Hello,
this happens with F7-Disco and Nucleo-F7.
When board is just powered up by plugging in the Stlink, initial connect to the
board does not see the right number of breakpoints:
t520 > src/openocd -s tcl -f tcl/board/stm32f7discovery.cfg
...
> Info : stm32f7x.cpu: hardware has 0 breakpoints, 10 watchpoints
Only by keeping the reset button of the board pressed while openocd is started
make openocd see the right number.
Find attached "openocd1" as a -d3 log when the wrong number of breakpoints is
seen.
