[U-Boot-Users] machine check interrupt on AdderII ( MPC852T )

[Raghu]

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;
