To run examples use similar process like for libmaple
examples:

From shell start st-util:

  st-util


and gdb:

  arm-none-eabi-gdb blink1.elf

and on gdb command line

  target extended-remote :4242
  load
  set $sp=0x20001000
  c


Note1: The "set $sp=0x20001000" command above set stack pointer
to the end of RAM on minimal F0 boards (actually, the address
is one byte past the end of RAM, but address is decremented before
store so this is correct value).  On boards which have more memory
we can set it higher.  However with the setting above examples
will work on all boards.  When program is run in normal way
processor reads initial value of stack pointer from first
position in table of interrupt vectors.  However, during normal
start this table is taken from flash which may give wrong
value for our program.  So we set stack pointer by hand and
use "c" (shortcut for "continue") so that program uses our setting.

Note2: Some examples depend on default state of processor.  In
such case when loading program second time first press reset
button and after that load the program.
