Odoll, I tried following the guide you pointed out to me re. resetting the U-Boot Env.

Now the output when booting is a bit different:

NAND read: device 0 offset 0x100000, size 0x400000

reading NAND page at offset 0x100000 failed
 4194304 bytes read: ERROR
## Booting image at 00800000 ...
Bad Magic Number

Lyzby:

printenv bootcmd
bootcmd=setenv bootargs $(bootargs_console); run bootcmd_mmc; bootm 0x00800000 0x01100000

printenv bootargs
bootargs=console=ttyS0,115200

I must admit that it doesn't give me a clue. What does it tell you?

Odoll:

You could very well be right. I mailed the previous owner today and he had the OS installed on a USB drive. So it is probably setup for booting from the USB port.

However, I have tried many things today (not always understading the tutorials!) so it is not unlikely I have changed the environment variables myself :-)

Hi everybody,

I have tried booting my Sheevaplug for a couple of hours. I can log into it with the serial console, but all I see is the Marvell>> prompt. If I then enter "boot", I get these messages:

USB:   scanning bus for devices... 1 USB Device(s) found
       scanning bus for storage devices... 0 Storage Device(s) found
** Bad partition 1 **
** Bad partition 1 **
## Booting image at 00400000 ...
Bad Magic Number

The U-Boot version is : U-Boot 1.1.4 (Mar 19 2009 - 16:06:59) Marvell version: 3.4.16

I have tried upgrading the U-Boot according to this guide:
http://www.cyrius.com/debian/kirkwood/sheevaplug/uboot-upgrade.html

But that didn't make any difference. I still get the Bad Magic Number error.

Any advice would be much appriciated!

Thanks,
Martin
