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.
