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.

"delete *0x3000000" should work.


Also, it sounds like you want "disable", not "delete".

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.

In many cases the stub can handle all of this automatically, manually disabling interrupts et cetera.


debug session breaks because error.


hier is my user-defined command:

set $myvar = 0

define run
if $myvar
printf "\n 000000000000000000000000000 \n"
disable
printf "\n 44444444444444444444444444444 \n"
k
set remotebaud 300
target remote /dev/ttyS3
load reset.elf
symbol-file reset.elf
# set breakpoint to reset vector
b * 0


printf "\n 555555555555555555555555555555 \n"

# start program
c
delete * 0
printf "\n 666666666666666666666666666666 \n"
# kill program
k


printf "\n 222222222222222222222222222 \n"

set remotebaud 300
target remote /dev/ttyS3
load init.elf
symbol-file init.elf
# set breakpoint to end of program
b end_init
# start program
c
# delete all breakpoints (werden nicht mehr benutzt)
clear end_init
#kill program
k
printf "\n 33333333333333333333333333333 \n"
set remotebaud 300
target remote /dev/ttyS3
load sample.elf
symbol-file sample.elf
set $myvar = 1
enable
continue
else
set $myvar = 1
printf "\n 111111111111111111111111111 \n"
continue
end
