Mini2440 dead, U-boot doesn't boot anything. No kernel, No fs.

Hi All,
       This is my first attempt with embedded systems. My mini2440 is
completely down. I tried every tutorial available on the internet, but
nothing's happenening. I wanted to install Angstrom on 

my mini2440 (1GB nand, X35, 3.5 inch display)

I tried all possible SD card boot methods. I can't find the right files and
nothing ever boots.

My last try was as follows:

>> FOR U- BOOT I FOLLOWED: http://wiki.linuxmce.org/index.php/Mini2440

Got u-boot from GIT>make>got the u-boot.bin
Boot machine from NOR
went to 'supervivi'
went to 'download vivi'
sent u-boot.bin via ./s3c
u-boot was recieved.

shifted the NAND/NOR switch

I got the MINI2440# prompt. U-boot working.

>> FOR ANGSTROM

I went through http://narcissus.angstrom-distribution.org/ to make an
image. I downloaded the tar file.
Untarred it, It had the entire rootfs
and in /boot/ it had an uImage file
rebooted machine in NOR mode
selected "download kernel"
sent uImage file via USB using ./s3c
went ok.

used mkyaffs2image tool given with mini2440 (in the DVD) to convert rootfs
untar directory to yaffs. I did:

#mkyaffs2image /path/angstromrootfs/ ./rootfs.yaffs

I got a yaffs file.

rebooted machine in NOR mode
selected "download yaffs"
sent yaffs file via USB using ./s3c
went ok.

but nothing boots....

my printenv is as follows:

Can ne1 plz mention the steps for a 1GB nand x35 mini2440 to boot any os?
(even the qtopia would do! though the downloaded angstrom would be BEST!)

plz help me with the u-boot and kernel files (with links)

Please help. if ne1 can mail me thr contact details on firerocker@gmail.com
it would be very helpful, I can even give a call and get my doubts cleared.

It would be a great help!

k I installed the u-boot256M.bin which came with it... still now idea how
to go ahead with the angstrom installation :(

What does "but nothing boots...." mean? Can you send us more output when
uboot starts the kernel (or at least try to start it) than you sent
already?

So, the u-boot and uImage procedure works.

What are you using to download your zImage with?  DNW, I hope.

Let's try again . . .

What is this file <.s3c>?  Is is not <./s3c2410_boot_usb u-boot.bin>.

Also, after using DNW in NOR to put u-boot in NAND I think you have "lost"
your DNW loader program and possibly the different way they do their bad
block testing.

As far as I am aware:
zimages
DNW in NOR and follow Mini2440 Downloader Instructions OR
uImages
DNW in NOR and follow http://narnia.cs.ttu.edu/drupal/node/131

I need convert zImage to uImage kindly inform me how to convert it. Kindly
maillme the uImage.bin file also send the software currently i am using
fedora -14. I tried mkimage but it didn't work.
 Is it possible to boot from USB instead of SD card????..

Thank You

For a 64M machine: 

[mini2440-bootstrap] # sudo ./uboot/mini2440/tools/mkimage –A arm –O linux
-T kernel -C none –a 0x30008000 –e 0x30008000 -d
kernel-bin/arch/arm/boot/zImage output/uImage

You have change the directories, ie where your zImage is and where you want
the uImage.

Or place mkimage and the zImage in a separate folder and run this command:

./mkimage –A arm –O linux -T kernel -C none –a 0x30008000 –e 0x30008000 -d
zImage uImage

Never heard anyone booting the mini2440 from USB.  Perhaps, bootloader
support for USB is a big challenge!

can i download my uImage using usb port on Fedora12 os.

if it is possible, what is the procedure to do this?

if i can not download uImage using USB port what is the use of usb port????

The Pengutronix BSP distro will put the barebox bootloader on the target
using <usbpush>. Then you can either use tftp to flash the kernel and
rootfs OR tftp to flash the kernel and NFS to give access to a rootfs on
your host machine.

USB ports are used for a lot of other things then just trying to get a
uImage into the target.
