uClinux on DE2 board

hi all

I have run successfully uClinux on one custom board which has 2MB flash and 8MB sdram. I used nios2- ide .and i have generated romfs.bin amd vmlinux. I stored romfs at 0x00100000.

It displayed following on console.

now I am using DE2 board .it has 4MB flash and 8MB sdram.

I have generated .ptf using SOPC builder with flash(4MB) ,sdram8MB, jtag_uart(irq-1)

uart(irq-2)and timer (irq-0).nothing else .i used same kernel code as custom board.

i changed only mtd partition.like

static struct mtd_partition custom_partitions[] = {

{

.name = "romfs",

.size = 0x200000,

.offset = 0x200000,

},{

.name = "loader/kernel",

.size = 0x200000,

.offset = 0x0,

}

};

and stored new romfs.bin at 0x00200000. but it hanged after some time. i can't able to understood

what is worng with it.it gave following o/p:
