Has anyone debugged kernel 2.6.27 using KGDB?

[재용 신]

Hi all.

Has anyone tried to debug kernel 2.6.27 using KGDB?

I'm now trying to use KGDB but I can't use it at all.

I already red documents in kernel source about KGDB and I also know that KGDB is merged since 2.6.26.

Absoultely I'm already done what I have to do in menuconfig like

 

enable KGDB option

enable tty serial

enabel compile with .. and so on..

 

I have embedded board that is target (PXA270, v2.6.27 android kernel) and development PC that is host(2.6.23)

 

Is that a problem that I use lower version kernel in host system?

 

I attached boot parameter in menucofig as follow:

kgdbwait kgdb8250=ttyS0,115200

but When bootloader(BLOB) is loading kernel in embedded board, kernel never wait for host side' gdb signal.

Is there something I missed?

 

I'm now confused slightly. plz help me. o<-< 

 

thanks in advance.

 

Sincerely

 

Shin Jaeyong.
