Hi,
As am I going through the MPC85xx reset.s code, I find this code snippet
below.
I find the Config_sys_monitor is the Text_Base Address in loaded in r3,
The Start Offset is zero, I am not getting why we are subtracting the
start_cont with start and that addr is loaded in the link register where
we jump to.
So what does the address actually refer to? Please Explain.
/* Jump out the last 4K page and continue to 'normal' start */
#ifdef CONFIG_SYS_RAMBOOT
b _start_cont
#else
/* Calculate absolute address in FLASH and jump there
*/
/*--------------------------------------------------------------*/
lis r3,[EMAIL PROTECTED]
ori r3,r3,[EMAIL PROTECTED]
addi r3,r3,_start_cont - _start + _START_OFFSET
mtlr r3
blr
#endif
_Start:
..
..
..
_start_cont:
..
..
..
Thanks & Regards,

I'll post some last-minute UBI fixup patches soon (this week).
