Hi,
I am getting this "Machine Check Interrupt" at one Instruction. But using BDI if I proceed using "go" command, it goes ahead fine.
The instruction I am getting this is at "0xfe0024fc" ***************************************************** BDI>go 0xfe000100 - TARGET: target has entered debug mode BDI>i Target state : debug mode Debug entry cause : machine check interrupt Current PC : 0xfe002500 Data address : 0x00000000 DSISR value : 0x080a0000 BDI>
*************************************************** The equivalent assembly listing is as below, from function "cpu_init_f" in file "cpu/mpc8xx/cpu_init.c" ---------------------------------------------------- #if (defined(CFG_OR1_PRELIM) && defined(CFG_BR1_PRELIM)) memctl->memc_or1 = CFG_OR1_PRELIM; fe0024e0: 3d 60 ff 80 lis r11,-128 fe0024e4: 61 08 00 01 ori r8,r8,1 fe0024e8: 91 03 01 00 stw r8,256(r3) fe0024ec: 94 21 ff e8 stwu r1,-24(r1) fe0024f0: 61 6b 0e 00 ori r11,r11,3584 fe0024f4: 91 49 00 04 stw r10,4(r9) fe0024f8: 90 03 01 00 stw r0,256(r3) memctl->memc_br1 = CFG_BR1_PRELIM; fe0024fc: 38 00 00 81 li r0,129 fe002500: 91 49 00 04 stw r10,4(r9) fe002504: 91 69 00 0c stw r11,12(r9) fe002508: 90 09 00 08 stw r0,8(r9) #endif ---------------------------------------------------
