Using gdbserver or st-flash example blink program is successfully loaded:

2012-05-03T20:11:31 INFO src/stlink-common.c: Starting Flash write for VL core id
2012-05-03T20:11:31 INFO src/stlink-common.c: Successfully loaded flash loader in sram

2012-05-03T20:11:31 INFO src/stlink-common.c: Starting verification of write complete
2012-05-03T20:11:31 INFO src/stlink-common.c: Flash written and verified! jolly good!

However run command of gdb just hangs on Starting program:

(gdb) run
The program being debugged has been started already.
Start it from the beginning? (y or n) y

Starting program: /home/hadrian/devel/engineer/stexample/blink.elf

COM LED on stm32vl is constantly blinking and nothing else happens.
Using st-flash program is loaded, but after clicking reset button nothing happens either.

It's the same for running from SRAM.

Invocation of st-util:

$ st-util -1
