it did, thank you.

my new reset routine looks like:

static void cortexm_reset(void *opaque)
{
    qemu_log_function_name();

    CortexMState *cm_state = opaque;
    ARMCPU *cpu = cm_state->cpu;

#if defined(CONFIG_VERBOSE)
    if (verbosity_level >= VERBOSITY_COMMON) {
        printf("Cortex-M core reset.\n");
    }
#endif

    /* Ensure the image is copied into memory before reset fetches msp & pc */
    rom_reset(NULL);

    cpu_reset(CPU(cpu));
}

I had to make rom_reset() non static in hw/core/loader.c and add the prototype 
at the end of hw/loader.h


if you do the same in armv7m_reset() I guess the stm32f205 device will also 
work properly.
