You are right.
I delete all breakpoints before load the applications again because my
Hardware supports only two
breakpoints. In other case I receive error from GDB. The load is
multistep. In one of steps I must set
an breakpoint to particular address and only one way I found to put it
away is command delete all breakpoints.
As I see no command deletes breakpoint on address. Use breakpoint to
source line is not very good on this place.

It is not possible for stub restart the application. They are often
problem if a remote target is used.
As I wrote set PC to start address works not properly if i.e. interrupts
are enabled.
If application runs from RAM it is lost after Hardware reset.

The only handy way I see is to reload application set all used
breakpoints and start it again.
