Problems when i reflash the uboot

Hello,

i have an Problem. I had erase the complett NAND. I tried to reflash the uboot over JTAG (openOCD).
But the Dockstar want Boot :-( I only get this Message:

What can i try??

You successfully flashed the boot loader. Now you need to configure the boot scripts to tell the boot loader what to do (or type in the boot commands manually). Jeff's default environment is here:

http://jeff.doozan.com/debian/uboot/files/environment/

That's a binary file which Jeff's boot loader expects at flash memory address 0xc0000. Instead of flashing the binary file, an alternative is to extract the strings from the binary and set the configuration interactively. Either way you must then set the ethaddr variable to the Ethernet MAC address of your Dockstar (six hex values separated by colons, printed on the bottom label).

Thank you for your answear. I have try to reflash the uboot to 0x800000 and the envirnoment to 0xc0000.
But there is the same problem. I dont cant change any thing at the serial terminal.
When i give openocd the command " resume 0x800200" it prints the error and i cant stop the autoboot :(

Is there a uboot version thats doesnt need the environment?

Sorry for my bad English

The boot loader is supposed to be at flash address 0x0. Anyway, you are at the Marvell>> prompt and should be able to interactively enter boot loader commands. Are you sure you have a working serial connection?

Yes i have a working serial connections, but the strange think is, i dont can to any think.
When i press Enter there are do nothing :(

i don´t get it fix :(
can somewone please dump the nand from an working dockstar and upload it?
on with adress is the uboot and the environment? i think my probleme ist that something miss on my empty nand :(

tobi, you already have it fixed... really

hey davy i can´t typ anything at the serial terminal after i run "resume 0x800200" the dockstar restart the uboot at flash and print the enviroment error, i can´t stop the autoboot. The NAND ist Empty, i erased it :(

well... what are you trying to achieve by typing "resume 0x800200" ?
just let it boot to

then enter

printenv

then show us the outputs
of course the nand can't be empty if the board knows who it is. If the nand would be empty it would not show you any output on the serial console. So you definitely not bricked your dockstar.
