Friends, Am build a 'default' image for GRG(ixp425 based)and single stepping thru it in my sdram. The intial instructions(msr, and, cmp), if single stepped result in will result in R7 having value 0x10000013 and the beq succeeds in brancing to 20070. But if I set a breakpoint further below, and 'go' to that point, then am seeing that R7 gets the value 0x600000D3 and beq fails finally resulting in an exception after few steps.
Why is it that when 'single stepped' the execution proceeds in right path else Gives exceptions?. 00020040 <reset_vector>: 20040: e10f7000 mrs r7, CPSR 20044: e207701f and r7, r7, #31 ; 0x1f 20048: e3570013 cmp r7, #19 ; 0x13 2004c: 0a000007 beq 20070 <start> Am running on a new ixp425 based board.
