[Ltib] RE: Reg ltib

[Makhija, Neha (IE10)]

Hi Stuart

I need your help!! 
I have one embedded board with coldfire processor. Because of some reason in 
the application, the drivers (Written by our team) are getting closed (whatever 
are opened in the application). To debug the reason for kill of the application 
by the kernel, I used the gdbserver and gdbclient generated by the ltib. It 
showed "SEGMENTATION KILL" and I am not able to debug further. I tried the gdb 
binary image available in the ltib folder but it didn't work.
Can you suggest me a way to debug the application through ltib ??
Secondly, To debug the Kernel drivers, one can use kdb and kgdb. But I am not 
able to find the two in the ltib folder. Is there any other way to debug the 
drivers through ltib?

Thanks in advance!!
Neha

Hi Neha,

I'm not sure about the OOB data question, maybe others on this list or
even on the MTD mailing list know.

As far as your other options go, there are techniques for combining the
kernel and rootfs into a single image (it's a general technique that you
can find on various mailing list).  However in my opinion for most cases
you get more flexibility by having the kernel and rootfs in separate
Flash partitions.
