'm new to Uboot. Can someone help me. I went through the tbl_table (in tlb.c) and got puzzled by the following entries: ... SET_TLB_ENTRY(1, CONFIG_SYS_FLASH_BASE, CONFIG_SYS_FLASH_BASE_PHYS, MAS3_SX|MAS3_SR, MAS2_W|MAS2_G, 0, 2, BOOKE_PAGESZ_256M, 1), ... SET_TLB_ENTRY(1, CONFIG_SYS_BMAN_MEM_BASE, CONFIG_SYS_BMAN_MEM_PHYS, MAS3_SX|MAS3_SW|MAS3_SR, 0, 0, 5, BOOKE_PAGESZ_16M, 1),

The first entry maps 256M space starting at 0xe800_0000, which is [0xe800_0000, 0xf800_0000) . The second 16M at 0xf400_0000,which is [0xf400_0000, 0xf500_0000) the thing I can't understand is how TLB entries can overlap each other. Isn't it considered a programming error as pointed out in the E5500Core Ref?

I know I must have got something wrong, but I checked the header files and did the calcs again and again, still, nothing dawned on me.

I'm using Freescale T1024RDB board.

please help!!!
