Subject: Remote breakpoint problem

Hi,
I am porting gdb to a new target processor were remote debugging is used. I
have a problem with breakpoints. When I place a breakpoint on foo followed
by a continue I see the following communication between gdb and the stub on
the other side:
- the instruction at foo is saved
- foo is replaced by a breakpoint instruction
- gdb sends a continue command
- the stub reports the breakpoint hit (signal = 5, pc = foo)
- gdb replaces the code at foo with the saved instruction
- gdb sends a step instruction command
- tbe stub reports again a breakpoint hit at foo (signal = 5, pc = foo)
- gdb sends a continue command immediatly
So a breakpoint is detected and communicated to gdb but gdb lets the
application continue immediately without giving control to the gdb user.
Does anyone know what is wrong?
I have used breakpoint_from_pc function to supply the breakpoint code.
Thanks,
Jan
