Hi,

Thank very much for your info.  I have verified myself and ask one of my
colleague to double check it, but the Kernel Hacking is already disabled.
However it seems there's some thing relate to your supposition, I can run
the kernel without stopping BDM by command:
         g 100000 (or any random  number).

That's fine for me at this time, but it's still a question : BDM problem or
kernel problem?????

Another problem I have is:

    - After the kernel initializing and running,  if I stop the BDM to view
some registers and start again. The BDM will stop and report an breakpoint
happen if I try to press any key on terminal.  Any advices ???

Thank in advances
Hoang

Hoang,
When you are trying to use the Avocet Systems HMI BMD device
have you built a kernel with Kernel Hacking disabled? It appears
from your description the it is still enabled. When kgdb is enabled
through kernel hacking, it starts and immediately hits a breakpoint.
If you at this time set a breakpoint further on then you should be
able to proceed. If you want to use the HMI BMD then you need
to un-select kernel hacking and rebuild your kernel.

Hi All, I have problem when running Linux kernel using BDM. It seems
not a new problem, from this mail list I can learn some thing: Before
run the debugger:
       - Set DER to 0 using BDM command:
                        X  DER
                          30002400f
                          0
      -  Set ICTRL to 7 using BDM command:
              X ICTRL
            00000000
             7
       -  Run the debugger: g
   However, the BDM auto stop right after the kernel execute: (perhaps it

turn on the virtual

mode here)
            execve("/sbin/init",argv_init,envp-init);  in file

/init/main.c

   The BDM show that an breakpoint occur (the PC = 0xFEEDDA8),but of

course I didn't set any breakpoint.

My system is: RPX LITE + HMI BDM + SOURCE GATE II Could anyone please

point me a

solution.
Thank in advances
