uClinux Boot problem

Hi,

I am testing my own custom board with EP1C12Q240, Flash=16bit*4M, Sdram=32bit*2M.

My system has NiosII/f Core, uart, jtag-uart, sdram, flash, epcs_controller, timer and some PIOs.

I use U-Boot to boot uClinux of Microtronix 1.4.

When I run bootm command to boot uClinux, there display

I do not know What is wrong?

I use NiosII-IDE to generate vmlinux.bin and romfs.bin and do

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

$ gzip -9 vmlinux.bin

$ mkimage -A nios2 -O linux -T kernel -C gzip -a 0x00800000 -e 0x00800000 -n &#39;Linux Kernel Image&#39; -d vmlinux.bin.gz uImage.img

$ bin2flash –flash=U5 –location=0x00050000 –input=uImage.img –output=uImage.flash

$ nios2-flash-programmer –base=0x00800000 –input=uImage.flash –sof=<path to pgm sof>

$ bin2flash --flash=U5 --location=0x00200000 --input=romfs.bin --output=romfs.flash

$ nios2-flash-programmer –base=0x00800000 –input=romfs.flash –sof=<path to pgm sof>[/b]

--- Quote End ---

Then, run bootm and display above. Can someone help me?

BTW, another question. When I use

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

$ mkimage -A nios2 -O linux -T filesystem -C none -a 0x00a00000 -e 0x00a00000 -n &#39;romfs&#39; -d romfs.bin romfs.img

$ bin2flash --flash=U5 --location=0x00200000 --input=romfs.img --output=romfs.flash

$ nios2-flash-programmer –base=0x00800000 –input=romfs.flash –sof=<path to pgm sof>[/b]

There display

I do not know what different between these two method and which is correct for me and how to deal with the problem.

Thank you,
