cycloneive boot from sd card

Hello to all!

I'm working with a cycloneive board.

I use the program university avalon sd card interface, and i can read and write a file (fat16) from/to a 2GB sd card.

I would copy a .bin file to sd card, generated with "nios2-elf-objcopy -O binary file.elf output_file.hex" command, and store it in in sdram memory for execute it:

int mem=0;

int* pt_sdram=(SDRAM_0_BASE +0x00100000);

unsigned char midata[4];

for(i=2020;i>0;i--){

mem=0;

midata[0]= alt_up_sd_card_read(sd_fileh);

midata[1]= alt_up_sd_card_read(sd_fileh);

midata[2]= alt_up_sd_card_read(sd_fileh);

midata[3]= alt_up_sd_card_read(sd_fileh);

/*

*/

mem=midata[0];

mem<<=8;

mem|=midata[1];

mem<<=8;

mem|=midata[2];

mem<<=8;

mem|=midata[3];

IOWR(pt_sdram,0,mem);

++pt_sdram;

}

//andrun it with:

asm (

"call (SDRAM_0_BASE +0x00100000);"

);

Is it possible?
