GDB stub question?

[Inder]

Hi All

I have ported a GDB stub for ARM based system, but when i tried doing
source stepping GDB (GDB 6.4)  host sends the following packet to the
target system:

  ---> $S12#b6

which tell the target to actually do a single instruction step. I
believe in the previous versions of GDB source stepping was done by
setting the breakpoint to the next source line and then continue.

Am i missing something here.

Any help will be appriciated.
