This is the code that will block your progress.
Can you provide the first 8 dwords of the image you ae trying to load?
Maybe you have not initialized all the trap vectors
or you are doing something valid, but unexpected.

Are you loading something else than U-Boot?

As you see, you can disable the check in your configuration file.

#if	defined(CONFIG_APP_CHECK)
/*------------------------------------------------------------------------------*/
/* \fn    df_is_boot_valid							*/
/* \brief Check that the first bytes of the buffer are valid ARM vectors	*/
/*------------------------------------------------------------------------------*/
static unsigned int df_is_boot_valid(unsigned char *buffer)
{
	int i = 3;
 	/* Verify if the 28 first bytes of the sram correspond to ARM vectors
	   The sixth ARM vector contain the size of the code */
    	while(i < 28)
    	{
		if (i != 23)
		{
			if ((buffer[i] != 0xEA) && (buffer[i] != 0xE5) )
				return FAILURE;
		}
		i+=4;
    	}
	return SUCCESS;
}
#endif

> Regards, 

Have now checked the source:

The 2.13 is based on the 1.13 sources.
	
The 1,14 source code is not available on the Atmel.
I will point that out.

	Differences between the 1 series and the 2 series are:
	1) Kconfig - You can do make <board>_config from OpenEmbedded
		If you want to modify something it is much harder
	2) Init of EBI1 of SAM9263
	3) Bus Matrix Initialization
	4) User reset enabled -but it does not work on the G45!
	5) Not depending on a c library.
		Can be compiled with any gcc compiler,
		not just somehing with newlib.
	etc.

	The 1 series is provided by Atmel in Rousset,
	and I have done the 2 series.
