Re: BDI-2000

You are setting your breakpoint at 0x0c000000.  Linux in virtual memory
starts at 0xc0000000.  Am I missing something?

Hello,

I finally got my BDI-2000 for PPC 860 this week, and tried to set it up to
debug my MMU problem.
This is my first time using the BDI-2000, and really hope someone here can
give me a hand.

I am able to check and modify the SRAM (at physical address location 0x0).
and view the bootROM memory
(at physical address of 0x28000000).  I enable the MMU XLAT and set the
PTBASE to 0xf0 as suggested in the
user manual.
Here is the output of the BDI

BDI>reset
- TARGET: processing user reset request
- TARGET: resetting target passed
- TARGET: processing target init list ....
- TARGET: processing target init list passed
BDI>bi 0x0c000000 0x0c00ffff
Breakpoint identification is 0

I never seem to get the break at the location of 0x0c000000.
The same problem if I set the break at location of start_here grep from
System.map

However I do get the break if I set at address location of 0 (start of the
head_8xx.S)
Can someone help me out here??

Thanks

Cecilia

P.S. here is a brief information of my .cfg file which I loaded to BDI
