Cortex-M1 on Actel - how to start?

Hello ARM Community,

some time ago I started with Cortex-M1 core on Actel Proasic3L FPGA. I don't have much experience, but I have development board without working example:) I tried to follow Actel's tutorials and create simple LED blinking application, but I got stuck. Unfortunately Actel's support can't help me, at least not now, they don't have working dev board with my FPGA and can't duplicate my issue. Now my case is closed, because they wait for new PCBs. I wait more than month and I decided to ask you here for help, because I need to proceed.

In this first project I want just to read 10 switches and turn on/off 10 LEDs. I created Cortex-M1 with peripherals from Actel IPcores. It has CortexM1 core, CoreAHBLite, CoreMemCtrl, CoreAHB2APB, CoreAhbSram, CoreAPB and CoreGPIO. In this case I think that memory map is important.

CoreAHBLite has:

CoreAPB has:

I can synthesize it and load into FPGA. Then I use SoftConsole IDE to prepare application, it is simple, but I'm not sure if correct:

#include "hal.h"

#include "CortexM1_Top_hw_platform.h"

#include "core_gpio.h"

#define GPOUT_INIT_STATE        0x00000000

gpio_instance_t g_gpio;

int main()

{

    uint32_t io_state;

    /**************************************************************************

     * Initialize the CoreGPIO driver with the base address of the CoreGPIO

     * instance to use and the initial state of the outputs.

     *************************************************************************/

    GPIO_init( &g_gpio,    COREGPIO_BASE_ADDR, GPOUT_INIT_STATE );

    while( 1 )

    {

        /**********************************************************************

         * Read inputs.

         *********************************************************************/

        io_state = GPIO_get_input( &g_gpio );

        /**********************************************************************

         * Write state of inputs back to the outputs.

         *********************************************************************/

        GPIO_set_output( &g_gpio, io_state );

    }

}

I build it in Debug and tried to debug, but all what I see is the console output:

source .gdbinit

Could you give me any hint what to do with it?
